Airbag error 16

sensor that was replaced per the code scanner , That's where you made your mistake . No code tell's you to replace a part without testing . Did you do factory trouble shooting per code diagnostic testing procedures ?
The inflatable restraint front end sensor utilizes a unidirectional 2-wire circuit. The front end sensor modulates current on the interface to send ID, state of health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and a ground for the front end sensor. When the ignition is turned ON and input power from the SDM is first detected, the front end sensor responds by performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds. The front end sensor continually communicates status messages to the SDM, which determines if a fault is present in the front end sensor circuit. When a fault is detected, the SDM may reset the front end sensor up to 2 times by removing and reapplying power to it. If the fault is still present, the SDM will set a DTC.

B0091 00
• The front end sensor has been shorted to voltage, open, or shorted to ground.
• The front end sensor current has been above 23 mA for longer than 5 milliseconds.
• The SDM has not received a message from the front end sensor for more than 375 milliseconds.

Circuit/System Testing
Important: When removing the connectors, inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:
• Front end sensor
• SDM module
• Front end sensor wiring harness connector
• SDM wiring harness connector
Ignition OFF, disconnect the harness connector at the front end sensor and the SDM.
Ignition ON, test for less than 1 volt between the front end sensor signal circuit terminal 2 and ground.
? If greater than the specified range, test the signal circuit for a short to voltage.
Ignition ON, test for less than 1 volt between the front end sensor low reference circuit terminal 1 and ground.
? If greater than the specified range, test the low reference circuit for a short to voltage.
Test for infinite resistance between the front end sensor signal circuit terminal 2 and ground.
? If less than the specified value, test the signal circuit for a short to ground.
Test for infinite resistance between the front end sensor low reference circuit terminal 1 and ground.
? If less than the specified value, test the low reference circuit for a short to ground.
Test for less than 1 ohm between the SDM signal circuit terminal 38 and the front end sensor circuit terminal 2 harness connector.
? If greater than the specified range, test the signal circuit for an open/high resistance.
Test for less than 1 ohm between the SDM low reference circuit terminal 36 and the front end sensor circuit terminal 1 harness connector.
? If greater than the specified range, test the low reference circuit for an open/high resistance.
If all circuits test normal, test or replace the front end sensor.
Reconnect all SIR components. Ignition ON, verify the DTC is not set as current.
? If the DTC resets as current, replace the SDM.

P0652 DODGE - 5 Volt Sensor Reference 2 Circuit Low
These 5-volt reference circuits are independent of each other outside the PCM, but are bussed together inside the Engine Control Module (ECM). Therefore a circuit condition on one sensor 5-volt reference circuit may affect the other sensor 5-volt reference circuits. The ECM monitors the voltage on the 5-volt reference circuit.

Possible causes
- Shorted sensor
- Shorted sensor circuit
- Failed ECM

When is the code detected? The ECM has detected an out of voltage range on the 5 volt reference circuit 2.

Hope helps.

Hello www_ropesmor,

This code P0123 is Throttle position sensor circuit high input.

There four basic reasons for this code.

1. An open or short to ground between the TPS (throttle position sensor) and the ECM (Engine control module).
2. A short to battery voltage between TPS and the ECM.
3. A short between the TPS wires.
4. A faulty TPS.

See below for connector diagrams.

First, with scan tool monitor TPS with throttle closed voltage should be
I f you don't have a scan tool, back probe terminal 1with a volt meter to ground and you will see the voltage as outlined above otherwise follow the steps below.


1.Check to see if there is about 5 volts at the TPS; with engine off key on disconnect the TPS back probe the harness side terminal 3 to ground with a volt meter if there is about 5 volts go to step 2 if about 5 volts if not repair the 5 volt circuit.

2. Probe the harness side terminal 2 to chassis ground with a volt meter, if voltage above .02 repair circuit 2 short to voltage. If voltage is .02 volts or below go to step 3.

3. Probe the harness side terminal 1 to ground with volt meter if below .5 volts go to step 4 if not repair short to battery between TSP harness and ECM connector

4 Turn the ignition off and disconnect the ECM connector . With an ohm meter measure the resistance between the ECM (terminal C18) and TPS ground circuit it should be below 1 ohm. Measure the resistance between the ECM (terminal C8) and TPS signal circuit it should be below 1 ohm. If not repair the open circuit.

After faulty circuit is found and repaired clear code and verify repair.







I hope this helps.

Most of this came from TSB 98-T-49A, and a few of my tips thrown in.

Both P0340 and P0341 both relate to the Camshaft Position Sensor(I will just call it Cam sensor from now on), the only problem is that the S-Series engines don't have a Cam sensor, not a typical one at least. instead, the DIS module watches when the #4 spark plug fires on the compression cycle and fakes a Cam sensor signal from it. the tricky part is that on a DIS waste spark system, spark plugs fire with their mated cylinders(1/4 and 2/3 in 4 cylinder engines) every time the cylinder is at TDC, regardless of weather the cylinder is on exhaust or compression. However, it takes far more voltage to fire a spark plug on the compression stroke then on the exhaust stroke, due to the compressed air(more air molacules, more air the spark needs to jump, more resistance to spark). The increased voltage needed on the compression stroke is detected by the "#4 sensing circuit" inside the DIS module for the Cam sensor signal. if the resistance of the secondary system is not in the proper range or something else is affecting the voltage draw, the "#4 sensing circuit" will be unable to work properly.

In short, anything worng with the ignition system, bad Cam sensor signal.

Next for the diagnositic, i'm converting this from a graphic map to a text format, so bear with me...

Step 1: remove secondary wires from spark plugs, keep the wires on the coil. measure resistance from #1 wire to #4 wire and then #2 wire to #3 wire. resistance should be 11k ohms to 45k ohms(YIKES thats a wide range)

If resistance is in specs, go to step 2, if not in specs, go to step 3


Step 2: remove secondary wires from the coil packs. check for corrosion on the towers and wires.

If there is corrosion, go to step 4

If not, go to step 5


Step 3: remove secondary wires from the coil packs. check for corrosion on the towers and wires.

If there is corrosion, go to step 4

If not, go to step 6


Step 4: Replace or clean coils and/or wires as nessaciry. Retest to confirm.


Step 5: Remove spark plugs. Check for carbon or abnormal wear and proper gap(0.040 in)

If plugs check out good, go to step 8.

if the plugs are bad, replace as needed and retest to confirm.


Step 6: Measure resistance of individual secondary wires. specs are 1.5k ohms to 15k ohms ( thats what this chart says, but my knowage says 8k ohms is normal, greater then 12k ohms should be replaced)

If wires are in spec, go to step 7

If wires are bad, replace as needed and retest to confirm


Step 7: Measure resistance from tower to tower on the coil packs (hold tight for good reading). Spec is 8K to 15K.

If coils are in spec, go back up to step 5

If coils are bad, replace as needed and retest to confirm


Step 8:(90% of the time i bet the problem is solved by now) Start engine. Perform underhood visual inspection of the ignition system, check for arcing(best done in a dark area, if you are inside a garage, besure the exhaust is vented). Wet DIS module, coils, and secondary wires with salt water to provide optional ground path.(arcing from the wire boot to the valve cover is possible, but would be hidden)

If arcing is present, replace wires or coils as needed and retest to confirm.

If not, go to step 9.


Step 9: Turn ignition off, backprobe J3D03 (Circuit 633, brn/wht wire) at PCM with voltmeter. connect other lead to ground. Turn ignition on, engine off. Measure voltage.

less then 4.5 volts, go to step 10
4.5-5.5 volts, go to step 12
more then 5.5 volts, go to step 11


Step 10. Check connections in circult 633, repair short to ground, retest to confirm


Step 11. Repair short to voltage in circuit 633, retest to confirm.


Step 12. Start engine, at idle observe voltmeter

less then 2.0 volts, replace DIS module, retest to confirm
2.0 - 4.0 volts, problem intermittent
4.0 - 5.5 volts, go to step 13
more then 5.5 volts, go back up to step 11


Step 13. Turn ignition off, backprobe circuit 633 at DIS module with voltmeter, other lead to ground. check voltage.

4.0 volts or less, repair open/high resistance in circuit 633, retest to confirm.
greater then 4.0 volts, go to step 14


Step 14: Inspect terminal on DIS module for looseness or poor connection.

If terminal is bad, repair it
If terminal is good, replace the DIS module.



thats all of the diagnoistic chart, anybody who has done this in the past feel free to throw in your tips/opinons. I would like to add three things:

1. Check the grounding bolt on the DIS module for corrosion.
2. besure the secondary wires are fully seated, you should feel/hear a click
3. use dielectric grease on the coil towers

This is one of two things, if the truck goes into drive and moves then you have trany problems and may need to have it rebuilt, if there is no movement in reverse or drive then it could be the transfer case or trany.

Possible Cause
The following items may be area of concern:
?¬Other transmission-related DTCs are set.

?¬Sensor signal circuit has short to ground, short to voltage or open.
?¬Governor pressure sensor defective.
?¬Transmission fluid burnt or oil pan contains excessive debris.
?¬Governor pressure out of range.
?¬Transmission leaking internally.
?¬Defective PCM.
?¬Defective valve body.

Diagnostic Procedure
1.Using scan tool, read DTCs. If good trip counter for DTC P1756 is not displayed or displayed count is not zero, go to step 25. If good trip counter is displayed and displayed count is zero, go to next step.
2.Repair any other transmission-related DTCs before proceeding. If no other transmission-related DTCs exist, go to next step.
3.Check transmission fluid for proper level and for any debris. Fill or repair transmission as necessary. If fluid level and condition are okay, go to next step.
4.Start engine. Allow engine to reach normal operating temperature. Set parking brake, depress brake pedal and place gearshift lever in "D" position.

Inspect connector and terminals for damage. Repair as necessary. Measure resistance of governor pressure sensor 5-volt supply circuit between governor pressure/temperature sensor harness connector terminal "A" and transmission solenoid harness connector terminal No. 2. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace transmission solenoid assembly (internal transmission harness).
13.Measure resistance of sensor ground circuit between governor pressure/temperature sensor harness connector terminal "D" and transmission solenoid harness connector terminal No. 3. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace transmission solenoid assembly (internal transmission harness).
14.Measure resistance of governor pressure sensor signal circuit between governor pressure/temperature sensor harness connector terminal "B" and transmission solenoid harness connector terminal No. 4. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace transmission solenoid assembly (internal transmission harness).
15.Measure resistance of governor pressure sensor signal circuit between ground and governor pressure/temperature sensor harness connector terminal "B". If resistance is less than 5 ohms, replace transmission solenoid assembly (internal transmission harness). If resistance is 5 ohms or more, go to next step.
16.Measure resistance between governor pressure sensor signal circuit and sensor ground circuit at governor pressure/temperature sensor harness connector terminals "B" and "D". If resistance is less than 5 ohms, replace transmission solenoid assembly (internal transmission harness). If resistance is 5 ohms or more, go to next step.
17.Reconnect transmission solenoid assembly harness connector. Turn ignition on. Measure voltage of governor pressure sensor signal circuit between ground and governor pressure/temperature sensor harness connector terminal "B". If voltage is more than one volt, replace transmission solenoid assembly (internal transmission harness). If voltage is one volt or less, go to next step.
18.Turn ignition off. Using DVOM, backprobe governor pressure sensor signal circuit at PCM harness connector C2 (White) terminal No. 29. Start and idle engine. Place gearshift lever in "N" position. Using scan tool, observe governor pressure sensor voltage. Compare scan tool value with DVOM voltage. If voltages match, replace governor pressure/temperature sensor. If voltages do not match, replace PCM.
19.Turn ignition off. Ensure transmission solenoid harness connector is disconnected. Disconnect PCM harness connector C2 (White). Measure resistance of 5-volt supply circuit between transmission solenoid harness connector terminal No. 2 and PCM harness connector C2 (White) terminal No. 31. If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or more, repair 5-volt supply circuit for open.

NOTE: Removing transmission control relay in the following step may set other DTCs. Disregard these DTCs.

When fixing codes start with first code first / it dos not always mean that the sensor is the fault ,it could be in the harness / the plug or the ground. and reference signal should be tested , but in this case you most likely could get away with replacing the cam sensor, that would be the Lest expensive and easiest to start with,to git to it you will have to remove the alternator hope this is help full, the other code suggest that it could be the crank sensor , that and the plug for it does fail quite often but first things first feel free to ask if you should have any further questions , Thank you ,

It's quite likely that you have an open circuit between the fuel sender harness and the chassis ground. This would cause this combination of DTC's as the ground is a common point for both of these components.

With the key on, engine off, disconnect the cam position sensor wire (3 pin connector) and check the ground for resistance between pin 3 and a chassis ground. You should have less than 1 ohm of resistance. If not then a ground issue is your problem, either obtain a schematic from www.hmaservice.com for your vehicle and check the wire for resistance at each connector from the CMP (cam position sensor) to the ground, or take your vehicle to a local Hyundai dealer who will have the resources to do so correctly in the shortest amount of time.

Cam position sensors go bad, but very infrequently. We see many more Crank position sensors (people confuse the two quite frequently) go bad. In your case, the cam position sensor would be located on top of the cylinder head, not in the engine block. It's located between the valve cover (the very top of the engine, the oil cap is on it) and the coil pack (the thing on the right with the spark plug wires). The connecter between them is what you need to check. Any digital voltage and ohm meter (DVOM) will due. Pin 1 should be 12 volts DC, pin 2 should be 5 volts DC, and I mentioned how to check the ground.

If you get stuck, take it to a dealer. Pin 2 on this connecter goes directly to the PCM (Powertrain Control Module) and you don't want to cook that by shorting it to 12 volts.

Good luck!

Good luck!

CODE 41
It means problems with ignition module. Remove the wiring harness connector from the module the resin that encapsulates the module circuit board was oozing out of the connector. try changing the ignition module or it may heve problems with the cam sensor . Check whether cam sensor interrupter (magnet) had broken off the cam gear.
