SOURCE: P0705

sounds like the trans range sensor or it could be internal trans problem. is the trans shifting ok? if not, it might need an overhaul. the sensor might be something you can tackle but it's on top of the trans right below the air filter housing. it the sensor that the shifter cable is connected to. you'll have to have it in neutral to install it as the sensor has line up marks on it.

P0705 - Trans Range Switch Circuit

Get under the truck and look where the trans shift linkage connects to the trans, there is a post that comes out of the trans, on that post u will see a large switch with multipile wires connected to it, that is the range selector switch, you need to remove the shift arm and a couple of bolts to remove the range switch, it is adjustable, u will see the slots, make sure u put the new switch in the same position as the old one or the truck may not start.

I would check the neutral safety switch. It's located on the shift shaft of the transmission and is known to go bad

SOURCE: p1744 enginge code tcc solenoid circuit

DTC P1744 is "TCC - Excessive Slip Detected During Full TCC Engagement". Which means that the Torque Converter Clutch (TCC) is disengaged or the EPC pressure is at the minimum.

The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.

If the TCC and wiring is okay, then pressure testing of the transmission will need to be done.

A new torque converter from Ford is about $265.00 and about 4 hours labor. Throw in a $40.00 TCC solenoid and I don't think it'll be more than $700.00 at worst.

If the pressure test is good then it's just going to be the $40.00 tcc solenoid and the cost of the transmission oil and filter changed which should be around $150.00

Good luck and hope it's just a loose wire harness to the solenoid which would cost $0.00 and just your time to locate the break in the wire. The other thing to, is to add a transmission fluid additive that would restore the clutch pack in the transmission and Torque Converter.

Several thnigs to check there; review all informastion disponible to do it and solve this...

P0356
- Ignition Coil F Primary/Secondary Circuit Malfunction
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM

Possible Solution:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM
------------------------------------------------------------------------------------------------------------------------------------------------

P0152 - O2 Sensor Circuit High Voltage (Bank 2 Sensor 1)
The heated oxygen sensor 1 is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust

Possible Causes:
- Harness or connectors (The heated oxygen sensor 1 heater circuit is open or shorted.)
- Front Heater oxygen sensor heater (Bank 2) may be faulty

Possible Solution:
Replacing the O2 Sensor 1 usually takes care of the problem
------------------------------------------------------------------------------------------------------------------------------------------------

P0174 - Fuel Injection System Too Lean Bank 2
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The ECM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.

In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption

Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection

Possible Solution:
Dirty air filter of faulty air flow sensor are common causes of the problem.
------------------------------------------------------------------------------------------------------------------------------------------------

P2197 - DODGE - Sys Too Rich at Hier Load Bank1
Means that the O2 sensors on each bank are seeing WAY too much oxygen in the exhaust gas. In normal operation the signal from the O2 sensors should swing back and forth between rich and lean. Your sensors are locked on lean.

Those codes are the same as P0174 (and P0171). Sounds like you have a vacuum leak somewhere. Most common place is the PCV elbow where it connects to the throttle body adapter.
------------------------------------------------------------------------------------------------------------------------------------------------


Hope this helps; keep in touch.

I have a 2001 Chevy S10 4 cylinder 2.2L Flex Fuel. I am getting readout from most all Auto Parts stores that my codes are directing me to a sensor problem. These most recent codes were C0268, C0223,...


Now what is my problem? We are not magican , an we do not have magical fix's . Testing is the way to a fix . Each DTC - diagnostic trouble code has a diagnostic flow chart or what to test . Buick Electrical Part 3 Automotive Computer Operation 1990

An the auto parts stores just want to sell you a part , just because the code has a sensor name does not mean the part is bad , all sensors have two or three wire's , all coming from the PCM/ECM - engine computer . The electrical circuit could have a open , short to ground , a short to B+ power . The PCM could have a problem . Never change parts without testing . An if that's all you can do , then you need to take it to a qualified repair shop .

DTC P0705
Transmission Range (TR) Switch Circuit

The transmission range (TR) switch is part of the park/neutral position and back-up lamp switch assembly and is externally mounted on the transmission manual shaft. The TR switch is a multi-signal switch. The PCM supplies ignition voltage to the TR switch on four signal circuits (A, B, C, and P). Each gear selector lever position grounds one or more of the switch circuits. In order to determine the gear range selected by the driver, the PCM compares the voltage combinations on the signal circuits to a look up table stored in the PCM memory. PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic table.
Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A, B, C and Parity.
When the PCM detects an invalid TR switch signal combination, then DTC P0705 sets. DTC P0705 is a type C DTC.

From reading your post an my years of experince your best bet would be to take to a qualified repair shop . You do not have the knowlede or tool's to fix these problems .

Install a Scan Tool .
Turn ON the ignition, with the engine OFF.
Select TR Sw. on the Scan Tool .
With the Scan Tool , observe the TR Sw. display while selecting each transmission range: P, R, N, D3, D2 and D1.
Does each selected transmission range match the Scan Tool TR Sw. display?

I need the trouble code for a 1998 saab 900se turbo whats wrong the codes i have are p0133 and p0705 what does this mean


P0133
O2 Sensor Circuit Slow Response Bank 1 Sensor 1

P0705
Transmission Range Sensor "A" Circuit (PRNDL Input)

HI. Lets start with the P0133 Code:

This code is in reference to the O2 sensor that is behind the catalytic converter(down stream sensor). You will need to test the connecting harness that links that sensor to the ECM for shorts. If the harness is ok, simply, replace that sensor.I would also advise to check for any apparent exhaust leaks as well and for proper MAF functions. You will more than likely have to replace the sensor, but ti be safe, check the areas I have stated first before you replace it.

Now, lets move on to the next code. This will be the P0705:

This code is in reference to the park/neutral position switch circuit. The only recourse here will be to replace that switch. It has failed.

Check engine light is on. Is it the PO705 vehicle speed sensor A maken it do that?


Yup, if you scanned your engine computer and you got a code P0705, you can bet that's why your Check Engine light is on.

P0705, however, is NOT a Vehicle Speed Sensor code on this vehicle. It is a Digital Transmission Range Sensor code. It is caused by an open or shorted circuit in the TR-1, TR-2, TR-3a or TR-4 circuits. This code CANNOT be set by an incorrectly adjusted TR Sensor.
