P0350 - Ignition Coil Primary/Secondary Circuit Description: Each ignition primary circuit is continuously monitored. The test fails when the powertrain control module (PCM) does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module (integrated in the PCM). Possible Causes:
  • Open or short in the Ignition START/RUN circuit
  • Open coil driver circuit
  • Coil driver circuit shorted to ground
  • Damaged coil
  • Coil driver circuit shorted to VPWR
Diagnostic Aids: Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector.
Check the coil driver circuit for open, short to VPWR, or short to ground. Application Key On Engine Off Key On Engine Running Continuous Memory Coil pack ignition testing GO to Pinpoint Test JC .

How to reset Theft Deterrent fuel enable signal


have you put obd11 scanner on it to find error code.
DTC P1626 Theft Deterrent Fuel Enable Signal Lost
Circuit Description
The Vehicle Theft Deterrent (VTD) system is incorporated within the body control module (BCM). The powertrain control module(PCM) monitors the state of health serial data message from the Theft Deterrent system to ensure that the PCM to BCM communications is established. If the PCM detects a loss of the state of health message while the engine is running, DTC P1626 will set. DTC P1626 can cause a no-start condition or normal operation depending on when the loss of Theft Deterrent system communication was detected. The engine will continue to start and run if the condition that set DTC P1626 occurred after the PCM received a valid theft deterrent password from the BCM and already allowed fuel during the ignition cycle. The engine will start and immediately stall if the condition that set DTC P1626 occurred before the PCM received a valid theft deterrent password. With this condition present, the PCM will inhibit fuel delivery and disable the starter until a valid theft deterrent password is detected. Refer to Content Theft Deterrent (CTD) Circuit Description .

Conditions for Running the DTC
The Theft Deterrent system has allowed fuel delivery.
Conditions for Setting the DTC
The PCM has detected a loss of the state of health serial data message from the Theft Deterrent system.

Action Taken When the DTC Sets
The PCM stores conditions which were present when the DTC set as Failure Records only. This information will not be stored as Freeze Frame Records.

Conditions for Clearing the MIL/DTC
The DTC becomes history when the conditions for setting the DTC are no longer present.
The history DTC clears after 40 malfunction free warm-up cycles.
The PCM receives a clear code command from the scan tool.
Diagnostic Aids,
An intermittent may be caused by:

• A poor connection

• Rubbed through wire insulation

• A wire broken inside the insulation

Check for the following conditions:, • Intermittent short circuit on the serial data circuit -- Refer to Data Link Communications Operation in Data Link Communications. Be sure to check all related wiring for an intermittent short to ground or short to voltage.

• Poor connection -- Inspect the wiring harness for damage. Check for an intermittent short or open circuit in the wiring harness related to the BCM, including the ignition, battery feed, ground, and Serial Data circuits.

Nissan pathfinder 2004 turbo diesel trouble code p1275


This answer is coutesy of expert ZL Limited

DTC P1275 - Acceleration Position Sensor 1 Circuit Malfunction
The acceleration position (AP) sensor circuit provides a voltage signal relative to acceleration pedal angle. The acceleration pedal angle (AP1) will vary about 13% at idle position to about 87% at wide open throttle (WOT). This code detects a continuous short to ground or high in either the circuit or the sensor.

9_4_2012_8_23_06_pm.gif
Conditions for setting the DTC:
* The Ignition is "ON".
* The acceleration pedal angle is less than 2.5% or more than 97% for 12 counts within 500 test samples (15.6 m sec ).

Action Taken When the DTC Sets:
* The PCM will store condition which were present when the DTC was set as Freeze Frame and in the Failure Records data.

Conditions for Clearing the MIL/DTC:
* The PCM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
* A history DTC P1275 will clear after 40 consecutive trip cycle during which the warm up cycles have occurred without a fault.
* DTC P1275 can be cleared using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed.

9_4_2012_8_23_55_pm.gif

Diagnostic Aids
An intermittent may be caused by the following:
* Poor connections.
* Mis routed harness.
* Rubbed through wire insulation.
* Broken wire inside the insulation.

Check for the following conditions:
* Poor connection at PCM-Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
* Damaged harness-Inspect the wiring harness for damage. If the harness appears to be OK, observe the APP sensor 1 display on the Tech 2 while moving connectors and wiring harnesses related to the sensor.

A change in the display will indicate the location of the fault. If DTC P1275 cannot be duplicated, the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set.

If it is determined that the DTC occurs intermittently, performing the DTC P1275 Diagnostic Chart may isolate the cause of the fault.

Oldsmobile Silhouette 1998 Error code: P0341 Engine light on... Error code P0341 on auto scanner tool suggests "Camshaft Sensors" Does this vehicle have 2 x camshaft sensors? Locations for...


DTC P0341 will set if Camshaft Position (CMP) sensor pulses are not in proper ratio to 24X and 3X Crankshaft Position (CKP) pulses.

Conditions required to set this DTC are:

> Engine running and PCM is receiving valid 3X reference pulses
> CMP reference pulse signal is not detected on every engine cycle
> Condition is present for at least 30 seconds

The first thing that should be done is visual inspection of the wiring harnesses to the sensors and the secondary ignition cables and coil packs. Please note that misrouted spark plug cables an/or cracked and arcing ignition coils can cause interference with the CMP and CKP circuits. Inspect to be certain that the ignition cables are correctly routed and fastened in their original holders (or equivalent). Also check for deteriorated wire coverings (wire loom) leading to the CMP, 3X , and 24X sensors. If there are problems found, repair as necessary and retest vehicle.
If there are no problems as listed above, the next step is to determine if this is a "Current" (hard-fault) or an "history" (intermittent fault).

If your scanner has the capability of outputting computer data, check the codes under "current codes" or "failed this ignition". If the code is there, then the problem is occurring "RIGHT NOW"! This can make the problem much easier to find. (We'll get to that later) If the code is only in "continuous memory" Then the problem is intermittent. For intermittent faults, it would be best to return to the top of this post and re-check everything - also pull and tug on wires and harnesses to see if you can get the code to set.

If your scanner does not have this capability (outputs generic OBD codes only) Then the easiest way to determine if it is a hard fault is to clear the codes, then start the engine and run it for about 2 minutes and check codes again. If the code set after 2 minutes, then it can be considered a hard fault. Let me know if the problem is a hard fault and we'll walk through checking the circuits. Again, for intermittent faults, try wiggle-testing and checking components over - see if you can get the code to set. Check codes between everything you pull on or wiggle so you can determine which part of the system has the problem. (If you wiggle and pull EVERYTHING before rechecking codes and the code sets, you have not eliminated ANYTHING.)

Please also refer to the picture to help with understanding the components involved.

I have a 02 dodge grand caravan sport with 0351,0352,0700 codes...car runs good then shakes and even stalls at times,but not all the time...i have replaced ignition coil,wires,plugs,and catalytic...


Do you mean P0351, P0352, P0700? (The "P" makes a HUGE difference - it could also be a "C" a "B" or a "U") When you post fault codes, please be sure to post the ENTIRE fault code.

Anyway, P0700 is a generic code that is output by the Engine Control Module (ECM) to let you know that there are transmission faults present in the Transmission Control Module (TCM). To find out what the problem actually is, you must have a scanner that is capable of accessing the TCM and retriving the codes. NOTE: a "generic OBD" code reader cannot do this.

P0351 is "Ignition Coil #1 Primary Circuit"
P0352 is "Ignition Coil #2 Primary Circuit"

The ignition coil primary circuit is monitored when battery voltage is more than 8 volts during cranking or more than 13 volts with the engine running at less than 3000 RPM, and no coil in dwell during testing. The Diagnostic Test Code (DTC) will set in the Powertrain Control Module (PCM) memory when the PCM senses peak current is not achieved with battery based dwell plus 1.5 milliseconds of diagnostic offset. DTC P0351 and/or DTC Po352 takes less that 3 seconds to set during engine cranking, or up to 6 seconds with the engine running. Possible causes for these DTCs are : Intermittent condition, defective ignition coil (or coils), defective connectors or wiring,defective PCM .

NOTE: Intermiitent failures or problems in the contacts/circuits of the Auto Shutdown (ASD) relay can also cause these codes. Some aftermarket equipment , like remote starters and antitheft systems that are connected to the ASD relay circuits can also cause these codes. Any such equipment should be COMPLETELY removed from the vehicle before attempting to diagnose these codes.

What this code is p-1784


P1784-LR PRESSURE SWITCH SENSE CIRCUIT
This is a transmission fault code. Diagnosing it will require the DRB3 scan tool, or equivalent aftermarket scanner, and the transmission simulator tool.
---------------
Remove the VB(valve body) and the solenoid pack is easy to change and a shift kit comes with a non stick switch valve.In most of the cases is faulty solenoid pack causing this eror code.But there are other possibilities to.
P1784-LR PRESSURE SWITCH SENSE CIRCUIT

When Monitored and Set Condition:
P1784-LR PRESSURE SWITCH SENSE CIRCUIT

When Monitored: Whenever the engine is running.

Set Condition: The appropriate code is set if one of the pressure switches are open or closed at the wrong time in a given gear.

POSSIBLE CAUSES
LOSS OF PRIME P1791 PRESENT.

I have a code po354 on my 99 expedition, book says cylinder d misfire, which cylinder is this?


I just worked on 98 expedition 5.4l had code PO354. This code refer to an open primary coil winding, open wire, or bad PCM.
Check primary winding with ohm meter should be from 0.5 to 1.5 ohms and about 2.5 ohms with a hot engine. check wiring with a noid light, run the engine and shake the harness if light goes out repair harness you should have battery voltage with key on the computer controls the ground side.
