Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. The powertrain control module PCM monitors the fuel enable signal during crank.
If the proper signal is present on the theft deterrent fuel enable circuit, the PCM enables fuel delivery to allow the engine to start. DTC P can cause a no-start condition or normal operation depending on when the loss of the fuel enable signal was detected. The engine will continue to start and run if the condition that set DTC P occurred after the BCM sensed the proper key resistor pellet and signaled the PCM to continue fuel delivery.
The engine will start and immediately stall if the condition that set DTC P occurred before the BCM sensed the proper key resistor pellet.

Brief explanation of the P code and definition of P is the bottom side.
MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults.
There are currently two main types of cylinder deactivation used today, depending on the type of engine. P code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed.
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. When you see P engine fault code on your engine code reader this description will help you. Final Step: In the definitions listed below, there is a test drive recommended after you've completed any repairs to see if the condition is fixed.
Before you take a test drive after a repair, always erase the P Code s first. This will turn the check engine light off and then you will know if the check engine light returns, you've got further diagnostics to complete.

Example: P How To Fix P?I have code how do fix this? Please help me I love this site. Do you. This can be from a faulty BCM which is common in these cars. Here is some information from the book: DTC P Circuit Description: The body control module BCMproduces the theft deterrent crank relay and fuel enable signal when ignition is ON and the proper ignition code voltage value is detected.
The powertrain control module PCM monitors the fuel enable signal during crank. If the proper signal is present on the class 2 serial data circuit, the PCM enables the fuel delivery in order to allow the engine to start. The engine continues to start and run as long as DTC P is stored. This information will not be stored as freeze frame data. The DTC can be cleared by using a scan tool.
Try to disconnect the battery for ten minutes and then reconnect it to see what happens it could reset. If the problem then returns the BCM is bad here is its location you will need a shop to program it for you. Below Let me know Cheers Image Click to enlarge.
P1626 Engine Fault Code
Was this answer. I had to replace transmission on this car. So I move the engine so I can get to transmission and got it back together and know it will not start by key to start. All it will do is no sound from starter. It will start is if I go under car it will run about four seconds and shut off. So I put my snap on scanner on it it has codeu, code is theft deterrent system fuel is disable u How do I get it running?
Is there a way to get it running by key learning? I have tried key in for ten minutes and pull key out for less then twenty seconds and do it again. Is there something I am missing or is there a way I can bypass the system?P engine code seems a kind of powertrain problem, we try to show one by one the meaning and the solution.
Brief explanation of the P code and definition of P is the bottom side. MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults.
The original multi-displacement system turned off opposite pairs of cylinders, allowing the engine to have three different configurations and displacements. P code had an elaborate diagnostics procedure, including showing engine trouble codes on the air conditionning display. However, the system was troublesome, misunderstood by customers, and a rash of unpredictable failures led to the technology being quickly retired. Regarding the P code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket.
This is done most easily from below the car in the area near the oil filter. When you see P engine fault code on your engine code reader this description will help you.

This is not intended as repair advice and we are not responsible for any actions you take on any vehicle. Example: P How To Fix P?Theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. So you should chech it on our car models.
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.
If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. Parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

Now don't ask yourself; What should you do with P code? The solution is here :.GM made several different types of anti-theft systems. The troubleshoot and reset procedures are different for each. PassLock seems to have the highest failure rate.
This article describes how to troublshoot and fix a PassLock system. But here are some more articles to help. Click here to see the resetting procedure for PassLock. Click here to see the trouble codes for a PassLock system.
Click here to see a typical PassLock wiring diagram. The BCM sets this code if it sees a short to ground on the Passlock sensor power circuit white wire for one second. The engine will not start or will start and stall. Next time you restart the BCM will send a password to the PCM to allow fuel injector operation and the engine will start. This is basically a short to battery from the sensor supply circuit white wire to the sensor circuit yellow wire.
The BCM will set this code if it detects sensor voltage yellow wire of less than.
This is usually a sign of a poor connection. After you fix the connection, wait mins for the tamper timer to expire. The BCM will not allow the vehicle to start if it detects low voltage before you start the vehicle. The BCM will set this code if it sees signal input voltage yellow wire higher than 4.
The BCM will enter fail enable mode and will allow the engine to start and run. The code will clear once the BCM senses normal voltage, but will store the code as a history code for the next concurrent ignition cycles. The BCM is expecting a certain voltage value from the sensor based on its last learn cycle. If the BCM sees a different voltage value from the sensor, it will not send a coded message to the PCM and the vehicle will not start.
A new BCM is programmed to accept the first voltage value it sees from the sensor, providing that the value is within limits.99 Safari passlock control module location
The BCM will set this code if it is in learn mode but does not see a valid sensor voltage yellow wire. The BCM sets this code when it sees a voltage signal from the sensor yellow wire indicating a tamper situation during engine startup.
It will send a message to the PCM to disable fuel delivery. The BCM will then stop sampling sensor readings for mins.
