P1351 Fault Code

BMW – MISFIRE CYLINDER 5 WITH FUEL CUTOFF

For BMW, P1351 is logged when the powertrain control module (PCM) has detected a misfire in cylinder 5 of the engine.

A misfire can be caused by a wide array of issues. Anything that can disrupt the required combination of air, fuel, and heat within the engine can be the culprit.

It is important to look for fault codes that can help further determine where the problem is based to allow for faster repairs.

BMW engines will typically cut off fuel to the cylinder that is misfiring to prevent further damage to various components.

Ford – IGNITION DIAGNOSTIC MONITOR CIRCUIT INPUT FAULT

For Ford, P1351 is logged when the powertrain control module (PCM) has detected an issue with the ignition diagnostic monitor circuit. This happens when the signal from the ignition diagnostic monitor is either lost or is outside of the allowable range.

This indicates that the ignition diagnostic monitor may be malfunctioning, which means the PCM is unable to accurately determine the operation of the ignition system.

The ignition diagnostic monitor is connected to the ignition module that controls the ignition coils when starting the vehicle.

When the ignition diagnostic monitor has a fault like this, it cannot properly relay signals between the PCM and the ignition system.

This can result in the vehicle being unable to start or struggling to start.

Fixing this can be similar to an issue with the ignition coil circuit itself. However, the focus should be directed on the diagnostic monitor itself.

Lexus – VVT SENSOR RANGE/PERFORMANCE PROBLEM (BANK 2)

For Lexus, P1351 is logged when the powertrain control module (PCM) has detected an issue with the variable valve timing (VVT) sensor in bank 2 of the engine.

The VVT sensor is responsible for monitoring the intake VVT solenoid, which controls the engine speed and load under certain conditions.

If the sensor is sending a signal that is outside of the allowable range, it is likely faulty. This can result in the PCM being unable to determine if the VVT solenoid is functioning properly.

Bank 2 refers to the side of the engine opposite to the location of the first cylinder. This only applies to engines that have multiple banks like a V-shape engine.

Chrysler – IGNITION DIAGNOSTIC MONITOR SIGNAL LOST TO PCM OR OUT OF RANGE

For Chrysler, P1351 is logged when the powertrain control module (PCM) has detected an issue with the ignition diagnostic monitor circuit. This happens when the signal from the ignition diagnostic monitor is either lost or is outside of the allowable range.

This indicates that the ignition diagnostic monitor may be malfunctioning, which means the PCM is unable to accurately determine the operation of the ignition system.

The ignition diagnostic monitor is connected to the ignition module that controls the ignition coils when starting the vehicle.

When the ignition diagnostic monitor has a fault like this, it cannot properly relay signals between the PCM and the ignition system.

This can result in the vehicle being unable to start or struggling to start.

Fixing this can be similar to an issue with the ignition coil circuit itself. However, the focus should be directed to the diagnostic monitor itself.
