P0351 is a general OBD2 diagnostic trouble code (DTC) that points to a fault with the ignition coil A.
The P0351 DTC is seen when the ignition coil A primary or secondary circuit has a malfunction. The engine control module is looking for specific signals from the ignition coil A and when these signals are not seen the ECU sets the Check Engine Light. The Check Engine Light will be illuminated on the dashboard.
Uses a scanner to check what codes are stored in the ECU, along with any freeze frame data for the codes
Clears the codes and test drives the vehicle under similar conditions found in the freeze frame data to best duplicate the faults
Performs a visual inspection on the coil system and it's wiring, looking for any damaged or worn components
Uses scan tool to monitor he data stream information and determine if the fault is with a specific cylinder or all of the cylinders
Inspects the spark plug wire and plug, or the coil pack of the vehicle if the fault is with just one cylinder
Tests the primary ignition coil for proper operation if all of the cylinders are faulty
Tests the ECU if no fault is found up until this point
Mistakes are made when components are replaced without being test or all steps are not followed completely in the proper order. This wastes time and money for repairs.
The P0351 code can have some drivability symptoms that will not make it safe to drive depending on how severe the symptoms are. This code should not prevent the vehicle from being able to be driven to a safe location but should still be repaired ASAP for normal vehicle operation.
The ability to view the live data stream of the vehicle is very important for the success of diagnosing the P0351 code. This aids technicians is finding intermittent faults that they would otherwise have no ability to noticed.
