How do you fix P0351?

How Is The P0351 Code Fixed?

  1. Replacing the ignition coil.
  2. Replacing the spark plug and spark plug wire.
  3. Repairing or replacing an ignition coil connector.
  4. Repairing any other electrical wiring or connector faults.
  5. Replacing the throttle body.
  6. Repairing or replacing the PCM.

What causes a P0351 code?

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.

What does P0351 mean?

Diagnostic Trouble Code (DTC) P0351 stands for “Ignition Coil ‘A’ Primary/Secondary Circuit.” It indicates that there’s a potential problem with the cylinder #1 ignition coil or its circuit.

Which cylinder is P0351?

The cylinder with the fault is indicated by the code’s last digit. As a result, P0351 is the code for cylinder 1 (ignition coil A), P0352 is the code for cylinder 2, P0353 is the code for cylinder 3 and so on.

What is primary and secondary ignition?

Ignition systems have two circuits that result in a spark being fired at the end of a spark plug. The primary circuit is between the battery and the ignition coil. The secondary circuit is between the ignition coil and the spark plug.

What is primary and secondary ignition coil?

What does ignition coil a secondary circuit mean?

The P2302 code means that the ignition coil A secondary circuit has experienced a malfunction. The malfunction is detected by the vehicle’s ECU when it tries to control the secondary ignition circuit. This causes a Check Engine Light to be illuminated on the dashboard and a failsafe mode to be enabled.

What is the primary ignition circuit?

Ignition system is divided into two electrical circuits – the primary and secondary circuits. The primary circuit carries low voltage. This circuit operates only on battery current and is controlled by the breaker points and the ignition switch. The coil is the heart of the ignition system.
