DTC Advanced Diagnostics: P0351, P0352, P0353, P0354

DTC P0351:No. 1 Cylinder Ignition Coil Circuit Malfunction
DTC P0352:No. 2 Cylinder Ignition Coil Circuit Malfunction
DTC P0353:No. 3 Cylinder Ignition Coil Circuit Malfunction
DTC P0354:No. 4 Cylinder Ignition Coil Circuit Malfunction

General Description

The ignition coil is triggered at the optimum time by the powertrain control module (PCM) ON/OFF command. The PCM detects a malfunction when the engine is running and the return signal does not change for a specified time, the PCM detects a malfunction and stores a DTC.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
