DTC P0351, P0352, P0353, P0354 (K20C1) (2017 2018 2019)

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 

Courtesy of HONDA, U.S.A., INC.

Electrical errors in connections from the ignition driver to the ignition coils could be detected by the powertrain control module (PCM) internal circuit. The PCM identifies short circuits and open circuit. The diagnosis of lines are done every 2 rotations of crankshaft. If the ignition coil output is out of a normal range, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold 

• Short circuit to ground

  The ignition coil output current exceeds 30 mA for at least 0.5 second.

• Short circuit to power

  The ignition coil output voltage exceeds 5 V for at least 0.5 second.

• Open

  The ignition coil output current drops below 1 mA for at least 0.5 second.

Possible Cause 

NOTE:  The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

DTC: P0351

• No. 3 ignition coil IGN03 line open

DTC: P0354 

• No. 4 ignition coil IGN04 line short to ground
• No. 4 ignition coil IGN04 line short to power
• No. 4 ignition coil IGN04 line open

Common 

• Ignition coil internal circuit failure
• PCM internal circuit failure

Confirmation Procedure 

Operating Condition 

Start the engine, and let it idle.

With the HDS 

None.

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.
