A : Ignition Coils P0351, P0352, P0353, P0354, P0355, P0356, P1367, P1368

NOTE: Unless multiple cylinder misfires are apparent, only one circuit will normally need to be tested. The DTC set will indicate which cylinder is misfiring.

A1 : CHECK COIL FUNCTION BY SUBSTITUTION

1. Swap suspect coil for known good unit.
2. CLEAR the DTC. TEST the system for normal operation.

Does the same DTC reoccur? The DTC will indicate if the same cylinder is misfiring.
Yes
Goto A2

No
CLEAR the DTC. TEST the system for normal operation.

A2 : CHECK THE IGNITION COIL SUPPLY VOLTAGE CIRCUIT

1. Disconnect the relevant A bank ignition coil electrical connector(s).
2. Turn the ignition switch to the ON position.
3. Measure the voltage between:
- Cyl A1. EN051 pin 1, (RW) and GROUND.
- Cyl A2. EN052 pin 1, (RW) and GROUND.
- Cyl A3. EN053 pin 1, (RW) and GROUND.
4. Disconnect the relevant B bank ignition coil electrical connector(s).
5. Measure the voltage between:
- Cyl B1. EN054 pin 1, (RW) and GROUND.
- Cyl B2. EN055 pin 1, (RW) and GROUND.
- Cyl B3. EN056 pin 1, (RW) and GROUND.

Is the voltage greater than 10.5 Volts?
Yes
Goto A3

No
REPAIR the relevant ignition coil supply voltage circuit. For additional information, refer to wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

A3 : CHECK THE IGNITION COIL GROUND CIRCUIT

1. Switch the ignition to the OFF position.
2. Disconnect the relevant A bank ignition coil electrical connector(s).
3. Measure the resistance between:
- Cyl A1. EN051 pin 3, (B) and GROUND.
- Cyl A2. EN052 pin 3, (B) and GROUND.
- Cyl A3. EN053 pin 3, (B) and GROUND.
4. Disconnect the relevant B bank ignition coil electrical connector(s).
5. Measure the resistance between:
- Cyl B1. EN054 pin 3, (B) and GROUND.
- Cyl B2. EN055 pin 3, (B) and GROUND.
- Cyl B3. EN056 pin 3, (B) and GROUND.

Is the resistance less than 5 ohms?
Yes
Goto A4

No
REPAIR the relevant ignition coil ground circuit. For additional information, refer to wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

A4 : CHECK THE CONTINUITY OF THE IGNITION COIL TRIGGER SUPPLY CIRCUIT


1. Disconnect the PCM electrical connector EN016.
2. Check the continuity of the ignition coil trigger supply circuit between the relevant ignition coil electrical connector(s) and the PCM electrical connector:
- Cyl A1. EN051 pin 4, (GU) and EN016 pin 87, (GU)
- Cyl A2. EN052 pin 4, (GW) and EN016 pin 88, (GW)
- Cyl A3. EN053 pin 4, (GR) and EN016 pin 89, (GR)
- Cyl B1. EN054 pin 4, (GU) and EN016 pin 61, (GU)
- Cyl B2. EN055 pin 4, (GW) and EN016 pin 62, (GW)
- Cyl B3. EN056 pin 4, (GR) and EN016 pin 63, (GR)

Is the resistance less than 5 ohms?
Yes
Goto A5

No
REPAIR the ignition coil trigger supply circuit between the relevant ignition coil electrical connector(s) and the PCM electrical connector. CLEAR the DTCs. TEST the system for normal operation.

A5 : CHECK THE CONTINUITY BETWEEN THE IGNITION COIL AND THE PCM

1. Check the continuity of the ignition coil diagnostic signal circuit, between the ignition coil electrical connector(s) and the PCM electrical connector:
- Cyl A1. EN051 pin 2, (YG) and EN016 pin 131, (YG)
- Cyl A2. EN052 pin 2, (YG) and EN016 pin 131, (YG)
- Cyl A3. EN053 pin 2, (YG) and EN016 pin 131, (YG)
- Cyl B1. EN054 pin 2, (YG) and EN016 pin 132, (YG)
- Cyl B2. EN055 pin 2, (YG) and EN016 pin 132, (YG)
- Cyl B3. EN056 pin 2, (YG) and EN016 pin 132, (YG)

Is the resistance less than 5 Ohms?
Yes
INSTALL a new PCM. For additional information refer to Before replacing a PCM, contact Dealer technical support. CLEAR the DTCs. TEST the system for normal operation.

No
REPAIR the circuit between the ignition coil electrical connector(s) and the PCM electrical connector. CLEAR the DTCs. TEST the system for normal operation.
