All GO to Pinpoint Test DR.

P0349 - Camshaft Position Sensor A Circuit Intermittent (Bank 2)

Description: This DTC sets when the CMP21 circuit signal is intermittent. For additional camshaft position (CMP) sensor

location information, refer to Section 1, Engine Control Components.

Possible Causes: • Intermittent open circuit

• Intermittent short circuit

• Camshaft timing incorrectly set

• Camshaft position sensor trigger wheel out of alignment

• Damaged CMP sensor shielding

• Incorrect harness connections

• Corrosion

• Damaged camshaft position bank 2 sensor 1 (CMP21)

Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have

an intermittent impact on the CMP signal.

P0351 - Ignition Coil A Primary/Secondary Circuit

Description: This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the

ignition module PCM.

Possible Causes: • VPWR circuit open

• VPWR circuit short to ground

• COP1 circuit open (COP)

• CDA circuit open (coil pack)

• COP1 circuit short to voltage (COP)

• CDA circuit short to voltage (coil pack)

• COP1 circuit short to ground (COP)

• CDA circuit short to ground (coil pack)

• Damaged COP (if equipped)

• Damaged coil pack (if equipped)

Diagnostic Aids: The DTC P0351 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not

set the DTC P0351. The DTC P0301 does not set for a coil primary circuit malfunction. The DTC P0351 may set with or without the DTC P0301, however the DTC P0351 sets first. When this DTC is set, the PCM enters failure mode effects management (FMEM) which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present. If a primary coil is damaged due to a harness short to ground the PCM will not be damaged. Do not replace the PCM without verifying the coil driver functionality. Use the 12 volt non-powered test lamp to verify VPWR voltage at the ignition coil harness connector. Check the coil driver circuit for open, short to voltage, or short to ground.

P0352 - Ignition Coil B Primary/Secondary Circuit

Description: This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the

ignition module PCM.

Possible Causes: • VPWR circuit open

• VPWR circuit short to ground

• COP2 circuit open (COP)

• CDB circuit open (coil pack)

• COP2 circuit short to voltage (COP)

• CDB circuit short to voltage (coil pack)

• COP2 circuit short to ground (COP)
