P0352

Diagnostic Chart:

Wiring Diagram:

The PCM controls dwell and spark timing during all engine running conditions. The electronic ignition (EI) module charges the coil pack when the PCM supplies 5 volts to the 2/3 coil. The coil will then discharge or fire through its secondary coil towers whenever the voltage supply has been turned Off by the PCM.

DTC PARAMETERS

During cranking the PCM pulses the ignition control (IC) circuit high and low. The PCM monitors the diagnostic feedback circuit to diagnose circuit faults.

DTC P0352 will set if there is an open, short to voltage or short to ground in IC 2 and 3 (circuit 406).

OR

DTC P0352 and P1352 will set if there is a short to voltage in IC 2 and 3 (circuit 406) when:

^ The engine is in cranking mode.

NOTE: IC circuit 2 and 3 is checked continuously whenever crankshaft position sensor pulses arc received by the PCM during cranking mode only.

DIAGNOSTIC AIDS

When attempting to diagnose an intermittent problem use the Scan tool to review malfunction history diagnostic information. The supplemental data can be used to duplicate a problem.

Intermittents or opens suspected to be at the connector can be detected by using diagnostic service probe. Voltage can be read on wire without disconnecting any connectors.

Check the tightness of the female terminal grip with a spare male terminal.

The IC circuit consists of an ignition module, circuit 406 and the PCM.

NOTE: If there is an open in the IC 2 and 3 circuit a misfire on those cylinders will occur.

^ A malfunctioning 2-3 coil, secondary wire or 2-3 spark plug will not cause a P0352 and/or P1352 to set.

^ A blown EIS fuse will cause a no start condition but a IC 2 and 3 DTC should not set. This fault will set a P0340 if the engine was cranked long enough.

^ A fault on the IC circuit while running will result in a misfire P0300 DTC.
