P1362
DTC P1362CIRCUIT DESCRIPTION
The ignition control module (ICM) has independent power and ground circuits. The circuits between the ICM and the powertrain control module (PCM) consists of the following circuits:
- The ignition control (IC) timing signal
- The IC timing control
- The low resolution engine speed signal
- The medium resolution engine signal
- The camshaft position signal
- The low reference
Both the camshaft position (CMP) sensor and crankshaft position (CKP) sensor signals are input directly to the ICM. The ICM sends 3X signals to the PCM and controls the timing advance during engine cranking. The timing advance changes to PCM control after the following actions occur:
- The PCM receives the second 3X signal
- The PCM applies 5 volts to the IC timing signal circuit
If the PCM detects a short to voltage in the IC timing signal circuit, DTC P1362 sets.
CONDITIONS FOR RUNNING THE DTC
The engine is running.
CONDITIONS FOR SETTING THE DTC
The PCM detects a short to voltage in the IC timing signal circuit.
ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating condition at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
CONDITIONS FOR CLEARING THE MIL/DTC
- The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.
