Manual, please make a reference to this bulletin on the affected page.
Circuit Description
The crankshaft position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor circuits are connected directly to the
powertrain control module (PCM) and consists of the following circuits:
^
The 12-volt reference circuit
^
The low reference circuit
^
The CKP sensor signal circuit
If the PCM detects that the CKP sensor signal is inconsistent for 2 seconds, DTC P0336 sets.
Conditions for Running the DTC
The engine is cranking or running.
Conditions for Setting the DTC
The PCM detects that the CKP sensor signal is inconsistent for 2 seconds.
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 conditions 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.
