Diagnostic Trouble Code (DTC) P0336 (Flash DTC 43)
CKP (Crank Position) Sensor Out of Synchro
060RW133
Circuit Description
The CKP reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolution,
crankshaft pulses will be produced. The Engine Control
Module ECM uses the CKP reference signal to calculate
engine RPM and crankshaft position. If the ECM receives
an incorrect number of pulses on the CKP reference
circuit, DTC P0336 will set.
Action Taken When the DTC Sets
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0336 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed–through wire insulation or a wire broken inside the
insulation. Check for:
Poor connection – Inspect the ECM harness and
connectors for improper mating, broken locks,
improperly formed or damaged terminals, and poor
terminal-to-wire connection.
Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, disconnect
the ECM, turn the ignition on and observe a voltmeter
connected to the CKP reference circuit at the ECM
harness connector while moving connectors and
wiring harnesses related to the ECM. A change in
voltage will indicate the location of the fault.
Reviewing the Failure Records vehicle mileage since the
diagnostic test last failed may help determine how often
the condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.

Diagnostic Trouble Code (DTC) P0341 (Flash DTC 41)
CMP (Cam Position) Sensor Out of Synchro
060RW133
Circuit Description
The CMP signal is produced by the camshaft position
(CMP) sensor pulses when the engine is running and
crankshaft position (CKP) sync pulses are also being
received. The Engine Control Module ECM uses the
CMP signal pulses to initiate sequential fuel injection. If
the ECM receives an incorrect number of pulses on the
CMP reference circuit, DTC P0341 will set.
Action Taken When the DTC Sets
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0341 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed–through wire insulation or a wire broken inside the
insulation. Check for:
Poor connection — Inspect the ECM harness and
connectors for improper mating, broken locks,improperly formed or damaged terminals, and poor
terminal-to-wire connection.
Damaged harness — Inspect the wiring harness for
damage. If the harness appears to be OK, disconnect
the ECM, turn the ignition on and observe a voltmeter
connected to the CMP signal circuit at the ECM
harness connector while moving connectors and
wiring harnesses related to the ICM and the CMP
sensor. A change in voltage will indicate the location
of the fault.
