DIAGNOSTIC TROUBLE CODE (DTC) P0336 CRANKSHAFT POSITION (CKP)

SENSOR CIRCUIT RANGE/PERFORMANCE

D06RX122

Circuit Description

The 58X reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolution,
58 crankshaft pulses will be produced. The engine control
module (ECM) uses the 58X reference signal to calculate
engine RPM and crankshaft position. The ECM
constantly monitors the number of pulses on the 58X
reference circuit and compares them to the number of
camshaft position (CMP) signal pulses being received. If
the ECM receives an incorrect number of pulses on the
58X reference circuit, Diagnostic Trouble Code P0336 will
set. Diagnostic Trouble Code P0336 is a type B code.

Conditions for Setting the DTC

Engine is running.

Extra or missing pulse is detected between
consecutive 58X reference pulses.

Above condition is detected in 10 of 100 crankshaft
rotations.

Action Taken When the DTC Sets

The ECM will illuminate the malfunction indicator lamp
(MIL) after the second consecutive trip in which the
fault is detected.

The ECM will store conditions which were present
when the Diagnostic Trouble Code was set as Freeze
Frame and in the Failure Records data.

Conditions for Clearing the MIL/DTC

The ECM will turn the MIL OFF on the third consecutive
trip cycle during which the diagnostic has been run and
the fault condition is no longer present.

A history Diagnostic Trouble Code P0336 will clear
after 40 consecutive warm–up cycles have occurred
without a fault.

Diagnostic Trouble Code P0336 can be cleared by
using the Scan Tool’s ”Clear Info” function.

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; shorts to ground, shorts to battery positive
and open circuits. If the harness appears to be OK,
disconnect the ECM, turn the ignition on and observe
a voltmeter connected to the 58X 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 Diagnostic Trouble Code to

6E1–157

X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

be set occurs. This may assist in diagnosing the
condition.

Diagnostic Trouble Code P0337 is a type B code.

Conditions for Setting the DTC

No camshaft position (CMP) sensor DTCs are set.

Engine cranking.

Crankshaft position (CKP) sensor signal is not present
between two cam pulses.

CKP reference pulse is not detected within 24 CMP
pulses.
