Diagnostic Trouble Code (DTC) P0337 CKP Sensor Circuit Low Frequency
060R200066
Circuit Description
The 58X reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolution,
58 crankshaft reference pulses will be produced. The
powertrain control module (PCM) uses the 58X reference
signal to calculate engine RPM and crankshaft position.
The PCM constantly monitors the number of pulses on
the 58X reference circuit. If the PCM does not receive
pulses on the 58X reference circuit, DTC P0337 will set.
Conditions for Setting the DTC

Engine cranking.

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

CKP reference pulse is not detected within 8 CMP
pulses.
Action Taken When the DTC Sets

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

The PCM 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

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

A history DTC P0337 will clear after 40 consecutive
warm-up cycles have occurred without a fault.

DTC P0337 can be cleared by using the Tech 2 ªClear
Infoº function or by disconnecting the PCM 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 PCM 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, disconnectthe PCM, turn the ignition on and observe a voltmeter
connected to the 58X reference circuit at the PCM
harness connector while moving connectors and
wiring harnesses related to the PCM. 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.
