DIAGNOSTIC TROUBLE CODE (DTC) – P0337 58X CRANKSHAFT POSITION
SENSOR NO SIGNAL
Circuit Description
The 58X reference signal is produced by the crankshaft
position (CKP) sensor. During one crankshaft revolu-
tion, 58 crankshaft pulses will be produced. The engine
control module(ECM) uses the 58X reference signal to
calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference cir-
cuit and compares them to the number of camshaft posi-
tion (CKP) signal pulses being received. If the ECM
receive and incorrect number of pulses on the 58X refer-
ence circuit, DTC P0337 will set.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

No crankshaft teeth detected.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
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 con-
nectors for improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal-to-wire
connection.
Damaged harness – inspect the wiring harness for dam-
age. If the harness appears to be OK, disconnect the
ECM, turn the ignition ON and observe a voltmeter con-
nected to the 58X reference circuit at the ECM harness
connector while moving the connectors and the wiring
harness related to the ECM. A change in voltage will in-
dicate the location of the fault.
Review the failure records vehicle mileage since the
diagnostic test failed may help determine how often the
condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.

Engine is running.

No traction of CMP signal between teeth 18 and 82
but change in polarity.
Action Taken When the DTC Sets

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

Diagnostic Aids
Check and correct any abnormal engine noise before
using the diagnostic table.
Any circuitry that is suspected as causing engine noise
complaint should be thoroughly checked for the follow-
ing conditions :

Backed-out terminals.

DIAGNOSTIC TROUBLE CODE (DTC) – P1382 ROUGH ROAD DATA INVALID
(NON ABS)
Circuit Description
The VR sensor is used to detecting the road situation.
By sensing difference of wheel rotation duration caused
by bumps or potholes in the road, the Engine Control
Module (ECM) can determine if the changes in crank-
shaft speed are due to engine misfire or are driveline in-
duced. If the VR sensor detects a rough road condition,
the ECM misfire detection diagnostic will be de-acti-
vated.
The VR sensor is located in front–right wheel.
Conditions for Setting the DTC

Vehicle speed is higher than 10km/h(6.21mph).

No Vehicle Speed Sensor error not set.

VR sensor output signal is higher than 0.26.
VR sensor output signal is not change for 30seconds.
Action Taken When The DTCs Sets

The Malfunction Indicator Lamp (MIL) will not illumi-
nate.

The ECM will store conditions which were present
when the DTC was set as Failure Records data only.

This information will not be stored in the Freeze
Frame data.
Conditions for Clearing the MIL/DTC

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

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.
