1F – 152 ENGINE CONTROLS
DIAGNOSTIC TROUBLE CODE (DTC) – P0336 58X CRANKSHAFT POSITION
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 P0336 will set.
Conditions for Setting the DTC
D This DTC can be stored in "key-on" status.
D Detected number of teeth is differs by 3 or higher.
Action Taken When the DTC Sets
D The Malfunction Indicator Lamp (MIL) will illuminate.
D 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.
D A history DTC is stored.
Conditions for Clearing the MIL/DTC
D The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
SENSOR NO PLAUSIBLE SIGNAL
D A history DTC will clear after 40 consecutive warm-up
cycles without a fault.
D DTC(s) can be cleared by using the scan tool.
D Disconnecting the ECM battery feed for more than 10
seconds.
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.
