DIAGNOSTIC TROUBLE CODE (DTC) P0335
CRANKSHAFT POSITION SENSOR MALFUNCTION
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
Position (CMP) signal pulses being received. If the ECM
receives and incorrect number of pulses on the 58X
reference circuit, Diagnostic Trouble Code (DTC) P0335
will set.
Conditions for Setting the DTC
•••••
Error counter of undetected gap is greater than 40.
•••••
The number of camshaft signals while no crankshaft
signal is greater than 5.
•••••
The change of adaptation value is greater than
0.08 % for 2.3L DOHC and greater than 0.5 % for
3.2L DOHC. (every driving cycle after end of line)
•••••
The change of adaptation value is greater than
1.6 %. (first driving cycle at end of line)
•••••
DTC P0336 is not set.
•••••
Coasting shut down is active.
•••••
Engine speed is between 1800 and 5010 rpm
(2.3L DOHC).
•••••
Engine speed is between 1500 and 4200 rpm
(3.2L DOHC).
•••••
Engine speed is difference between consecutive
revolutions is less than 7 rpm for 2.3L DOHC and
less than 8 rpm for 3.2L DOHC.
•••••
Brake is not active.
Action Taken When the DTC Sets
•••••
The Malfunction Indicator Lamp (MIL) will illuminate
after two consecutive driving cycles in which the diag-
nostic runs with the fault active.
•••••
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 three consecutive driving
cycles in which the diagnostic runs without a fault.
•••••
A history DTC will clear after 40 consecutive warm-
up cycles without a fault.
•••••
The 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 connections.
•••••
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 voltme-
ter connected to the 58X reference circuit at the ECM
harness connector while moving the connectors and
the wiring harnesses related to the ECM.
