DIAGNOSTIC TROUBLE CODE (DTC) P0300
MULTIPLE CYLINDER MISFIRE (CATALYST DAMAGE)
System Description
The Engine Control Module (ECM) monitors the crank-
shaft and camshaft positions to detect if the engine is mis-
firing. The ECM looks for a quick drop in crankshaft speed.
This test is executed in blocks of 200 engine revolution
tests. It may take between one to several tests to store a
Diagnostic Trouble Code (DTC), the Malfunction Indicator
Lamp (MIL). Severe misfire will flash the MIL, indicating
that catalyst damage is possible.
Conditions for Setting the DTC
S The engine speed is less than 4,500 rpm.
S The fuel tank level is greater than 20%.
S No anti–jerk correction.
S No rough road detection.
S No crankshaft oscillation detection.
S DTCs P0107, P0108, P0122, P0123, P0341,
P0342, P0336 and P0337 are not set.
Action Taken When the DTC SetsS The malfunction Indicator Lamp (MIL) will blinking.
S The ECM will record operating conditions at the
time the diagnostic fails. The information will be
stored in the Freeze Frame and Failure Records
buffers.
S A history DTC is stored.
Conditions for Clearing the MIL/DTC
S A history DTC will clear after 40 consecutive warm
up cycles without a fault.
S DTC(s) can be cleared by using the scan tool.
S Disconnecting the ECM battery feed for 10 sec-
onds.
Diagnostic Aids
An intermittent can also be the result of a defective reluctor
wheel. Remove the CKP sensor and inspect the reluctor
wheel through the sensor mount hole. Check for porosity
and the condition of wheel. If the DTC is intermittent refer
to ”Symptoms Diagnosis” in this section.

DIAGNOSTIC TROUBLE CODE (DTC) P0335
MAGNETIC CRANKSHAFT POSITION SENSOR
ELECTRICAL ERROR
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 transaxle con-
trol module(TCM)/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 circuit and compares them to the number
of camshaft position (CKP) signal pulses being received.
If the ECM receive and incorrect number of pulses on the
58X reference circuit, DTC P0335 will set.
Conditions for Setting the DTC
S The magnetic crankshaft position sensor is greater
than 0.2V.
Or
S The minimum value of magnetic crankshaft position
sensor is less than 1.5V.
Or
S The maximum value of magnetic crankshaft posi-
tion sensor is higher than 2.2V.
Action Taken When the DTC Sets
S The Malfunction Indicator Lamp (MIL) will illuminate
after three consecutive trip with a fail.
S The ECM will record operating conditions at the
time the diagnostic fail. This information will be
stored in the Freeze Frame and Failure Records
buffers.S A history DTC is stored.
Conditions for Clearing the MIL/DTC
S The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
S A history DTC will clear after 40 consecutive warm–
up cycles without a fault.
S DTC(s) can be cleared by using the scan tool.
S 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 connec-
tors for improper mating, broken locks, improperly formed
or damaged terminals, and poor terminal–to–wire connec-
tion.
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 har-
ness related to the ECM. A change in voltage will indicate
the location of the fault.
Review the failure records vehicle mileage since the diag-
nostic test failed may help determine how often the condi-
tion that caused the DTC to be set occurs. This may assist
in diagnosing the condition.
