P0335

CIRCUIT DESCRIPTION
The Crankshaft Position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor is connected directly to the Powertrain Control Module (PCM), and consists of the following circuits:
^ The 12-volt reference circuit
^ The low reference circuit The CKP sensor signal circuit

CONDITIONS FOR RUNNING THE DTC
^ DTC P0101, P0102, P0103, or P0341 are not set.
^ The Camshaft Position Sensor (CMP) is transitioning.
^ The Mass Airflow (MAF) is more than 3 g/s in Crank mode.
^ The MAF is more than 5 g/s in Run mode.

CONDITIONS FOR SETTING THE DTC
The CKP sensor signal is not detected for more than 3 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The control module illuminates the Malfunction Indicator Lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
^ The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The control module turns OFF the Malfunction Indicator Lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
^ A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
^ Use a scan tool in order to clear the MIL and the DTC.

TEST DESCRIPTION

Steps 1-5:

Steps 6-16:

The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if the DTC P0336 is an intermittent.
3. This step checks the ignition 1 voltage circuit to the crankshaft position sensor.
4. This step checks the crankshaft position sensor low reference circuit.
5. This step checks the crankshaft position sensor.
