DTC P0336: Range/Performance Problem in Crankshaft Position (CKP) Sensor Circuit




General Description
The crankshaft position (CKP) sensor detects the number of revolutions of the crankshaft and sends a pulsing signal to the powertrain control module (PCM). The PCM converts the pulsing signal into engine speed.

If the engine speed measured by the CKP sensor is lower than the value that is estimated based on the drive pulley speed, a malfunction in the CKP sensor is detected and a DTC is stored.

Enable Conditions

Malfunction Threshold
The engine speed measured by the CKP sensor is less than the drive pulley speed by a factor of 0.56 for at least 18 seconds.

Driving Pattern
1. Start the engine.
2. Shift to the D, S, L, or R positions, and wait for at least 30 seconds.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the PCM memory.

Conditions for clearing the MIL
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
