Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P033500

Condition




The signal sent by the engine speed sensor to the engine control module (ECM) provides information on the number of teeth in the flywheel/number of holes in the carrier plate that has passed the engine speed sensor. The control module uses the signal to calculate engine speed. The diagnostic code is generated if via the engine speed sensor signal the control module detects an incorrect number of teeth on the flywheel/holes in the carrier plate for a certain number of crankshaft revolutions.
The diagnostic trouble code can be diagnosed by the control module when the starter motor is running.

Substitute value
- Signal from the camshaft position sensor.

Possible source
- The signal cable (+) has an open-circuit or is short-circuited to ground or supply voltage.
- The signal cable (-) has an open-circuit or is short-circuited to ground or supply voltage.
- Damaged engine speed (RPM) sensor

Fault symptom[s]
- Nothing.
