Diagnostic Trouble Code (DTC) Information ECM-330B

Condition 

If there is no signal from the engine speed (RPM) sensor or if its signal is lower than the engine speed signal from the camshaft position (CMP) sensor, the engine control module (ECM) interprets this as a fault and the diagnostic trouble code (DTC) is stored.

The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Substitute Value 

The engine control module (ECM) uses the signal from the camshaft position (CMP) sensor if the camshaft position (CMP) sensor has been adapted.

Possible Source 

• Open-circuit in the signal cable or ground lead
• Short-circuit to ground or supply voltage in the signal cable
• Contact resistance in the terminals
• Damaged engine speed (RPM) sensor
• Damaged carrier plate.

Fault symptom[s] 

• The engine does not start
• The engine stops.
