Diagnostic trouble code (DTC) information

Condition 

Diagnostic trouble code (DTC) ECM-3000 covers the exhaust camshaft position (CMP) sensor on 5 cylinder engines.

Diagnostic trouble code (DTC) is stored ECM-3000 or ECM-3010 is stored if the pulse width modulation signal from the camshaft position (CMP) sensor is constantly high (signal too high) or low (signal too low).

Diagnostic trouble code (DTC) ECM-3000 or ECM-3010 is stored if the pulse width modulation signal from the camshaft position (CMP) sensor is missing but returns sporadically (missing signal).

Diagnostic trouble code (DTC) ECM-3000 or ECM-3010 is stored if the pulse width modulation signal from the camshaft position (CMP) sensor is sporadically missing (faulty signal).

The fault is diagnosed by the control module when the engine is running.

Possible Source 

Signal too high: 

• Open-circuit in the signal cable
• Short-circuit to supply voltage in the signal cable
• Short-circuit to ground in the power cable
• Open-circuit in the ground lead
• Defective camshaft position (CMP) sensor.

Signal too low: 

• Short-circuit to ground in the signal cable
• Open-circuit in the power cable
• Loose connections.

Signal missing: 

• The camshaft position (CMP) sensor is in the wrong position
• Defective camshaft position (CMP) sensor
• Loose connections.

Faulty signal: 

• The camshaft position (CMP) sensor is in the wrong position
• Defective camshaft position (CMP) sensor
• Loose connections.

Fault symptom[s] 

• The engine is difficult to start.
