Diagnostic Trouble Code (DTC) Information ECM-5000

Condition

The engine control module (ECM) detects the flywheel position for TDC using the signal from the engine speed (RPM) sensor. The diagnostic trouble code (DTC) is stored if the position for TDC is missing sporadically. 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
• Variable valve timing control is blocked.

Possible Source 

• Signal interference
• Contact resistance and oxidation
• Intermittent fault causes in the engine speed (RPM) sensor wiring.

Fault symptom[s] 

• The engine is difficult to start
• Poor performance.
