Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Trouble Code (DTC) Information ECM-P060662
Condition
The Engine control module (ECM) continuously monitors a number of internal signals through calculations and compares them. The aim is to ensure reliability during operation.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Internal checks give unacceptable results.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.
Substitute Value
- Various internal signals in the engine control module (ECM) are replaced with default values.
Possible Source
- Sequential fault related to throttle. Therefore fault-trace for another diagnostic trouble code (DTC).
- Poorly charged battery or corroded connecting wiring.
- Damaged software in the engine control module (ECM).
- Damaged engine control module (ECM).
