Diagnostic Trouble Code (DTC) Information ECM-160A
Condition
The engine control module (ECM) checks the difference between the requested throttle position and the actual position.
The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that the difference was sufficiently great to affect emissions during warming up of the catalytic converter.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running and the three-way catalytic converter is being heated up.
Substitute Value
- None.
Possible Source
- Other diagnostic trouble codes (DTCs) stored in the engine control module (ECM)
- Contact resistance or oxidation in the terminals between the throttle unit and the engine control module (ECM)
- Damaged throttle unit.
