Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-92D0

Condition




The diagnostic trouble code (DTC) is stored if the ignition has been left on for 30 seconds and the engine control module (ECM) has been unable to adapt the electronic throttle unit. This is because the programmed parameter for the stop position in the throttle position (TP) sensor has been exceeded. Adaptation is usually carried out to ensure that the throttle unit parameters are within the programmed values that are stored in the engine control module (ECM). If other diagnostic trouble codes (DTCs) are stored, these must be remedied first. These may have caused the adaptation to fail.

Substitute value
The engine control module (ECM) uses parameters from previous successful adaptations.

Possible source
- The throttle is sticking or is blocked (e.g. oil film, dust)
- Contact resistance or oxidation in the terminals between the engine control module (ECM) and the electronic throttle unit
- Damaged throttle unit.

Fault symptom[s]
- None.
