Was bedeutet der Fehlercode?
The engine control module (ECM) tries to adapt the throttle unit. If it finds that the throttle's movement is blocked, or if its opening spring is not working properly, the code is set. The fault can come from a sticking throttle, poor contacts, damaged wiring or a damaged throttle unit.
Mögliche Ursachen
- The throttle sticks or is blocked by oil film or dust
- Contact resistance or oxidation in the connectors between the throttle unit and the ECM
- Open circuit or short-circuit to ground or voltage in the wiring to the damper motor
- The wiring to the damper motor is short-circuited to itself
- Defective or damaged throttle unit
Was Sie tun können
- 1Read off the fault codes and first troubleshoot ECM-9150 and/or ECM-9160 if they are stored
- 2Check the connectors at the throttle unit and the engine control module for contact resistance and oxidation
- 3Check that the throttle is not blocked by any object or sticking, and clean it if necessary
- 4Use a multimeter to check that the damper motor wires have no open circuit and are not short-circuited to ground, voltage or each other
- 5If the fault code returns, the throttle unit is damaged, and a workshop should replace it and carry out the adaptation
Symptome, die Sie bemerken können2
- The Check engine lamp lights
- Performance is reduced
Was der Fehler beeinflussen kann1
- Depending on the fault, the ECM can disconnect the damper motor, and the throttle then tries to go back to rest
