Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




Engine control module (ECM) checks the signals from the electronic throttle unit's two position sensors.
If engine control module (ECM) detects unreasonably high signal from any of the sensors, the diagnostic trouble code is generated.
The diagnostic trouble code can be diagnosed when the ignition is on.

Substitute value
- In case a defective signal is detected, the other signal is used.
- Cruise control turned off when malfunction is active.

Possible source
- Contact resistance or oxidation in the terminals
- Signal cables short-circuited to voltage.
- Voltage feed short-circuited to battery voltage.
- Open circuit in ground cable.
- Ground cable short-circuited to voltage.
- Damaged electronic throttle unit.
