| DETECTION CONDITION |
- If any of the following conditions continue for a specified period of time or more the PCM detects a malfunction in the throttle valve actuator.
- The voltage of the motor power supply is 4 V or less
while the motor relay is on.
- There is a system error in the electrical throttle control system of the PCM.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Stops the idle air control.
- Stops the drive-by-wire control and sets to a throttle valve opening angle necessary for the minimum driveability.
- Limits the vehicle speed to less than 20 km/h {12 mph}
.
