The PCM provides a 5volt reference voltage to the Acceleration Position Sensor1(APS1). The PCM monitors reference voltage deviation from the power supply circuit of the APS1.
PCM sets DTC P0698 if the PCM detects reference voltage is lower than threshold value.
Item | Detecting Condition | Possible Cause | |
Case 1 | DTC Strategy |
•
Short to ground | 1. Short to ground in power circuit 2. Poor connection or damaged harness 3. Faulty APS1 |
Enable Conditions |
•
IG "ON" | ||

Limp-Home |
•
Forced limited power mode : The PCM limits opening angle of the throttle valve to max. 50% and engine torque to a certain pre-determined value.
•
After idle recognition, the PCM uses APS2 signal to calculate the current opening angle of the throttle valve.. | ||
