- Standard voltage:
- Accel Position No. 1:
Accelerator Pedal Specified Condition Released 0.5 to 1.1 V Depressed 2.6 to 4.5 V - Accel Position No. 2:
Accelerator Pedal Specified Condition Released 1.2 to 2.0 V Depressed 3.4 to 5.0 V
If the result is not as specified, check the accelerator pedal, wire harness and ECM.
Inspect the accelerator position sensor resistance.
Using an ohmmeter, measure the resistance between each terminal.
- Resistance:
- RHD:
