ACCELERATOR PEDAL POSITION SENSOR CHECK
1. Disconnect the accelerator pedal position sensor connector.
2. Measure the resistance between accelerator pedal position sensor connector terminal No.1 [accelerator pedal position sensor (main) earth] and terminal No.2 [accelerator pedal position sensor (main) power supply] and between terminal No.7 [accelerator pedal position sensor (sub) earth] and terminal No.8 [accelerator pedal position sensor (sub) power supply].
Standard value: 3.5 - 6.5 kOhms
3. Measure the resistance between accelerator pedal position sensor connector terminal No.2 [accelerator pedal position sensor (main) power supply] and terminal No.3 [accelerator pedal position sensor (main) output]; and between terminal No.8 [accelerator pedal position sensor (sub) power supply] and terminal No.6 [accelerator pedal position sensor (sub) output].
4. If the measured values are outside the standard value range, or if the resistance does not change smoothly, replace the accelerator pedal position sensor.
NOTE: After replacement, adjust the accelerator pedal position switch and accelerator pedal position sensor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
