Inspect Accelerator Pedal Position Sensor

WARNING: This page is about a different car, the 2004 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the sensor connector.

Using an ohmmeter, measure the resistance between the each terminals.

Resistance:

TERMINAL RESISTANCE SPECIFICATION

Terminals	Resistance
VCP1 - EP1	2.25 to 4.75 kΩ at 20°C (68°F)
VCP2 - EP2	2.25 to 4.75 kΩ at 20°C (68°F)

If the resistance is not as specified, replace the accelerator pedal assembly.

Reconnect the sensor connector.
NOTE:
- Be careful not to give a shock to the accelerator pedal assembly.
- Be careful not to disassemble the accelerator pedal assembly.
