STEP 3. Check the continuity at accelerator pedal position 
sensor harness side connector C-24.
(1) Disconnect the connector C-24 and measure at the harness 

side.

(2) Measure the continuity between terminal No. 2 and ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 6.
NO :  Go to Step 4.
