STEP 1. Connector check: C-115 accelerator
pedal position connector
Q: Is the check result normal?
YES :
Go to Step 2 .
NO :
Repair or replace the connector.
STEP 2. Perform resistance measurement at C-
115 accelerator pedal position sensor connector.
• Disconnect connector, and measure at harness
side.
• Resistance between terminal No. 2 and earth.
OK: Continuity (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 4 .
NO :
Go to Step 3 .
