-- If necessary, repair the faulty wiring connection and replace any open fuses.
-- Go to Final procedures
If the specified value was obtained:
-- If no faults were found. Replace the Fuel Temperature Sensor -G81-. Refer to appropriate service information.
-- Go to Final procedures
Final procedures
After repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
