DTC P0607: Lost Communication with Electronic Throttle Control System (ETCS)
- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
- YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM (see PCM UPDATING AND SUBSTITUTION FOR TESTING ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see PCM REPLACEMENT ).
- NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the throttle body and the PCM.
