86. Check for continuity between ECM/PCM connector terminal E5 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM/PCM (E5) and the FTP sensor.
NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/ PCM, then recheck. If the symptom/
indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
