SYMPTOM
• The MIL comes on, and DTC P14A0 (Engine Abnormal Vibration) and/or P1DFD (Power System Indicator Lighting
Request From PCM) are set.
• Accord Plug-In only - DTC P0300 (Random Misfire Detected), P0301 (No. 1 Cylinder Misfire Detected), P0302 (No.
2 Cylinder Misfire Detected), P0303 (No. 3 Cylinder Misfire Detected), and/or P0304 (No. 4 Cylinder Misfire
Detected) may be set.
• Engine vibrates similar to conditions for misfire and/or loss of power.
POSSIBLE CAUSES
An inaccurate calibration setting in the software is causing engine torque fluctuations while driving at highway speeds.
This will cause the MIL to come on and the vehicle may enter fail-safe mode, which will limit the vehicles power output.
CORRECTIVE ACTION
Update the PGM-FI software.
