Honda Trouble Codes and Known Issues

Honda builds very durable gasoline engines with VTEC and i-VTEC variable valve timing. The most searched codes involve the EVAP system, the oxygen sensors and, on some early-2000s models, the automatic transmissions.

Most searched models: Civic, CR-V, Accord, Fit / Jazz, City, HR-V, Pilot and Odyssey.

Common problems on Honda vehicles

• Automatic transmissions on early-2000s Accord and Odyssey V6 models.
• Variable Cylinder Management (VCM) on V6 engines, linked to misfires and oil consumption.
• Oxygen and air-fuel ratio sensor heaters.
• VTC actuator rattle on cold starts on K-series engines.

Tips for diagnosing a Honda

• Use Honda ATF DW-1 transmission fluid: universal fluids cause harsh shifts.
• Many Hondas also show manufacturer codes (P1xxx) for the EVAP system; read them with a scan tool that shows their description.
