- We scanned for codes and found P0446 evap vent control problem. We then checked the purge valve and vent valve and found both are operating according to spec. We also induced smoke into the evap system and found no leaks. We pressurized the fuel tank and monitored live data and found the pressure sensor showed no change. Recommend fuel tank pressure sensor.
- We replaced the fuel tank pressure sensor and then test drove to run all the monitors. All the monitors have now run and the vehicle is ready to smog.
