Hey Matt in Yreka here....,had the SES light on for about 2 weeks now but I am not sure what the fix is. I have a 2000 discovery - All of these codes (below) came on at the same time driving home from work in town Is there likely to be a single culprit causing these sensors to trip?
I have no idea where to begin looking - should I clean all these connectors? I did change out the front o2s last weekend - codes went away, but they came back. Purge valve canister and MAF parts on the way but I doubt all these sensors blinked out at the same time? Thoughts?
P0134 - O2 Sensor Circuit No Activity Detected Sensor 1 Bank 1
P0135 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
P0154 - O2 Sensor Circuit No Activity Detected Bank 2 Sensor 1
P0155 - O2 Sensor Heater Circuit Malfunction Bank 2 Sensor 1
P0102 = Mass Airflow Circuit - Low Input
P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted
P0448 = EVAP system vent control circuit shorted
P0340 = Camshaft position sensor circuit malfunction Open/short circuit to vehicle supply or earth.
