Omega General Help / Lambda sensor issues
« on: 31 December 2022, 12:07:42 »
Some months ago, I had issues with a warning light telling me that there was a fault in the O2 sensor circuit (Bank 2,Sensor1). I had a new Bosch sensor fitted and all seemed well – until last night when the light came on again. I completed my long journey to Oxford and back and the car ran perfectly, despite the light.
This morning, I ran the OBD reader again:
P0150-08 - O2 sensor circuit malfunction (Bank 2 Sensor 1). Status:Present
P0173-03 - Unknown Error. Status:NotDetected
P0150-07 - O2 Sensor Circuit Slow Response (Bank 2 Sensor 1). Status:NotDetected
P0173-09 - Fuel trim malfunction (Bank 2). Status:Present
I cleared the codes and restarted the car and the light is currently out.
Any thoughts?
