Error on my O2 sensor
Hi guys,
Ok so about last year this time I removed my middle box (just behind the cats on the C350 2008 model.)
About a month ago my car went in for the last service under motorplan. Yesterday my engine light came on. Took it to Merc and they did a diagnostics with Xentry. cam back with the Fault code 0559 - The trimming resistor connection of Oxygen sensor 1 (cylinder bank 1) has an electrical fault or open circuit.
Is this my sensor or what? I'm looking to trade in the car and I need this light to stay off till then lol. I don't have a ODBII and not sure if there's another way to reset this for now without taking it into Merc?
I did do some reading and found the normal ODBII codes is:
P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1)
P0132 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)
P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
I'm assuming I have the error P0130 then.
