2000 ML320 Oxygen Sensors
All,
I have been trying to figure this out for a while. My 2000 ML320 is displaying O2 errors for all 4 oxygen sensors. I have tried a few things but wanted to share if it is common all 4 sensors go bad at the same time.
Codes:
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0155 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
I am thinking to buy all 4 bosch 13782 sensors but wanted to check if there is anything else i should check before buying all 4. the Mechanic replaced Relay K28 with fuse F45 but not really sure if this makes any difference.
advise will be appreciated.
