oxygen sensor
my engine light came on when i was driving down the highway yesterday. I did a diagnostic check when i came back and got a code 21 (oxygen sensor signal).
It could be the oxygen sensor itself or the wiring, ( Checked all the connections..no loose wires or dry rotting here)I dont know yet. any way of telling? any way of cleaning the sensor? Because a new one if really expensive. |
