Knock Sensor
#1
My 95SE w/ 51K on it needs a new knock sensor. I saw a previous post about it and wasn't quite sure what it exactly does. Can I drive it until I get it replaced? Is it an emissions type of sensor. I've already have 5, yes count 'em, 5 02 sensors put in. What gives with this? Getting very discouraged with the car.

Please read the Sticky ECU Diagnostic Trouble Codes. Read the post for DTC 0304. It tells the location of the Knock Sensor and provides instructions for a resistance test.

Maybe not. Diagnostic Trouble Code 0304 may have been set when you had a bad Oxygen Sensor, as a consequence of that bad sensor. I suggest you reset the Engine Control Module and drive for a week. Then do another DTC readout to see if DTC 0304 has been set. DTC 0304 is an exception to the rule in this respect: it will not turn on the Malfunction Indicator Lamp.

Are you aware of any other DTCs that won't set the MIL? I think I should update the sticky with this info.
