Question about Cars & Trucks
My "check engine" light keeps coming on and off. It has thrown a knock sensor code each time. I completely replaced the knock sensor and it is still coming on and off. It gives four reasons: 1) Sensor has gone bad. 2) Wiring to sensor needs to be checked. 3) Rattle or Knock in motor. 4) Low fuel pressure. What is the problem here? I drive the card EXTREMELY HARD at times and am preoccupied with any potential damage that may occur. These cars are MADE to be driven at a more aggressive level. Why make them perform if they can't take it? I keep on top of all mainenance and by no means neglect it in any way. Any help is appreciated.

CA you can take the car to a referree and get a one time waiver if you have spent a minimum of $450 on repairs not including smog fees. Gives you two years to get it fixed.

The knock sensor is a major pain in the a..s to change I would suggest taking it to a reputable shop for a second opinion to see if they realy performed the work. Also with OBD11 (2) diagnostics if you have multiple misfires its not the wires its something else, also if you got a code for a misfire it would be specific as to which cylinder is misfiring. My best guess would be to get your coil checked.

Your sensor went off because it overknocked.
Try using a different type of fuel with a higher octane.
Erase the code and use the better gas. if it comes back then we will worry about replacing it.
