I had a knock sensor going bad and can't afford to buy a new one. Well I decided to reroute my wires away from the exhaust. Hooked it back into the knock sensor. Hooked my battery back up and then fired up the car. Idled at 1500-2000RPM but I know the reason for that is the Idle Relearn. My Check engine light came back on and now its reading a totally different code. Its 2Pause 2 Flash which is TPS Circuit. It's a new TPS sensor, well fairly new. But when I drive it the light goes out. Whats the downfall of driving my anyways? Thanks in advance!!!!
