knock sensor q
Posted: October 27th, 2008, 3:07 pm
well i'm still trying to get rid of this slight stumbling/misfire problem, and i'm pretty sure its the knock sensor, since i'm pulling code 05 off the ecu.
basically what happened is, a long time ago my car wouldn't start. i looked over the harness and found a broken wire, which was the knock sensor ground. on the harness side, i just grounded this wire, and everything ran fine. this is probably the point at which the stumbling became an issue.
this weekend, i took that grounded wire off the grounding point, spliced open the insulation around the main wire of the knock sensor, which has the ground wire wrapped around it, and put those two together. essentially it should be exactly like it was intended to be. however, this way the car doesn't start.
so i have two questions. first of all, what's up with this? why isn't it working like this? secondly, i'm trying to figure out if i even need to have the wiring attached to ground wire of the sensor, or if just any grounding point is fine. like i said, i'm getting the knock sensor code, so i'm curious if the circuit is not complete bc of the wiring, or if something is actually wrong with the sensor.
i'd aprpeciate your input
