Hey guys,
Got a new problem with my little micra, the throttle position sensor stopped working and was returning no value at all on the diagnostic software. Idle was bouncing around all over the place. Got a couple of spare throttle position sensors that were in a job lot of things I bought from a friend, anyway I've fitted one to the car and the idle has returned to its normal 640 rpm but I now have a cylinder 4 misfire that happens at idle. It doesn't throw the dreaded check engine light on but appears as a pending code on my diagnostic software. I did notice however that the ignition timing advance at idle will not sit at 15 degrees. It jumps around between 11 and 18 degrees.
I can get it to sit at 15 degrees by loosening the sensor, adjusting its position and tightening the little screws. Doing this stops the misfire happening. If I turn off the engine then restart it the ignition timing returns to its state of jumping around and the misfire coming back.
My question is there a specific way to set/calibrate the throttle position sensor?
Thanks
