Hello everyone,
I'm bringing this tread up since it seems I have the same problem.
Last week my "Check Engine" light went on for a day, and went back off. I checked with a scanner and it gave a Knock Sensor error code.
I disconnected the sensor, sprayed it with a contact cleaner and connected it back (it was clean but since it was already out I figured why not).
Today, the light went back on.
Any ideas anyone?
I also saw at the Kia Tech Info that I could check the sensor with a voltmeter, and I need to measure the voltage between ground and Terminal 3 (yel/grn).
Can someone pleas tell me where is this Terminal 3 inspection point?
The car is 2001, SWB sportage, with a little over 100,000 miles.
Thanks,
Lior
