AdamB Posted June 21, 2013 Share Posted June 21, 2013 41 is the TPS and 52 is Knock sensor. Check the wiring on the knock sensor, and check to make sure that it is earthed properly, I believe they are earthed through the shroud and onto the block.Check the wiring on the TPS, or swap it for another item. When you do either reset the battery and try again to see if you still get the EML come on. Quote Link to post Share on other sites
mikey4410 Posted June 30, 2013 Author Share Posted June 30, 2013 this is fixed,issue with throttle position sensor was it wasnt set right on the "timing" style marks,adjusted it and guessed and put it bang in the middle of adjustments and fixed it. the knock sensor issue was down to damaged wiring, thanks so much for all replys guys,top stuff and appreciate it Quote Link to post Share on other sites
