When I searched on here for the code all the post say TPS. Am I missing something? P1120 Throttle Position Sensor out of range. Disconnect sensor's terminals, measure resistance between, center terminal and other outer terminals. Per Haynes, resistance should be between 400 to 6000 ohms. Edit. This thread might help you decide what to do. http://www.contour.org/ubbthreads/showflat.php?Cat=&Board=trouble&Number=943656&Forum=trouble&Words=TPS&Match=Entire%20Phrase&Searchpage=1&Limit=25&Old=allposts&Main=943565&Search=true#Post943656 Last edited by Tony2005; 08/28/05 11:49 PM.

Maybe even the problem I talked about in my other thread. I put a new TPS on about 8 months ago or so and didn't drive it much. I'll pull it off and reinstall it just incase. Thanks again Tony! 2004 Evolution VIII cams-exhaust-tune 315whp 12.7@109
