texanredneck Posted May 5, 2009 Share Posted May 5, 2009 I replaced my tps sensor and im having issues adjusting it with an ohmeter and I went searching threads but no one really touched base on adjusting tps with and ohmeter. Could somone give me some tips on what signals the tps sends out on what prongs for idle cruise and wot? Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted May 6, 2009 Share Posted May 6, 2009 The center and rearmost terminals should have continuity only at dead closed throttle. You should lose continuity with only the slightest movement of the throttle but let it move a few thousandths before you lose continuity or you could end up with it coming off and on a billion times per second with engine vibration. On the non turbos, you have three terminals and you get idle on the rearmost two and you also get "full throttle" coming in at about 3/4 to 7/8 of full throttle body opening. On the non-turbos the ecu only uses the idle. There are two microswitches inside it so you won't getting a change in resistence but rather on or off depending on throttle position.

roger.svoboda Posted May 6, 2009 Share Posted May 6, 2009 use one ohm scale if you use megohms you can measure your skin resistance and wonder what is going on. Quote Link to comment Share on other sites More sharing options...
texanredneck Posted May 6, 2009 Author Share Posted May 6, 2009 Thanks yall, my book said the same thing it just said that i would reach infinity instead of continuity. So i was kinda confused. Quote Link to comment Share on other sites More sharing options...
