i have cleared all my codes by disconnecting the battery for a long period of time, i still get a 121 TPS out of range code... i thought i was getting this code because i had unplugged it but it has come back, I have tested this according to the chilton manual...
1. insert 0.1 mm feeler gauge between stop lever and throttle stop screw, verify there is continuity between terminals IDL and E
-yes
2. replace feeler gauge w/ 0.7 mm and verify there is NO continuity
- there IS still continuity according to my meter
3. then open throttle wide and verify there is still no continuity
-there still IS continuity, about 2-3 k ohms
4. insert 0.1 mm feeler gauge between stop lever and throttle stop screw, verify there is NO continuity between terminals POW and E
-there still IS continuity...
5. replace feeler gauge w/ 0.7 mm and verify there is NO continuity
-still is continuity....
6. open throttle wide and verify there is continuity between POW and E
-yes
basically, no matter what terminals i am testing.... i am getting continuity all the time.... a smooth flow of numbers rising everytime i open the throttle, the wider the throttle, the higher the numbers, i have good voltage as i mentioned earlier in the post, does this mean my tps is bad? i heard there is a way to set the TPS by the fan method, by turning it until the fans kick on in diagnostic mode then turning it back a little til they shut off... no matter how far i turn the tps the fans do not kick on... are there any other ways i can test this to be sure this is the problem? they are over 100 dollars i can't really afford to just replace it
