Jtslick89 Posted November 12, 2021 Share Posted November 12, 2021 Hey guys, Using @cruiser54 guide for TPS adjustment for automatic. On the 3 pin connector I can get a base voltage of around 4.86, but I cannot get an OUTPUT voltage? (Is that possible) 4 pin connector I can get BOTH base and OUTPUT voltage. Need help on the ENGINE side of the TPS. Any thoughts? Link to comment Share on other sites More sharing options...
cruiser54 Posted November 14, 2021 Share Posted November 14, 2021 TPS is likely bad. Link to comment Share on other sites More sharing options...
Jtslick89 Posted November 14, 2021 Author Share Posted November 14, 2021 thanks @cruiser54, i tested my '90 MJ and '87 XJ on both the engine and trans side (both are automatics) and the only reading i cannot get is the engine side of the XJ output.

I replaced the TPS with an OEM one today and lo and behold, the output voltage on the flat connector went to 0.82 V (17% of 4.85 my base voltage) Long story short, bad TPS Link to comment Share on other sites More sharing options...
