TPS Adjustment (automatic)

[Jtslick89]

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?

TPS is likely bad.

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.

You have done my Tips? At least 1 through 5?

So @cruiser54 was spot on (what a surprise 😆).

 

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
