Hey guys,

I am finishing a b16 sir2 obd1 swap into a 1997 lx 4 door civic that previously had a d16y7 and is obd2a.

I had to swap out the tps from the b16 since it was smashed up and noew I am throwing a code 7 and my idle is fluctuating.

I keep finding wire colors and writeups of how to check for the tps voltage on obd1 hondas but nothing about obd2a wire colors for the tps and which one does what.

I'm not having any luck getting a voltage reading when the key is set to on and when I put a paper clip on the back side of any of the 3 wires.

Please help

 

It's the middle wire, and try cutting and pulling back some of the insulation on the wire to get a good reading.

 

I think that one is red and blue will give that a try when I have a chance now I need a new throttle body gasket because the bolts for the tps broke in the throttle body when I tried loosening them and I had to remove the tb and drill them out...

 

Just probe the pin on the ecu it's alot easier to get at. Should be d1 ( most top left wire on the third block of ur ecu). Make sure the key is on when u test it too. Should be right around .50 volts.

I find it easier to do it at the throttle body so you can check voltage at full throttle and adjust it without going back in the car to see since the voltage will move as you tighten down the screws.
