It did, I was reading the connecter as I plugged it in several times and watched the supply voltage go to 0 each time I plugged it in, also if my tcm is bad would it cause this? Maybe the tps voltage input is shorted out in the TCM? Bc I’m also thinking my tcm is bad... so maybe my tcm on the...
No I tried to read the signal with everything plugged up but I couldn’t get the supply voltage or the input voltage so I thought about it and unplugged the connection and boom, had voltage on the tcm side, plugged it back in and immediately lost voltage, so I plugged my new OEM mopar TPS in and...
My TPS sensor is ready 0 volts with key on, when you unplug it, I get the 5 volts back, soon as you plug it back in the voltage disappears again and when I work throttle I see no change, I also tried a new TPS and just plugged it in to see if I got the same results and I did, any ideas?
Would it run okay with a bad TPS? And also the vacuum line assembly on the motor looks to be in poor shape so I’m going to replace the front and rear vacuum line assemblies, it seems the engine revs great but at idle it surges for some reason so could that be a TPS issue possibly? I’m at work...
So I got a new UPDATE! I actually got in touch with the original owner who done the swap and he said that it shifter fine when he swapped it initially but it eventually stopped shifting, so he swapped the TCM out and it fixed it but it only lasted a short while and it was back to not shifting...
The exact wiring harness, motor, trans all got installed from the Cherokee into the wrangler, it has the dual output tps sensor, I will check to see if the TCM has a ground, when they swapped the motor they might have left off a ground maybe, I just will have to sit down and work my way through...
Hey Guys, I’m new to the jeep world but been around them and worked on a few and here recently picked up a 1990 Jeep Wrangler with a CHEROKEE XJ ENGINE AND AUTO TRANS SWAP. The trans won’t shift out of 1st gear when in Drive, but if I pull the fuse, it will shift out manually, everything I’ve...
