Could other sensors cause an error 24? I am awaiting a new o2 sensor...just don't want to replace every sensor to only have the same problem.

Thank you for your help

Map maybe. You can check the tps with a meter.

Maybe try wiggling the wires going into the TPS, see what happens. How is the connector there, is it solid?

Good point, the plastic clip which locks it in place is broken off

Well so far so good, I just install the O2 sensor. Jeep Seems to be running good but idling a little higher than normal around 950. Check engine light did come on right after I started it, I turn it off then restarted it and so far it has stayed off...we'll see what happens. Thanks again for all your valuable input

950 is about right when its cold, see what it does when it gets good and warm. The light came on but there is no codes?

How did you figure the o2 sensor was bad? I usual ask because the symptom is a difference between the way it runs hot and cold. Did you disconnect the battery after you replaced the sensor?

The light did come back on but this time I have no starting issues after it is hot. Getting error 24 again...I ordered a new tps. Hope this fixes it, seems to run ok

Have you checked for vacuum leaks as well. When I did my engine swap (Que and Pete got me through it) I broke a vac line and was having trouble finding a replacment as it was the molded line. Soooo I capped it off on the throttle body until I could find a new one. Capping it off caused me to keep getting the code for the TPS. Once I made a vac line to fit it and reset the ECM no more code and she has run flawlessly since.

1995 YJ. 2 inch BDS Spring lift. 1 inch shackle lift. 1.25 inch JKS Body Lift 33x12.5x15's. Engo 10,000 pound winch.

Thank you Siva...so I went and inspected all of my vacuum Lines and I did not see any physical cracks . I disconnected the vacuum line that runs off the manifold to the firewall and plugged it. Restarted the engine the check engine light did not even come on this time, what is the purpose of this vacuum line? And is it needed...seems like all my heater controls work properly Name:  image-557589682.jpg

Size:  425.8 KB Also the white cap you see is a plug… I installed a positive lock a while back Is it just a coincidence the light went off after I blocked this vacuum line… Would this cause the check engine light not to show error 24 I appreciate everybody's help, thank you so much

Scratch my last posting...

Went back out to check the engine again, the check engine light stayed on so looks like I'm back to step one with the Error code 24. When I first started it I was getting lots of fluctuation in the engine idle like it was surging then dying almost then surging and dying...eventually it leveled out but the check engine light is still on.

I have a new TPS sensor on order should be here tomorrow.

DTR did you ever check the resistance or voltage on the tps. There are many youtube videos on doing it. This thread has how to test it:

No do not have one, and don't know how to use one.
