Help TPS senser after replace it

Hi
This my first post ....
I have problem on my jeep wrangler TJ 1999. The problem comes after the car vibration because I swap my 33'' tire with small tires. Now I change it to 33'' but I got one code with engine light (p0122) I read that the TPS need to change. I already change TPS but still it show p0122 comes up.

The problem is still on the car I have replaced the throttle body with my friend to check but it still have the same problem.

My throttle seems to have a dead spot in it when accelerating a specific position of the pedal of the rpm around 2k.

Is the check engine light on. You need to clear the codes because it stays in memory once the code sets.

Check your connections if you replaced your tps. I replaced mine 2 weeks ago when I popped that code and I was good to go. No more cutting out while accelerating ect.

Was it an aftermarket or OEM from the dealer. A lot of auto store electrical parts are from china and do not work. Mine went a few years ago and I will only use electrical parts from the dealer. You get what you pay for. You see a lot of threads about the poor quality from auto parts stores.

you may have gotten a bad (new) TPS. It seems to be very common. Look at the connector and make sure that the terminals inside are not corroded. Also check the two connectors in the center of the engine bay for corrosion (the ones above the enging closest to the cowl) and lastly the three connectors that go the PCM. Clean them all with contact cleaner and apply di electric grease then put them back together. I would start with that.

Did you clean them up real good? Did the problem persist?

^^^ This.

1. Disconnect Positive battery lead terminal and touch it to ground for 30 seconds (Once the lead is disconnected, I attach a jumper cable and touch it the Negative on the battery)
2. Reconnect the Positive battery cable
3. Turn ignition switch on (DO NOT crank or start the engine).
4. Turn headlights on
5. Turn headlights off
6. Turn ignition key off.

This will reset the engines computer and clear any stored codes.
Jeep may run rough for a minute or two until it relearns itself but will soon smooth itself out.

He does not need to "flash" the PCM which is what that sequence is for. He simply needs to disconnect the negative terminal for a few seconds to reset that code.

It's easier to clear codes with a code reader. They are not very expensive and handy to have your own. Everyone in the family borrows mine. Then you do not have to reset the clock and radio presets.

I don't see why you need to "clear" the codes. I replaced mine after my light came on and it has yet to come back on well over 1000 miles

That was also my problem. I was just curious as why "exactly" you need to clear the history. When I replaced mine my light never came back on. So, so what it's in the history but it's not tripping anymore.

There really is no need to clear the codes. If the problem is fixed, the light will go off pretty much right away. Yes you can do the converse, and clear and hope it wil not come back on. If the problem still exists, it will pop back on pretty quickly.

Maybe it's not the TPS. Maybe the IAC is corroded.
