could some one tell me what code 22 is i think its high tps. if it is has anyone else had this problem and how did u fix it.

Check Techinfo for a code list.

code 22: Throttle position sensor

would swaping in a new one fix that?

Not necessarily, but likely. It could also be the wiring to and from it. It is best to test it first to see if there really is a problem with it.

I would try adjusting it first!

Depends on the year. I know there'* no adjustment on the 93.

just a side question..were do u get the codes from..a code reader or does it show on the dash if u turn the key on and off many times...jeeps do that...

Here you go!
Yes there is a way to retrieve codes yourself, but, it only works on models from 1985 - 1993!
On 1994 and later models a scanner must be used to retrieve the codes. You can try this way to see if it will work just in case my manual is wrong about the year. Find the "Assembly Line Communication Link (ALCL)" it usually found under the dash near the steering column. Now locate terminals "A" & "B", the 2 uppermost right-hand terminals, "A" is the one the right. You must use a short wire to ground out these terminals. While the terminal is grounded with the ignition "ON" and the engine stopped, the system will enter diagnostic mode. The ECM will display "Code 12" by flashing the "Service Engine Soon" light indicating the system is working. Code 12 is simply one flash, followed by a brief pause, then two flashes in quick succession. This code will flash three times. If no codes are stored code 12 will continue to flash until the ground is removed from the terminal.
After flashing three times, the ECM will display any stored trouble codes. Each code will be flashed three times then code 12 will be flashed again indicating display is completed.
Note: If the trouble is intermittent the engine light will come for about ten seconds then go out. If the trouble is more serious then the engine light will stay on and the trouble codes stored in the ECM memory until voltage is interrupted to the ECM. To clear the codes, disconnect the battery for about ten minutes.

That'* all up in Techinfo, too....and there'* more codes. If you come up with a code you don't see, let us know, and we can look it up.

Nuthin like a little information overload, eh?

Tell him more Al!
