Title: Throttle Postion Sensor trouble
Post by: IrishBilly on March 18, 2008, 08:17:20 PM

I receintly found out i had a bad tps sensor on my 1995 sidekick 16 valve 4 dr. I sucked it up and payed the $187.00 dollars  and installed a new one myself as per instructions in my chiltons manual. Upon installtion i reset the codes my remove both battery cables for several minutes and removing ecu fuse . I still have the same problem i still have next to nothing when it comes to throttle response i have replaced spark plugs ,wires, cap,roter, fuel and air filters and had injectors cleaned. What should i do next

Check the wiring, a friend had this problem and it was a broken wire from the TPS to the ECU. I bypassed the wire and it runs great.

have you checked to see if you have enough fuel pressure at the injector's.  Mine is a 8v and had that problem kinda.  Come to find out the fuel pump was bad.

why do u believe the tps is the fault? Have u had the codes read? Sometimes auto parts stores will loan scanners. If u get real lucky ull get someone toview the tps voltage and diagnois the fault.

You can read the codes yourself on a 95.

21 is TPS signal high
44 is Idle switch circuit open

Is it properly adjusted? if it is then you need to check the ground wire. The ground wire should be grey/yellow and goes to A24 on the ECU.

Code 22 = TPS signal voltage low. The opposite of what you had before, did you adjust the TPS again? Otherwise it sounds like you have bad connections.
