Replacing a TPS - '00 SSEi
Replacing a TPS - '00 SSEi
OK the car took another crap on me today. Pulled codes, it says that the refurbished MAF I recently purchased needs replaced already. Ive heard reports that the rebuilts will NEVER work in a Bonnie SuperCharged
But I also have a code of the TPS being bad. Any hints, pics? Costs? I looked in the older threads and couldnt find much info on replacing them.
So any info would be appreciated, and on this stuff, talk to me like Im five..
Thanks in advance

Re: Replacing a TPS - '00 SSEi
The TPS is real easy to change on the 3.8L. It's on the side of the TB facing the front of the vehicle.
1) Disconnect electrical connector
2) Remove the two torx screws (they may be a tamper resistant torx screw, if they are you'll need a tamper resistant bit)
3) Pull sensor out of TB.
Reverse for re-install, torque the screws to 18 inch/POUNDS of torque.
My question is though, what exact code are you getting?
choices;
P0121 Throttle Position sensor performance
P0122 Throttle Position sensor low voltage in circuit
P0123 Throttle Position sensor high voltage in circuit
P1122 Throttle Position sensor Intermittent low voltage in circuit
P1123 Throttle Position sensor Intermittent high voltage in circuit

Re: Replacing a TPS - '00 SSEi
The arrow points to the throttle position sensor. It will have the tamper resistant torx screws. The only thing to be careful of is to be certain that you get the paddle on the proper side of the tang on the throttle body. If you don't you won't be able to move the throttle. Testing how everything moves before you put it on will help you there. If you have to fight to align the screws, it's likely on the wrong side.

Re: Replacing a TPS - '00 SSEi
any reason they come with tamper resistant screws instead of regular ones?

Re: Replacing a TPS - '00 SSEi
So thieves trying to steal parts on a common engine couldn't make off with expensive electronic sensor and control parts with ease. :D
Of course, all it takes is the theives to have the tamper resistant bits and we're right back to square one.
Also, so that the average Joe poking around his engine didn't start accidently removing stuff not meant to be removed by anyone other than a "Trained and qualified" technician.

Hmm, in all my years working on cars, I've never heard of a thief stealing your fuel lines or brake lines...sqela wrote:Yet the fuel and brake lines aren't as tamper proofCMNTMXR57 wrote:So thieves trying to steal parts on a common engine couldn't make off with expensive electronic sensor and control parts with ease. :D
