Default Best Throttle Position Sensor to Purchase?

Hello From Texas,

I have heard and read many great things about your club and fellow associates. You run a very nice crew and great Forum. Great job. Very simple yet elegant operation!
My question is i am getting ready to purchase a TPS sensor and My buddy at autozone says $30.00 for a wells unit. My buddy at the dealers says $100.00! And last but not least my Buddy at advance auto says "borg_warner all the way"" for $72.00!
please any advice or info will much appriciated and many thanks in advance.

Kindest Regards,
Big Poppa.

Frankly, I think that they're all right. I've used everything from the Wells, to OEM and haven't found much of a difference. There may be some as far as longevity, but I haven't run into that.

I agree. On a TPS, go for the Wells. But when it comes to O2 sensors and spark plugs, either AC Delco or NGK only.

He might want to be careful, because I thought some of those aftermarket TPS were adjustable, i.e. screw slots instead of screw holes. Might need a multimeter to check for proper alignment if it'* the adjustable type.

That could be. I haven't run into one that was adjustable that wasn't originally, still a good warning just in case.

I would say Wells is also good. Thats what I ended up getting from AutoZone for $30 after the GP Sorensen one from Advance failed twice! Make sure not to get the $30 one from Advance, definitely get the Wells.

Thank you fellas,

I think I will try a wells unit on a lets see basis! I've read that these are will work over a broad range of cars and model yrs. If i have any funny problems then I will try a higher priced sensor. Now when i adjust that TPS with the multimeter I should be on DC volts? Or ohms setting. If I remember my manuel I should look for .45-.70 closed throttle to 4.45 WOT! Is that pretty much it for a regular TPS switch out?? Anything else I should be on the look out for?? Once again thnks to all.

willwren,

You are 1000% right when you mentioned to use only Acdelco O2 sensors! I learned a very painful lesson trying to get by with a "El Cheapo" Bosch O2 sensor! Man, what a mess that was..Never again!! Thanks, fellas. Be Safe.

woah there...45-70 is a big range..i'm trying to remember what mine is at...I'm PRETTY darn sure its supposed to be in the 50s range. But your SES light WILL come on if its out of adj, so thats a pretty good way to tell!!!

I knew I was not sure about the closed throttle range. And I can't find my manuel for the life of me. 45 to .50 sounds about right to you then?? I need that book!!! Please help I am ready to do this tonight! You are very right..SES light will defininetly let you know things are out of whack!!
