Which Brand of TPS sensor?

[KEVINS]

I picked up a Sorenson TPS sensor and it's now sitting in the trash can b/c my attempt to get more than 3.9volts out of it at WOT failed. I see that Kirbans has a Wells brand, is this a better quality and will it give me the voltage I need w/o too much modification to it or is there another brand that I can get locally so I don't have to pay shipping?

I bought one from Autozone and I won't do that again!!

Did you try and file out the slots a little ?

sorry, Can't really recommend one other than a delco

File the slots? That's a joke.. The bottom screw had to be on the outside of the TPS sensor slot by about .030 in order to get 4.5volts at WOT. By the time I got done modifying it just to work it didn't work at all only going to 1.0 V at WOT..

Did you make sure that your IAC was within the realm of 15-30? You TPS and IAC adjustments go hand in hand. If you adjust one of the then you need to make the other adjustment. And yes that is a pain in the ass, but the price of owning a turbo car.

Also forgot.... Did anyone of you get the latest of Kirban's news letters? In it, he talks about most of the electronics for these cars come from the same manufacture. Now I would agree with that. There is this thing called ISO 9000. It is to insure that that certain specs met the buyer/sellers specs. That is why there are BorgWarner, Wells, Standard, and a few others. Even the AC Delco comes from the same manufacture, just different assembly line.

That's what the agenda was tonight. This TPS sensor just required waaay too much rotation in order to get the voltage right. At max rotation by hand it only went to 4.8 volts and there is no way my throttle would even rotate that far.
I've put two on this car over the 18yrs I've owned it and they were pretty easy to slot and get working. This one was waaaaaaaay off.

Not to be insulting, especially after 18yrs..... But with Key on and engine off the TPS needs to be at .42v off throttle and WOT about 4.56. So 4.80 is crazy and high. Plus if you don't have you UAC adjusted to around 20, then you will NEVER get the TPS set right and your throttle response will be EXTREMELY crappy. I bet that your throttle has a hesitation as we speak. SO ADJUST YOUR IAC TO FACTORY SPECS (something a lot of people don't do and wonder why they are having issue) and I bet that you will be able to get your TPS set correctly....

No problem with the comment but you're reading too much into what I wrote. The car was running great and I never had a problem with idle or hesitation with the old TPS sensor because the TPS and IAC was set last year during the general tuneup.
I was making some high boost runs with my new turbo yesterday when the TPS sensor went dead during a test run so I'm simply trying to replace it with no luck. I know 4.8 is too high. I couldn't get 3.9 out of it given the travel of the throttle and in order for me to get 4.5 at WOT I had to rotate the sensor so far that the bottom screw was outside the sensor completely and there was no way I could tighten it down. Or if I could get 4.5V at WOT then the voltage was .92 at closed throttle.

I read several comments in the archives about crappy Sorenson sensors and that's the brand I bought tonight so I was hoping that there was a brand that others trusted.

No problem..... O'reilly sells Borg Warner

i thought no check engine light appeared unless 5vdc was exceeded. 4.5to >5.

oops <5 less than 5

Rotation isn't what gives you the best WOT value. To adjust for WOT, first you loosen both screws, and slide the tps all the way forward, and tighen down the screws just snug. Now, check your WOT value (at this point the tps is all the forward, and idle value may be off a bit). Now, to adjust the idle value you want to loosen both screws, BUT....leave one just snug enough to keep the tps from sliding backward, it will act as a sort of hinge because the other srcrew will be loose enough to allow you to "tap" the nose(connector end) of the tps either up or down to get the idle value right.

Remember: Fully forward for WOT, nose up or down for IDLE.

BTW, 4.8 isn't too high. I'm running 4.85 without problems.

Thnx! I'll give them a try.

Advance has them in stock at some of their stores,just have to call your local store to see.

Did you pay more than $33.59 for it at NAPA?,thats what the price is at Advance.

For which brand? That's where I bought the first one (Sorenson) that is now sitting in the trashcan.

Some of the sales people at parts stores don't know anything about looking up parts. I have gone into stores and asked about a part and one sales person would tell me they don't carry that part and can't get it. I would go ask another sales person in the same store just a few minutes later and that person would go in the back and come out with it in hand. I don't have much faith in them and don't accept the first sales persons answer,you never know how long they have been working there,maybe only a few days.

Now I always go to the online websites and look up my parts and have the part numbers and prices before i go to the stores.

I have used the Sorenson,Wells,Standard and a few other brands and they all worked well. Maybe you got one that was defective,it does happen from time to time with some parts especially electrical sensor parts.

NOS4GN had some Delco TPS's but I don't see them on their site anymore. I think they are now discontinued. They sell one from "Standard" for 37.95.

I just went through setting my TPS. I got my IAC count to about 20 - 25 idle at operating temp. My TPS is .42 at idle and 4.35 at WOT. Accoring to Eric's instructions with his chip, he recommends .40 to .46 closed, and 4.20 to 4.60 at WOT and not to exceed 4.80 at WOT.
