My TPS is out, it went south when I had a power coolant flush done at Chevy today. It idles at about 1750 or so, goes up to 3k RPM and doesn't shift, they used the Tech Two and it said that the throttle Sensor was out, would this sensor cause all this?????


Thanks alot!

I would just get a new GM tps sensor and see if it fixes your problems.

i did get the new sensor, I couldn't drive the car home though, so it will sit inside my local chevy dealer until friday. I believe that the sensor is what is causing all this.

TPS will absolutely cause all of that, I pinched my TPS wires installing the alternator bracket on my intake manifold and it did the exact same thing.

The sensor could be out of adjustment. I tested mine with a volt meter, I believe they are supposed to read .67 volts, mine was reading .56. I adjusted it and the car finally started to idle right. Before it would try and die everytime I would come to a stop.

I do not remember which wire it is you check, but to adjust it, you take the sensor off the car. Then you have to make the holes in the sensor an obround shape. You put it back on the car and make the screws hand tight, then with the voltmeter on the wire, you rotate the sensor until it reads as close to .67 volts as you can get, then tighten it down. Very simple, took like 10 minutes.

A stock TPS on a stock TB has no adjustment (slotting the mounting holes is usually done to make it adjustable when using an aftermarket TB). If it is out of whack, it really should just be replaced.

TPS voltages and values can easily be tracked with a scanner. The engine does not even have to be running (just the key ON).

I was looking for a write-up on your site about this, I thought there was one, but I could not find it.

The TPS sensor is extremely impotrant to auto cars. It will deffinately screw up the shifting of the trans cause it speaks directly to the computer controling the trans. Manual cars are not afected as badly, but it will still need to be replaced. I would suggest just replacing the sensor, rather than wasting your time carving out the plastic and trying to adjust it. I dont think it would help in your case anyways.

There isn't one, but Golen has a guide.

So I have the same problem also. I can't get my idle back down since the new motor w/ heads cam. Stocker tb. its idling 1100 or so. LOL I tried the slotting method, didn't know it was only for aftermarket tb's.
