My TPS went out and the only way I can get it new is I have to buy the whole throttle body for $200.00 and I do not want to pay that just for the sensor. But on the photo I loaded is this the sensor I need?

Hello,

Unfortunately, that is correct. The TPS is sold and serviced as part of the throttle body assembly. I have included the Original Equipment Manufacturer[OEM] parts numbers for you in the diagrams down below. Please go through them and get back to us with how everything turns out.

Thanks,
Alex

Yes. That appears to be the throttle position sensor but unfortunately they are not servicable that way. You may be able to find a used one but if you take them apart they normally don't operate when going back together.

Let me know if you have questions. Thanks

Thanks for the answers. I think i'm going to try getting a used one off another Cadillac. But will the TPS need to get relearn to my car?

Hello again,

In the diagrams down below I have included the removal and installation instructions for your vehicle's throttle body as well as the relearn procedure for the throttle position sensor when your done. These instructions are from the vehicle manufacturer, so you can be sure they will work. Please get back to us with how everything turns out.

Thanks,
Alex

Thanks again, but I’m not changing the whole throttle body. I’m just going to pop the sensor out on the side of the throttle body and put it on mine. Will it be the same process to relearn it?

I am not positive it will work but worth a try. The relearn is exactly the same so let us know how it turn out. Thanks

Will that cause a reduced engine power with that being ripped?

Hello again,

I don't think that is a broken vacuum line. Am I looking at the bottom or the top of the timing chain cover there?

Thanks,
Alex

It was not a hose it was a clamp. But when I started the car it was a loud hissing sound. Will a broke vacuum hose cause a reduced engine power?

Yes. It can cause a low power, but it normally would also cause the engine to run rough.

Hello again,

Engine torque is what you want out of an engine. Torque is a measurement of engine power. It is the rotational force that the engine produces. Have you ever floored the accelerator pedal on a sports car and been pinned back in the seat? The force that pins you back in the seat is torque. I hope that this helps.

Thanks,
Alex

Hello,

Have you checked for vacuum leaks? I know you were concerned about a broken vacuum hose earlier. I never got an answer, was it on top of the engine or the bottom? Here is a link below to a guide explaining how to find vacuum leaks:

https://www.2carpros.com/articles/how-to-use-an-engine-vacuum-gauge

Please go through this guide and report back with what you find.

Thanks,
Alex
