Does anyone know the part number for the TPS? I've been loosing engine power and getting the P2135 code. Can I buy just the sensor or do I need a whole new throttle body?

2011 HHR 2.4l

 

Whole new throttle body and or new pedal position sensor.

Read this: P2135 Chevrolet Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation OBDII Engine Light Trouble Code | Engine-Codes.com

 

Thanks. I think it might be the wiring harness too. Wires are a little loose.

 

Take a look at this thread also.

Okay, so looking at the GM bulletin they give a part number of 19259452. The listings I've found show for 6.2l Cadillacs and bigger chevrolets/GMC's. I'm thinking it should be the exact same thing. A part number is a part number. For $35 it's not like I'm making a huge invstment so it's woth a shot. http://www.ebay.com/itm/161413324937?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

Has anyone here tried this? http://www.ebay.com/itm/161413324937?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT I read the part number in a GM bulletin for the P2135 code. It looks the same but listings are for bigger GM motors.

 

I'm pretty sure the TPS(throttle position sensor) is integral to the throttle body on all HHRs.
The PPS(pedal position sensor) for the accelerator pedal, now that's another part of the system.
What you show is a Throttle Body Sensor. Not sure if the HHR actually has one by that name.

Yeah. I'm even confused myself now.

Fwiw. I think donbrew already said you need the whole TB in post #2.

 

It's not my money. Throw all you want at it, you might get lucky.

 

Does the GM bulletin you cite specifically state your engine/model/year/size?

Oddly enough the eBay compatibility guide says no.

 

Well I bought the part and its slightly different. It the same thing, the black box on the side of the throttle body but the shape is different. Someone has to know the part number or where I can find it on the sensor myself. I need my daily driver back up and running and would rather not spend $90+ on a new throttle body.
