I'm looking at picking up a 2006 SS/SC that's been around the block a time or two.

It's currently throwing 3 codes, P0121, P0128, and P2229

I was planning on replacing the Coolant Sensor, Throttle Position Sensor, and Barometric Pressure Sensor.

The coolant sensor code is typically just a sensor failure on every car I've experienced a failure on. I ain't even worried.

The TPS sensor code: Is the TPS integrated into the Throttle Body? I can't find an independent sensor...


The BPS Code: Is the BPS called the MAP at the parts stores? I don't have a manual and I normally don't mess with these cars. I would expect purely from the name that the BPS is the MAP.

Thanks in advance folks

 

Baro sensor is separate from the MAP. Baro is a 3 wire sensor and MAP is a 4 wire because it also has iat2 in it. It is sometimes referred to as a TMAP (temperature and map).

TPS is part of the throttle body. Must replace the whole unit.

 

That's good info. I couldn't find it easily using the forum search function. I hate that the TPS is integrated. That's a PITA.

 

Yeah the tps sucks to change or well the whole TB. Im my tc I removed the manifold to remove it took me like 40 mins to install

 

He has an LSJ. It's fairly easier.

Take intake off.
Unplug throttle body connecter underneath
disconect evap hose on front of throttle body
remove the 4 10mm bolts that hold the throttlebody on
then reverse process

 

Lol good for him

 

I'm just looking for a cheap and slow DD. =D

 

It's pretty easy from below...

 

Well it is if you have a good jacks or a lift lol but now i can do it in no time
