Hi!!

The Throttle Body is the part where the Air Filter Hose Connects into. The Throttle Position Sensor and the Idle Air Control selenoid are located.

2003 Chevy avalanche reduce engine power what does


have it scanned usually this is a problem with the throttle actuator

Gm code p2120


Code p2120 is accelerator pedal position sensor APP sensor 1 circuit apparently this is known as the reduced engine power syndrome and is quite common on the avalanche. There is no mechanical linkage from gas pedal to throttle body and it is quite common for the throttle position sensor located on throttle body to mess up and throw this code and also for one of the wires to the throttle position sensor to get hot become brittle and sometimes break. I would start there

Avalange with emissions code p1516


The throttle actuator control (TAC)/ throttle body type trouble codes, may be caused by a loose wiring crimp at the throttle body connector, or a broken throttle body circuit. have you noticed reduced power?

My 2003 avalanche keeps going into reduce engine mode the codes say its the TPS/pedal position sensor where are they located


this is most likely a throttle body issue. accelerator pedal has position sensors on it but these trucks had some issues with the electric throttle body and harness plugging into it

The reduce engine light comes on at 50 mph what could the problem be


DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!

The engine light comes on and the reduced power is activated ,there sensors were tripped all to do with the throttle . the auto shop ended up replacing the throttle body and the problem just happend again...


I'd bring it back to the shop that put in the throttle body and have them check to see if the replacement was defective or failed. If not, you may have a bad throttle position sensor [part of the gas pedal] I'm assuming it worked fine for a while after the repairs with no problems then suddenly started acting up again. I've replaced a bunch of throttle bodies but only one position sensor so far. There's always the chance that there's a bad wire somplace or some other more exotic problem but I'll bet you'll find it at either the sensor or throttle body. Good luck, hope this helps!

Truck suddenly stopped running like battery was dead. Got a jump nut only ran for 1-2 seconds then stopped again


I have a 2003 Chevy Avalanche 1500 Z71 4X4. What you describe happened to me (6) times last week. #1, I replaced the ignition switch, $32.00. The issue happened again last night and recorded the code P1514 (Throttle Body performance condition). #2, I cleaned the MAF (mass airflow sensor) and the throttle body. These parts require specific cleaners, which can be purchased at any parts store. Truck runs like new. Best regards, Mike Pyne

I just bought an 07' chevy avalanche, and a throttle body spacer. i do not deal with car instalations to often. where do i locate what to start to remove for this instalation?


You'll start with the air intake housing.Then you'll see the throttle body pointing straight at you.Its in the middle of the motor on the top closest to the top fan shroud.Next all you really have to do is un hook the two sensors wires on the right side of the throttle body and undo the throttle linkage on the left side.The hoses underneath can be left on.Pull it forward and let it hang down out of the way and then remove the studs that held it on.No just repeat steps backwards only installing the spacer and gaskets and throttle body and the new bolt.Careful not to over tighten.Good luck and hope to have help you.Anymore questions i will gladly help..
