There is a Tecnical Service Bulletin (TSB) that specifically addresses codes P0120, P0220, and P1516.

It says that the TAC Module can set these codes erroneously under certain conditions. It is very likely that if your vehicle is diagnosed according to the provisions of this bulletin, the problem can be corrected without having to purchase or replace any parts.

It is Technical Service Bulletin number 03-06-04-032
Issued June 16, 2003

Error codes 2101 and 1516 on my 2004 chevy trailblazer


DTC P2101-
The commanded throttle position (TP), based on accelerator pedal position (APP) and possibly other limiting factors, is compared to the actual TP. The 2 values should be within a calibrated range of each other. Both the powertrain control module (PCM) and the throttle actuator control (TAC) module redundantly monitor the commanded and actual TP. This DTC sets if the PCM detects an out-of-range condition between commanded and actual throttle position.
DTC P1516
The predicted throttle position (TP) is compared to the actual throttle position. The two values should be within a calibrated range of each other. Both the powertrain control module (PCM) and the throttle actuator control (TAC) module redundantly monitor the predicted and actual throttle position. This DTC sets if the PCM detects an out of range condition between the predicted and actual throttle position.

Do you know what electronic throttle control is ?

2004 GMC Envoy SLT 4.2L the engine will crank but want start why?


P1516 = Throttle Actuator Position Performance
P2101 = Throttle Actuator "A" Control Motor Circuit Range/Performance

Both of these codes indicate a problem with your throttle position actuator system. I'm not sure how GMC/Chevy treat this, it's possible that if the PCM/ECM will not allow the engine to start if the throttle actuator is not working properly (it may cause the engine to accelerate rapidly when running). You could try replacing the throttle actuator, but that may not solve the problem if it's a wiring issue. Best to have it checked out by a qualified mechanic.

I push the gas pedal on my 2004 CTS and it does not go what is the problem


Your caddy has Electronic throttle control ,drive by wire ! Do you know what this is ? You gas pedal ,if you look at it has wires connected to it .These wires hook up to the engine computer ,the engine computer has more wires that hook up to a dc electric motor under the hood on the throttle body which open an close the throttle plate ,which makes the vehicle go faster or slow down !

Are there any messages on your dash REDUCED POWER ? Check engine light lit ?

DTC P1516 Throttle Actuator Control(TAC) Module Throttle Actuator Position Performance

It only can be repaired at dealer, BUT you can try this first, by disconnecting the connectors at throttle body area and clean the connector with connector cleaner spray, and reconnect it. If it still doesn't solve the issue at all, take it to the dealer.

P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.
