It had worked for a month before i started getting issues, it started off as random times under acceleration or deceleration or even when cruise control was on, someone had already replaced the connector end to the throttle body so I then replaced the original throttle body itself, this did not work either. Given the numbers just mentioned, it would be best if most of the time the engine output were in the range of 40 to 50 hp. Then, the scan tool will be used to monitor the data stream and check the throttle and gas position sensor values as they are operated. Obviously not all the reduced engine power stuff is caused by the same thing. Here the intake valve duration and lift are significantly reduced to control airflow into the engine, allowing it to operate at higher intake manifold pressures with the potential to fully unthrottle the engine under all operating conditions. Getting greater efficiency is accomplished in several ways: Transmission Control.
In many cases, this could be the culprit of the code. Found most of wires were just barely hanging on or the insulation was bad around wires. Well i took it home took them off myself and it was done so poorly that i dont know how anything worked. All the codes will be noted including the codes stored in its history and codes that may be pending.

Without electronic throttle control, the driver would notice the deactivation as a sag in performance. Check the ground on the back of the head.
Common Symptoms As with other error codes, this code activates the Check Engine light and registers the code to the system of the vehicle. Thanks for listening to me and hope that this may help someone. Wheel torque is the result of the choice of power sources and the gearing between them and the wheels.

There may be some good ones out there but after 30 years havent seen any so far.
When he hooked it up to the computer it tells him its the gas pedal sensor, so he bought a new one of those and it still does it. Same problem with my03 6. For a typical engine with a redline of 5000 rpm, the sweet spot should be at about 2000 rpm. In practical terms, most engines actually operate in a much broader range between idle and 3200 rpm. It may well be that software integration of automotive electronic systems will turn out to be the most significant automotive technological development of this decade.
I do not have a code reader but when I have got the codes read it has been throttle position mismatch this is the weakest link in my journey on fixing the issue I bought this truck last summer from a ford dealer. Before doing any work on equiptment like this,, a shop manual is best. Mass Air Flow Sensor - unplugged this and the truck ran fine - no code. In this most efficient operating range, the engine produces about 40% of its peak power rating. We use all data for the shop. I changed it after doing all the stuff that was recomended and so far so good, there is a yellow wire going into the tac that brakes alot, mine wasnt. Well guess someone has to keep all these guys employed.
Diagnose current faults first, in the order in which they are stored. Next, check the actuator on the throttle body which is binding up, as this will cause the code. In the Electronic Throttle Body setup, an electric motor called the Throttle Actuator Control Motor is the one that opens and closes the throttle valve. Reducing the output of an engine is accomplished by limiting the airflow into the engine. A mechanic may begin diagnosing this trouble code by removing anything necessary to access the throttle body, throttle position sensor, and throttle body control module.
I realize it is a safety issue. Also, since this code affects the throttle actuator position performance, the vehicle will show no throttle response. The ability to do this is limited by the loss of torque and power that results from these engine settings. Same thing, p1516 , low power. Thanks for all your input.
Truck runs fine - no codes. There may be some good ones out there but after 30 years havent seen any so far. Going back into dealer going to check and clean grounds. Hers gets fixed first:banghead: I let the problem go on figuring I'd deal with it down the road. Four occurrences in the last 3000 miles; very annoying. Where is the location of throttle actuator control module on a v6, 2006 gmc envoy? Going to give them a crack at it if it continues.
