How does the GM Electronic throttle body work?
Let’s find out how the throttle body works in this system in the next subheading. How Does The GM Electronic Throttle Body Work? The Throttle Actuator Control (TAC) Module is the brain behind the Electronic Throttle Control System in the GM 4.8L, 5.3L, and 6.0L engines covered by this article.
Where is the throttle actuator control ( TAC ) module located?
The Throttle Actuator Control (TAC) Module is the brain behind the Electronic Throttle Control System in the GM 4.8L, 5.3L, and 6.0L engines covered by this article. The TAC Module is not part of the internal workings of the PCM and is usually located on the driver side of the firewall.
How does the spark control work on an ECM?
On some ECM they have an IAT Incoming Air Temperature sensor in the air cleaner or MAT Manifold Air Temperature sensor in intake manifold. 13. ESC = Electronic Spark Control. This sends the signal from the Knock sensor to the ECM to reduce the timing if it hears a knock. 14. VSS = Vehicle Speed Sensor. VSS sends the ECM the cars speed.

How to do throttle body re-Learn Chevy Malibu?
1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light.
How does the throttle actuator control module work?
The Throttle Actuator Control (TAC) Module receives input from the accelerator pedal position sensors in the accelerator pedal Assembly (inside the pickup or SUV). The potentiometers in the Accelerator Pedal Assembly are what tell the TAC Module how much you want to accelerate the engine.
Where are the wires located on the throttle body?
When looking down at the Electronic Throttle Body’s connector, the top row (from left to right) has 4 wires which are labeled from A to D (see photo). The second row (bottom row) from left to right, the wires are labeled E to H (see photo). and here are their specific descriptions: A: (Yellow wire) TAC Motor Control -1.
How to relearn the throttle on a Chevy Silverado?
1. Remove negative battery cable for 20 minutes to reset all DTCs. 2. Start engine, run in park for 3 minutes -Engine starts at about 1200rpm, then slowly idles down to 800 rpm and back up to a steady 1000rpm 3. Remove key for 60 seconds 4.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.

How does the throttle plate work on a GM car?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position.
Where is the throttle position sensor on a Chevy 6.0?
Throttle body sensor failure – Chevy 6.0 The throttle position sensor (TPS) is located on the throttle body and is responsible for controlling air flow into the engine. The TPS sensor monitors how open the throttle is (ie. how much air is entering the engine) and relays the information back to the ECU.
What happens if the electronic throttle fails in a car?
The electronic throttle body is controlled by the computer engine of the vehicle in modern cars. So, if the throttle body fails then, the computer engine controls it and interrupts from moving the valve and, consequently, helps to save the whole engine from any extensive damage. And then, the engine seems to have very poor idling.
When is a bad throttle position sensor a warning sign?
Engine won’t idle smoothly, idles too slowly, or stalls If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS. You don’t want to wait to get this checked out!
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.
How many wires are in the throttle body?
As you have probably already observed, there are 8 wires sticking out of the Electronic Throttle Body. When looking down at the Electronic Throttle Body’s connector, the top row (from left to right) has 4 wires which are labeled from A to D (see photo). The second row (bottom row) from left to right, the wires are labeled E to H (see photo).
What happens if a Chevy 6.0 engine goes wrong?
In case any of these go wrong, an engine can misfire. There are quite grave consequences when a Chevy 6.0 engine misfires. The engine could get damaged even more, or you might experience more emissions or witness lesser fuel efficiency. This issue is known to be there in various Chevrolet models.
