Where is the TAC located in a GM 4.8l engine?
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.
Is it normal to have no go at full throttle?
Because if it’s an A/T, and you get high revs and no go at full throttle. That’s normal. But if your engine is not putting out then I would go through the check list above. If it’s not any of that stuff have a quality mechanic preform a 5 star check on it.

Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component. Diagnostic trouble codes P0120, P0121, P0122, P0123, and P0124 are what will commonly appear. The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM.
How does the accelerator pedal work in a car?
Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor. This sensor’s primary job is to monitor the position of the throttle pedal and send an electronic signal to open the throttle body as you depress the gas pedal.
How is the gas pedal connected to the throttle body?
Many car makers including GM started installing fly by wire electronic throttle bodies. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting.

How is the throttle body connected to the PCM?
The throttle body is linked with a throttle body position sensor which collects information regarding the amount of air entering the intake. The sensor then transfers this information to the PCM which decides how much fuel should be mixed for an effective combustion process.
Why do you need a throttle body on a jeep?
A throttle body controls the airflow in to your Jeep’s engine. As you depress the accelerator pedal, the butterfly valve opens to allow more air to enter the engine. Upgrading the original throttle body to a larger one can allow for more horse power to be made.
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).

There are three major components of the GM Electronic Throttle Body and they are: Throttle body. Throttle Actuator Control (TAC) module. And Accelerator Pedal Assembly. In this section, we’ll focus on the Electronic Throttle Body.
How is a throttle body like a carburetor?
Like a carburetor a throttle body controls the amount of air that enters an engine for a given RPM. However, unlike the carburetor a throttle body does not direct fuel into the motor as instead a direct port electronic fuel injector sprays fuel into each cylinder.
How much horsepower will a performance throttle body add?
How much Horsepower will a performance Throttle Body add?
