What Does The Throttle Actuator Control Module Do? An idle speed control actuator is controlled by an idle speed control actuator solenoid. This solenoid is controlled by a control module. When this solenoid is turned off, no vacuum is routed to the idle speed control actuator, allowing it to open the throttle slightly to increase idle speed.
What happens when the electronic throttle control goes bad? When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.
How much does it cost to replace a throttle actuator control system? The system controls the air-fuel mixture that goes into the engine. The average cost for a throttle body replacement is between $577 and $691. Labor costs are estimated between $92 and $117 while parts are priced between $485 and $574.
What is a throttle actuator control? The Throttle Actuator Control (TAC) system uses 2 Throttle Position (TPS) sensors to monitor the throttle position. The TP sensors 1 and 2 are located within the throttle body assembly. Each sensor has the following circuits: A 5-volt reference circuit. A low reference circuit.
What Does The Throttle Actuator Control Module Do? – Related Questions
Can you drive with a bad electronic throttle control?
If you have a bad throttle position sensor, your car will not perform well or safely. Driving with a bad throttle position sensor may also cause problems in other related systems in your car, which will mean additional repair bills.
How do you know if your electronic throttle control is bad?
When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).
How do I clean my throttle actuator control?
How to Clean a Throttle Body
Disconnect the air duct. Disconnect the air duct from the throttle body.
Spray on a throttle body cleaner. Locate the throttle cables and rotate the throttle plate.
Dry off the solvent. Shoot compressed air into the throttle body to dry the spray solvent.
How do you fix a throttle actuator control system stuck open?
What repairs can fix the P2111 code
Can throttle control make car not start?
Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn’t step on the gas.
Where is the throttle actuator control module?
The TAC module is mounted on the driver’s side firewall under the corner brace.
Where is the throttle actuator located?
These devices control the volume or amount of air that enters the engine via the driver’s accelerator pedal. A throttle actuator is held to the intake manifold using three or four bolts sealed with a gasket, a computer wiring harness connector is directly plugged into the actuator.
How much does a throttle actuator cost?
To replace your car’s throttle body, you will pay as little as $370 or as much as $1,500. Labor should be between $70 and $260, and parts should cost you from $110 to $600.
How do I reset my electronic throttle control?
Resetting your electronic throttle control manually can be a tricky job. First, make sure the accelerator pedal is fully released. Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation.
What happens if you disconnect throttle position sensor?
If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration.
How much does it cost to replace a throttle position sensor?
The average cost for throttle position sensor replacement is between $164 and $179. Labor costs are estimated between $54 and $68 while parts are priced at $110. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Can a bad throttle body cause transmission problems?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems. When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle.

What are the signs of a bad throttle body?
Here are the most common signs a failing throttle body we’ve seen in our shop:
Grime buildup. Dirt and grime can build up inside the part’s housing (some mechanics call this “coking”) causing an interruption in air-fuel flow.
Electrical problems.
Airflow disruptions.
Poor or high idle.
The ominous check engine light.
Should I clean or replace throttle body?
While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability. In fact, if you’ve noticed a rough idle, stumbling initial acceleration or even stalling – all when the engine is fully warmed up – a dirty throttle body could be the culprit.
How do you reset throttle position sensor?
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Can I use WD40 to clean my throttle body?
WD40 won’t be an effective throttle body cleaner, hard deposits stuck to the throttle body and throttle plate will require a throttle body solvent. Throttle body cleaner is formulated to help breakdown carbon and other fuel related deposits on a throttle body.
