Throttle actuator control module performance
This trouble code indicates that the powertrain control module has detected a malfunction with the throttle body control motor or module. This code is only found on vehicles that have an electronic throttle body.
Some potential causes of this trouble code would include:
Symptoms of this trouble code that the driver may experience would include:
The engine may not start or have trouble starting.
The engine may accelerate poorly or not accelerate at all.
The engine may idle incorrectly.
The engine may go into a fail-safe mode which reduces engine power and in some cases will disable the engine completely.
The Check Engine Light will be illuminated.
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.
Once these items are accessible, the mechanic would then reference the manufacturer’s service information to decide how to test the throttle body motor, throttle position sensor, and throttle body control module.
When these tests have been carried out, the mechanic would note their findings and relay them over to the customer to make a repair decision.
Sometimes mechanics can spend hours looking for the throttle position sensor. If this sensor is difficult to find under the hood, remember that sometimes this sensor can actually be a pedal position sensor and may be located in the driver floor area. Keeping this in mind can save a lot of time if the sensor is not on the throttle body.
This code is very serious as it can affect the way the engine performs. With a throttle that is not working properly, there is no way for the engine can perform properly. I would advise having this trouble code diagnosed and repaired as soon as possible because this trouble code can prevent your vehicle from operating at all.
Repairs that can fix this trouble code would include:
Never try to open an electronic throttle body manually. This includes using your hands or any other tool to open the throttle body by force. This will only cause more damage to the throttle system than before. If the throttle motor was not bad before, it very well could go bad after doing something like that.
