The P2101 automobile fault code is a common issue that can cause the engine light to turn on or the service engine soon warning light to appear.

The main symptom of this fault code is the lack of throttle response. The possible causes of this issue include a binding or bent throttle plate, a faulty throttle body assembly, a shorted or open throttle body assembly harness, a poor electrical connection in the throttle body assembly circuit, or a faulty engine control module (ECM). The repair time for this issue is estimated to be around 1.0, and it is important to visually inspect the related wiring harness and connectors to check for damaged components and broken, bent, pushed out, or corroded connector’s pins.

If you’re experiencing an illuminated engine light and a lack of throttle response, read on to learn more about the symptoms of the p2101 automobile fault code.

  • The P2101 fault code in an automobile can cause the following symptoms: the engine light will turn on or the service engine soon warning light will appear.
  • Additionally, there will be no throttle response, meaning that the accelerator pedal will not cause the vehicle to accelerate.
  • These symptoms can be frustrating and dangerous, as the driver may not be able to control the speed of the vehicle.
  • It is important to address this issue as soon as possible to ensure the safety of the driver and passengers.

P2101 fault code in automobiles can be caused by various factors, including a binding or bent throttle plate, faulty throttle body assembly, and more.

  • The automobile fault code P2101 can be caused by a binding or bent throttle plate.
  • It can also be caused by a faulty throttle body assembly or a throttle body assembly harness that is open or shorted.
  • Additionally, a poor electrical connection in the throttle body assembly circuit can cause this fault code.
  • Finally, a faulty engine control module (ECM) can also be a cause of the P2101 fault code.

To fix the p2101 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2101, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2101 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of fixing the P2101 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2101 code is related to the throttle actuator control motor circuit.

The Engine Control Module (ECM) calculates the appropriate throttle response based on the throttle position sensors.

The ECM controls the throttle valve by applying a varying voltage to the control circuits of the Throttle Actuator Control (TAC) motor.

The ECM monitors the duty cycle that is required to actuate the throttle valve. The DTC will be set when the ECM detects the actual throttle position does not match the predicted throttle position for greater than 1 s.

What are the possible causes of the P2101 automobile fault code?

If you’re experiencing a lack of throttle response and the engine light is on, it could be due to the P2101 fault code. This code is often caused by a binding or bent throttle plate, a faulty throttle body assembly, or a poor electrical connection in the throttle body assembly circuit. It could also be due to a faulty engine control module. To fix this issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2101 fault code?

To fix the P2101 fault code, start by checking the possible causes listed above. Then, visually inspect the related wiring harness and connectors for any damage or broken, bent, pushed out, or corroded pins. This will help identify if the issue is caused by a binding or bent throttle plate, faulty throttle body assembly, open or shorted throttle body assembly harness, poor electrical connection in the throttle body assembly circuit, or a faulty engine control module (ECM).

Is a faulty Engine Control Module (ECM) a common cause of the P2101 fault code?

While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2101 fault code, it is not a common cause. The code is more likely to be triggered by a binding or bent throttle plate, faulty throttle body assembly, or poor electrical connection in the throttle body assembly circuit. To fix the issue, it is recommended to visually inspect the related wiring harness and connectors, and check for damaged components and connector pins.
