If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2173 fault code.

Here are the symptoms to look out for:

  • The P2173 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience poor acceleration, reduced fuel efficiency, and increased emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p2173 can be caused by a range of issues, including a faulty Throttle Actuator Control module and a sticking throttle plate due to carbon build-up.

  • The automobile fault code P2173 can be caused by a faulty Throttle Actuator Control (TAC) module.
  • It can also be caused by an open or shorted Throttle Actuator Control (TAC) module harness.
  • Poor electrical connection in the Throttle Actuator Control (TAC) module circuit can also trigger this fault code.
  • Another cause is the throttle plate sticking due to carbon build-up.
  • Lastly, the Engine Control Module (ECM) can also be a cause of the P2173 fault code.

To fix the p2173 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2173, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that all the connections are secure and tight.
  • This repair process takes an estimated time of 1.0 hour.

The fault code P2173 indicates a problem with the throttle actuator control system.

The diagnosis involves checking the wiring, connectors, and the throttle body itself. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the hourly rate of the auto repair shop.

Most shops charge between $75 and $150 per hour. Therefore, the total cost of fixing the P2173 fault code can range from $75 to $150.

The P2173 code is related to the Throttle Actuator Control (TAC) system. The Engine Control Module (ECM) is responsible for controlling the TAC system. The ECM calculates the appropriate throttle response based on the driver’s intent.

The TAC system uses two circuits for motor control, and two processors are used to monitor the TAC system data. These processors are located within the ECM. They monitor each other’s data to ensure that the indicated throttle position is correct.

The P2173 code indicates that there is high air flow in the Throttle Actuator Control System. This can cause issues with the TAC system and affect the throttle response.

It is important to have this issue diagnosed and repaired as soon as possible to avoid further damage to the vehicle.

What are the possible causes of the P2173 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2173 fault code. This code is caused by a faulty Throttle Actuator Control (TAC) module, an open or shorted TAC module harness, a poor electrical connection in the TAC module circuit, a throttle plate sticking due to carbon build-up, or an Engine Control Module (ECM). To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2173 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a P2173 fault code, it could be caused by a faulty Throttle Actuator Control (TAC) module, a poor electrical connection, or a sticking throttle plate due to carbon build-up. To fix this issue, check the “Possible Causes” listed above and visually inspect the related wiring harness and connectors.
