If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2174 fault code. This code indicates a problem with the Throttle Actuator Control (TAC) module, which can be caused by a faulty module, open or shorted harness, poor electrical connection, or carbon build-up on the throttle plate.

It’s important to address this issue promptly as it can affect the performance of your vehicle. The repair time for this fault code is estimated at 1.0, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2174 fault code. Here are the symptoms to look out for:

  • The P2174 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 reduced engine power, poor acceleration, stalling, rough idling, and difficulty starting the engine.
  • Additionally, the vehicle may experience decreased fuel efficiency, increased emissions, and a decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p2174 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 P2174 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.
  • Another cause can be a poor electrical connection in the Throttle Actuator Control (TAC) module circuit.
  • Additionally, the throttle plate sticking due to carbon build-up can also cause this fault code.
  • Finally, the Engine Control Module (ECM) can also be a cause of the P2174 fault code.

To fix the p2174 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2174, 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 fault code P2174 indicates that the engine is running too lean at idle.

This can be caused by a variety of factors, including a faulty oxygen sensor, a vacuum leak, or a clogged fuel injector. The estimated repair time for this issue is 1.0 hour, and most auto repair shops charge between $75 and $150 per hour. The cost of fixing this issue will depend on the specific cause of the problem and the cost of any necessary replacement parts.

The P2174 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. Two processors located within the ECM monitor the TAC system data. The P2174 code indicates a sudden low air flow in the TAC system.

What are the possible causes of the P2174 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2174 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 or broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2174 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a P2174 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.
