Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2171 fault code.

Here are the symptoms to look out for:

  • The P2171 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.

P2171 fault code can be caused by various issues, including a faulty exhaust pressure regulator vent solenoid and poor electrical connection.

  • The automobile fault code P2171 can be caused by a faulty Exhaust Pressure Regulator Vent Solenoid.
  • It can also be caused by an open or shorted Exhaust Pressure Regulator Vent Solenoid harness.
  • Additionally, a poor electrical connection in the Exhaust Pressure Regulator Vent Solenoid circuit can also trigger this fault code.
  • These are the three main causes of the P2171 automobile fault code.

To fix the p2171 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2171, 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.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2171 indicates that the engine is running too lean.

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, as well as the labor rates of the repair shop.

It is important to address this issue promptly, as running the engine too lean can cause damage to the vehicle over time.

The P2171 code is a generic description for the Exhaust Pressure Regulator Vent Solenoid Control Circuit High. However, the manufacturer may have a different description for your specific vehicle model and year.

What are the possible causes of the P2171 fault code?

If you notice the engine light on or the service engine soon warning light, it could be due to the P2171 fault code. This code is caused by a faulty exhaust pressure regulator vent solenoid, an open or shorted harness, or a poor electrical connection in the solenoid circuit. To fix this issue, you should 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 P2171 fault code?

If you’re experiencing the P2171 fault code with the engine light on, it could be due to a faulty exhaust pressure regulator vent solenoid or a poor electrical connection. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for any damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any open or shorted circuits and ensure that the electrical connection is secure.

What are the signs that the Exhaust Pressure Regulator Vent Solenoid circuit has a poor electrical connection causing the P2171 fault code?

If the Exhaust Pressure Regulator Vent Solenoid circuit has a poor electrical connection, it can cause the P2171 fault code, which triggers the Engine Light ON or Service Engine Soon Warning Light. To fix this issue, you need to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. It is important to check the “Possible Causes” listed above to ensure that the Exhaust Pressure Regulator Vent Solenoid is not faulty or the harness is not open or shorted.
