If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2627 fault code. This code indicates a problem with the Heated Oxygen Sensor (HO2S) or its related wiring harness and connectors. The cause could be a faulty HO2S, an open or shorted HO2S harness, or a poor electrical connection in the HO2S circuit.

It is important to visually inspect the wiring harness and connectors for any damage or corrosion. The repair time for this fault code is estimated at 1.0. To interpret the fault code, check the “Possible Causes” listed above and follow the recommended fix.

Repair Importance Level10.0 (Out of 10)
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 p2627 fault code.

Here are the symptoms to look out for:

  • The P2627 fault code in an automobile 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, decreased fuel efficiency, engine misfires, and rough idling.
  • Additionally, the vehicle may experience stalling or hesitation during acceleration, and there may be a noticeable 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 P2627 can be caused by a faulty HO2S, open or shorted HO2S harness, or poor electrical connection.

  • The automobile fault code P2627 can be caused by a faulty Heated Oxygen Sensor (HO2S).
  • It can also be caused by an open or shorted Heated Oxygen Sensor (HO2S) harness.
  • Additionally, a poor electrical connection in the Heated Oxygen Sensor (HO2S) circuit can also trigger this fault code.

To fix the automobile fault code p2627, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2627, 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 P2627 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 diagnosis and fixing the P2627 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 P2627 code is related to the Universal Heated Oxygen Sensor (HO2S) connector.

A resistor is installed in the connector to account for part to part variance. The Powertrain Control Module (PCM) determines the value of this resistor by taking multiple measurements during each ignition ON event. If the PCM determines the resistance value is too high, the test fails and the P2627 code is triggered.

This code indicates an issue with the Oxygen Sensor Pumping Current Trim Circuit on Bank 1 Sensor 1.

What are the possible causes of the P2627 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2627 fault code. This code is usually caused by a faulty Heated Oxygen Sensor (HO2S), an open or shorted HO2S harness, or a poor electrical connection in the HO2S circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
