[SOLVED] P2630 Code: Fix Low Oxygen Sensor Pumping Current In Bank 2

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2630 fault code.

This code indicates a problem with the Heated Oxygen Sensor (HO2S) or its related wiring harness and connectors. The HO2S is responsible for monitoring the oxygen level in the exhaust and providing feedback to the engine control module. A faulty HO2S or poor electrical connection can cause the engine to run poorly, reduce fuel efficiency, and increase emissions.

The repair for this fault code involves visually inspecting the wiring harness and connectors for damage and checking for broken or corroded pins. The repair time for this code is estimated at 1.0.

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 a sign of p2630 fault code.

Here are the symptoms to look out for:

  • The P2630 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 a decrease in engine power, reduced fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code P2630 can be caused by a faulty HO2S, open or shorted HO2S harness, or poor electrical connection.

  • The automobile fault code P2630 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.

Below are the possible fixes for the automobile fault code p2630, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2630, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for 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 P2630 indicates an issue with the Fuel Pump ‘A’ Low Flow Performance. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue is dependent on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2630 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. The PCM uses this value to compensate for the variance in the pumping current signal.

If the PCM determines the resistance value is too high, the test fails and the P2630 code is triggered. This code specifically refers to the Oxygen Sensor Pumping Current Trim Circuit Low Bank 2 Sensor 1.

What are the possible causes of the P2630 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2630 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.
