P2631: Affordable Fix For Complex Automobile Fault Code
The automobile fault code P2631 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 P2631 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
P2631: Your Car’s Fuel Pump Control Circuit – Explained
The P2631 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 P2631 code is triggered. This code indicates an issue with the Oxygen Sensor Pumping Current Trim Circuit High Bank 2 S.
FAQ
If you’re experiencing the P2631 fault code, you may notice that your engine light is on. This code is typically 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 the issue, it’s important to visually inspect the wiring harness and connectors, checking for any damaged components or broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to 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, start by visually inspecting the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and determine the necessary steps to resolve them.
Ignoring the P2631 fault code can lead to serious consequences such as reduced fuel efficiency, engine misfires, and damage to the catalytic converter. The fault code is caused by a faulty Heated Oxygen Sensor (HO2S) or a poor electrical connection in the HO2S circuit.
