P2630 - OBD Trouble Code

<<See All OBD Codes

You may have been struggling with your car for some time before figuring out that there’s some error. The OBD codes help us understand what exactly is causing issues with the vehicle, and the P2630 code is defined as an O2 Sensor Pumping Current Trim Circuit Low. Don’t worry if that doesn’t really make sense the first time you read it; a lot of people aren’t able to. In simple language your vehicles oxygen sensor is not working as needed by the Powertrain Control Module (PCM). The purpose of the error code is to help the driver fix the issue, in order to avoid further damage to the engine and other components. To know more read along.

This generic code is pertaining to a problem with the oxygen sensor. The job of the oxygen sensor is to measure the amount of oxygen in the exhaust gasses once they have left the combustion process of the engine. This information is then passed on to the PCM, the PCM uses this information to maintain good fuel economy for your vehicle. The p2630 code signifies that the O2 sensor pumping current trim circuits present in a particular engine bank have produced a signal that is not in the correct range. Bank 2 here refers to the affected engine bank which doesn’t have cylinder number 1 and sensor 1 refers to the faulty sensor present in the upstream of the catalytic converter. When the PCM has detected a failure of the oxygen sensor it will set the P2630 code.

What causes this problem with the O2 Sensor Pumping Current Trim Circuit Low B2S1?

• Fault with the Heated Oxygen Sensor (HO2S)
• The harness of the Heated Oxygen Sensor (HO2S) is open or shorted
• There’s poor electrical connection of the Oxygen Sensor (HO2S) circuit

1. O2 Sensor - Is the sensor responsible for making note of the amount of oxygen present in the exhaust gases after the combustion process has taken place. A faulty O2 sensor is the main reason for the P2630 code to set. Fix this issue by repairing or replacing the sensor easily with PartsAvatar. We offer free shipping on orders over CAD $99.
2. Oxygen Sensor Electrical Connector - Are electrical component that helps transfer the information to the PCM regarding the amount of oxygen present in the exhaust gases. If the connector is damaged or faulty simply repair it. If that doesn’t help with getting rid of the P2630 code you will have to opt for replacement. Choose from a wide range of brands and prices of connectors on our website. You can chat with our customer care executive available 24/7 in assisting you to find the best one for your vehicle.
3. Oxygen Sensor Fuse/Relay - Electronic components that are in use all the time tend to deteriorate with time. If you have found an issue with the relay you will have to find a replacement for it. Search on our website to easily find the one suited for your vehicle. Order online and track your shipment till it reaches you in just a matter of days!
4. Powertrain Control Module - Is the processing unit of your vehicle. All the information from the Oxygen sensor gets passed on to the PCM. A problematic PCM can cause the P2630 code to set. So, try to repair the issues, or replace the entire PCM. Find the perfect fitment for your vehicle at PartsAvatar, and order online easily.
5. Diagnostic Tools - These are the tools you will need to diagnose and fix the P2630 code. If you need a replacement of a tool you already have search easily on our website, or simple order all the ones you need from the comfort of your home and have them delivered to your doorstep!

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on a few common symptoms of OBD error code P02CC.

Common Symptoms

• Your vehicle isn’t performing well, and is not getting better
• The engine is running lean
• The engine is running rich
• The Check Engine Light is on
• You are able to see smoke coming out of the tailpipe
• Increase in fuel consumption

To correct this issue, you might need to undergo few repairs or replacements for the defective parts such as:

• Confirm the code is valid and not intermittent.
• Inspect the Electrical connector for any damages, repair or replace as needed
• All wiring and harnesses as well as circuitry that is damaged will have to be checked for repairs or replacements
• Inspect and thoroughly clean the HO2S
• Complete failure of the HO2S requiring a replacement

Not only that we also have in stock the best in range auto parts and that too at the most budget friendly prices ever online. Whether you need an O2 Sensor, Electrical Connector, Oxygen Sensor Fuse, PCM, you can simply rely on us for quality auto parts.

Here are some steps which you should follow in order to diagnose this fault code P2630:

• Start by getting all the tools required for the diagnosis, you will need a diagnostic scanner, digital volt/ohmmeter (DVOM), and a source of vehicle specific diagnostic information. Using the vehicle information source, you can get the Technical Service Bulletin and match the code to the symptoms exhibited by your vehicle. Make sure you match your vehicle's make, model, engine correctly with the TSB. The TSB will be a great source of information for locating various components and parts through the diagnosis procedure.
• It’s time to connect the scanner to the diagnostic port of your vehicle and retrieve all the codes present and freeze frame the data. Make a note of it too, these will help you understand if there’s an intermittent condition present as well. Once you have done that you can proceed to clearing the codes and taking your vehicle for a test drive. If the PCM enters readiness mode then you’re likely having an intermittent condition, these unfortunately need to worsen to be able to accurately diagnose them. If the code rests you can continue your diagnosis.
• Inspect all the electrical components connected to this system, you may find damaged connector or bent pins of the connectors, fuses may have also become chafed or broken, repair all of these. If that doesn’t resolve the error code, then replace them.
• Now continue your examination, by checking the oxygen sensor itself for any problems. Repair or replace as needed.
• Using the DVOM carry out voltage tests to see if they’re within the specifications prescribed by the manufacturer in its manual. In order to locate any of the electrical components or parts, simply take help from the TSBs.

Common Mistakes When Diagnosing the P2630 Code

• Not following the diagnostic steps correctly
• Replacing the sensor before cleaning it to see if the problem was due to the presence of contaminants and debris
• Failed PCM
• Wiring issue
