P2630: The lambda sensor pumping current trim (bank 2
The lambda sensor pumping current trim (bank 2, sensor 1) gives a lower signal than normal. It is usually the sensor itself, its wiring or a real fault in what it measures.

How to read and clear P2630 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2630 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

What does code P2630 mean?
The lambda sensor pumping current trim (bank 2, sensor 1) gives a lower signal than normal. It is usually the sensor itself, its wiring or a real fault in what it measures.
How do you clear P2630?

Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
