Based on the systems affected by this code, we will most likely start with:
P2630
ŚredniOxygen (Lambda) Sensor – Low Pumping Circuit Correction Current, Bank 2, Sensor 1. The ECM/PCM detected too low voltage or insufficient current in the O2 sensor pumping current correction circuit.
OBD-II (EN): O2 Sensor Heater Control Circuit Low Bank 2 Sensor 1
Code P2630 signals a problem with the pumping current correction circuit of the oxygen sensor (lambda probe) on bank 2, sensor 1 (pre-catalyst). The most common cause is a faulty or contaminated O2 sensor, but a damaged wiring harness or fuel pressure problem could also be the culprit. Diagnosis at a service center is recommended – the error can cause increased fuel consumption and emissions.
Symptoms
Check Engine Light (MIL) on Decreased engine performance and power Engine running too lean or too rich Increased fuel consumption Smoke from the exhaust pipe Rough engine running
Possible causes
Faulty oxygen sensor (lambda probe) – bank 2, sensor 1 Carbon buildup (contamination) on the O2 sensor Blown fuses in the sensor circuit Fuel pressure too high or too low Damaged wiring or connectors in the sensor circuit (open, short, corrosion) Faulty ECM/PCM controller (rare)

Does code P2630 require professional diagnostics?
The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
