P2628

DTC P2628, sometimes indicated as P262800 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing o2 sensor pumping current trim circuit high bank 1 sensor 1.

This code means that the oxygen sensor pump current trim circuit is high. This could be caused by a variety of things, including a defective oxygen sensor, a wiring problem, or a problem with the engine control unit.
If this code is stored, the first step is to check the oxygen sensor for proper function. If it is found to be defective, it will need to be replaced. If the problem is with the wiring, the wiring should be checked and repaired as necessary. If the problem is with the engine control unit, it will need to be serviced.
