P2626

O2 Sensor Pumping Current Trim Circuit/Open Bank 1 Sensor 1

DTC P2626, sometimes indicated as P262600 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/open bank 1 sensor 1.

This code is set when the O2 sensor pumping current trim circuit is open.
This code can be caused by a variety of things, including a bad O2 sensor, a bad wiring harness, or a bad ECM.
The best way to determine the cause of this code is to use a diagnostic scanner to read the O2 sensor pumping current trim value. If this value is not within the normal range, then the problem is likely with the O2 sensor or the wiring harness. If the value is normal, then the problem is likely with the ECM.
