Code P2626 MINI Description
This function shall be triggered only if one of the following diagnosis is active (to set the readiness bit), which are 'Upstream Oxygen Sensor - Signal Monitoring During Fuel Cut-off' and 'Upstream Oxygen Sensor - Heater Monitoring'. The function shall go to the state = “active” only if one of the above diagnosis detected a fault.
If the sensor shows an augmented gain, i.e. the sensor signal is higher than the nominal characteristic line, the plausibility test during the fuel cutoff phase shall detect this symptom (signal voltage above e.g. 5,6 V *) during fuel cut off) and an Open Circuit is assigned to the line, Trim Current.
What are the Possible Causes of the DTC P2626 MINI?
- Faulty Upstream Oxygen Sensor Bank 1
- Upstream Oxygen Sensor Bank 1 harness is open or shorted
- Upstream Oxygen Sensor Bank 1 circuit poor electrical connection
How to Fix the DTC P2626 MINI?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2626 MINI code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
