Code P2626 Hyundai Description
The P2626 diagnostic trouble code for Hyundai vehicles refers to an issue with the HO2S (Heated Oxygen Sensor) Pumping Current Trim Circuit/Open on Bank 1 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gases and transmitting this data to the engine control module (ECM) for proper air-fuel ratio adjustments. The pumping current trim circuit/open error indicates a problem with the circuit that controls the sensor's pumping current or an open circuit in the sensor itself.
Common Causes of P2626 Hyundai
- Faulty HO2S (Heated Oxygen Sensor)
- Damaged wiring or connectors in the sensor circuit
- ECM software issues
- Exhaust leaks near the sensor
- Engine coolant leaks contaminating the sensor
Symptoms of P2626 Hyundai
- Decreased fuel efficiency
- Engine misfires
- Rough idling
- Loss of power
- Illumination of the check engine light
