DTC P2627: O2 SENSOR PUMPING CURRENT TRIM CIRCUIT LOW BANK 1, SENSOR 1
| Description: | A resistor is installed in the universal heated oxygen sensor (HO2S) connector for part to part variance. The PCM determines the value of this resistor by taking multiple measurements of the resistor during each ignition ON event. The PCM uses this value in order to compensate for the variance in the pumping current signal. This DTC sets when the PCM determines the resistance value is too high. | ||
