DTC P2630 - O2 Sensor Positive Current Trim Circuit Low (Bank 2 Sensor 1)
WARNING: This page is about a different variant/trim than selected.
DTC DESCRIPTION P2630 - O2 SENSOR POSITIVE CURRENT TRIM CIRCUIT LOW (BANK 2 SENSOR 1)
| Description: | A resistor is installed in the universal heated oxygen sensor (HO2S) connector for part to part variance. The powertrain control module (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. | ||
