DTC P2630 - O2 Sensor Positive Current Trim Circuit Low (Bank 2 Sensor 1)

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
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.
Possible Causes: 
  • UO2SPCT2circuit open
  • UO2SPCT2circuit short to ground
  • Contaminated universal heated oxygen sensor bank 2, sensor (HO2S21)
  • Damaged universal HO2S21
Diagnostic Aids:   
Application  Key On Engine Off  Key On Engine Running  Continuous Memory
