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 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. The test fails if the PCM determines the resistance value is too high.
Possible Causes: 
  • UO2SPCT circuit open
  • UO2SPCT circuit short to ground
  • Contaminated or damaged HO2S
Diagnostic Aids: 
Application  Key On Engine Off  Key On Engine Running  Continuous Memory 
All GO to PINPOINT TEST DZ .
RENDER: 1.0x
