P2297 - O2 SENSOR OUT OF RANGE DURING DECELERATION (BANK 1, SENSOR 1)

Description:  During a deceleration fuel shut-off (DFSO) event, the powertrain control module (PCM) monitors how quickly the rear heated oxygen sensor (HO2S) switches from rich to lean. The measured rate of the rich to lean switch is compared to a calibrated threshold value. The threshold value takes into account the level of oxygen in the catalyst, which has an impact on how quickly the rich to lean switch occurs. The test fails when the measured value is slower than the threshold value.
Possible Causes: 
  • Exhaust leaks before or near the HO2S
  • Damaged HO2S
Diagnostic Aids:  Check for leaks in the exhaust system.
Application  Key On Engine Off  Key On Engine Running  Continuous Memory
