DTC P0133 - O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)

DTC DESCRIPTION P0133 - O2 SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 1)

Description:  The oxygen sensor response time is monitored while commanding a calibrated fuel control routine. This routine sets the air fuel ratio to a calibrated limit to produce a predictable oxygen sensor signal amplitude. This DTC sets when the oxygen sensor signal does not reach the predicted amplitude within a predetermined response time.
Possible Causes: 
  • Contaminated universal HO2S
  • Exhaust leaks
  • Incorrect fueling
  • Mass airflow (MAF) sensor
  • Intake air system leaks
  • Damaged universal HO2S
Diagnostic Aids:  Access the HO2S test results from the scan tool to verify the DTC.
