DTC P0133:00

A/F sensor circuit slow response
DETECTION CONDITION
•  The PCM monitors the peak differential value of the oxygen sensor signal after the A/F fluctuation being provided when the following conditions are met. If the peak differential value is lower than the threshold value.
•  The PCM determines that the A/F sensor circuit is slow.
MONITORING CONDITIONS
―  Drive Mode 03 (EGR System, A/F Sensor Heater, HO2S Heater, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)
―  The following conditions are met:
•  A/F sensor heater monitor is completed.
•  Fuel system loop status is closed loop fuel control.
―  Engine speed: 1,350—3,500 rpm
―  Charging efficiency: 15—63 % (at engine speed 2,500 rpm)
―  Intake air volume: 5—40 g/s
―  ECT: above 70 °C {158 °F}
Diagnostic support note
•  This is an intermittent monitor (A/F sensor, HO2S).
•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  The DTC is stored in the PCM memory.
