DTC P0133:00

A/F sensor circuit slow response
DETECTION CONDITION
• The PCM monitors the peak differential value of A/F sensor signal after 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
― Absolute load: 21—71% (at engine speed of 2,500 rpm)
― Intake air volume: 5—40 g/s
― Engine coolant temperature: 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.
• DIAGNOSTIC MONITORING TEST RESULTS is available.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• DTCs are stored in the PCM memory.
POSSIBLE CAUSE
• A/F sensor looseness
• Exhaust system leakage
• A/F sensor malfunction
― A/F sensor deterioration
• Fuel pressure sensor malfunction
• Clogged or restricted fuel line
• Fuel leakage in the fuel line between the high-pressure fuel pump and the fuel pump unit
• Fuel pump unit malfunction
• Purge solenoid valve malfunction
• Improper connection purge solenoid hose
• Engine internal malfunction
― Leakage engine coolant to combustion chamber
― Insufficient engine compression
• PCM malfunction
