Conditions for Setting the DTC

P0133

• The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is more than 0.1 second.
• DTC P0133 sets within 60 seconds when the above condition is met.

P0134

• The ECM detects that the HO2S 1 parameter is between 400-500 mV for 100 seconds.
• The Throttle Position (TP) Indicated Angle parameter changes more than 1 percent, 3 times.
• DTC P0134 sets within 100 seconds when the above conditions are met.

P0140

• The ECM detects that the HO2S 2 parameter is between 425-475 mV.
• The TP Indicated Angle parameter changes more than 1 percent 3 times.
• DTC P0140 sets within 100 seconds when the above conditions are met.

P1133

• The ECM detects that the HO2S 1 rich-to-lean counts, or the lean-to-rich counts are less than a calibrated value.
• DTC P1133 sets within 60 seconds when the above condition is met.

P2A00

• The ECM detects that the Loop Status parameter is open.
• DTC P2A00 sets within 50 seconds when the above condition is met.

P2A01

1. The ECM detects that the HO2S 2 did not transition below 300 mV and above 700 mV during the passive test.
2. One of the following tests fail:

   Lean Intrusive Test

   • The ECM detects that the HO2S 2 is more than 300 mV for 12 seconds.
   • The HO2S 1 is less than 350 mV.

   Rich Intrusive Test

   • The ECM detects that the HO2S 2 is less than 700 mV for 12 seconds.
   • The HO2S 1 is more than 600 mV.
3. DTC P2A01 sets within 7 minutes when the above conditions are met.
