Conditions for Setting the DTC

P0133

• The ECM detects that the HO2S1 average response time is greater than a calculated value.
• DTC P0133 sets within 60s when the above condition is met.

P013A 

The ECM detects that the accumulated mass air flow monitored during rich-to-lean transitions between 450-150mV is greater than a calibrated value.

P013B 

The ECM detects that the accumulated mass air flow monitored during lean-to-rich transitions between 300-600mV is greater than a calibrated value.

P013E 

The ECM detects that the O2 sensor cannot achieve voltage below 450mV within a calibrated value of accumulated air flow.

P013F 

The ECM detects that the O2 sensor cannot achieve voltage above 300mV within a calibrated value of accumulated air flow.

P015A

• The ECM detects that the length of time to change from rich to lean is greater than a calibrated value.
• DTC P015A sets within 60s when the above condition is met.

P015B

• The ECM detects that the length of time to change from lean to rich is greater than a calibrated value.
• DTC P015B sets within 60s when the above condition is met.

P2270

• The ECM detects that the O2 sensor cannot achieve voltage equal to or more than 775mV.

  AND

• The ECM detects that the accumulated mass air flow monitored during the Stuck Lean Voltage Test is more than a calibrated value.

P2271

• The ECM detects that the O2 sensor cannot achieve voltage equal to or less than 100mV.

  AND

• The ECM detects that the accumulated mass air flow monitored during the Stuck Rich Voltage Test is more than a calibrated value.
