Conditions for Setting the DTC
P0131
The engine control module detects that the heated oxygen sensor voltage is less than 0.9 V for more than 2 s.
P0132
The engine control module detects that the heated oxygen sensor voltage is greater than 7.50 V for more than 2 s.
P0133
The engine control module detects that the expected rise in O2 concentration is greater than 3 s or the time from 30% to 60% is greater than 1.8 s.
P11A6

P11A9
The engine control module detects that the difference between the calculated value of O2 concentration and the HO2S signal output is less than 0.06 and 0.07 for 0.1 s.
P2237
The ECM detects the measured O2 concentration is less than 0.01 for more than 2 s.
