Conditions for Setting the DTC

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

P0131

The engine control module detects that the heated oxygen sensor pump current or reference voltage circuit is shorted to ground for greater than 4 s.

P0132

The engine control module detects that the heated oxygen sensor pump current, reference voltage, or reference ground circuit is shorted to voltage for greater than 4 s.

P015A or P015B

The engine control module detects that the heated oxygen sensor rich-to-lean or lean-to-rich average response time is greater than a calibrated value.
The DTCs set within 60 s when the above condition is met.

P223C

The engine control module detects an open circuit fault to the pump current, reference voltage, reference ground, or trim circuit or a trim circuit short to ground, by detecting that the pump current is less than 0.10 mA or greater than 4.18 mA for greater than 7 s..

P223E

The engine control module detects that the heated oxygen sensor reference cell is colder than 700°C (1292°F) or warmer than 1000°C (1832°F) for greater than 4 s.
