Conditions for Setting the DTC

WARNING: This page is about a different variant/trim than selected.

P0131

The control module detects that the HO2S 1 Voltage parameter is less than 25 mV.
DTC P0131 sets within 100 seconds during the lean test when the above condition is met.

P0132

The control module detects that the HO2S 1 parameter is more than 950 mV.
DTC P0132 sets within 15 seconds during the rich test when the above condition is met.

P0137 or P0157 Lean Test

The control module detects that the HO2S 2 voltage parameter is less than 75 mV.
These DTCs set within 100 seconds during the lean test when the above condition is met.

P0138 or P0158 Rich Test

The control module detects that the HO2S 2 voltage parameter is more than 950 mV.
These DTCs set within 100 seconds during the rich test when the above condition is met.

P0151

The control module detects that the HO2S Bank 2 Sensor 1 Voltage parameter is less than 100 mV.
DTC P0151 sets within 3 seconds when the above condition is met.

P0152

The control module detects that the HO2S Bank 2 Sensor 1 Voltage parameter is more than 950 mV.
DTC P0151 sets within 3 seconds when the above condition is met.

P2A00 or P2A03

P2A01 or P2A04

The control module detects that the HO2S 2 did not transition below 299 mV and above 751 mV during the passive test.
One of the following tests fail once per trip/runs until pass or fail reporting:
- Lean Intrusive Test-The control module detects that the HO2S 2 is more than 751 mV for 8 seconds.
- Rich Intrusive Test-The control module detects that the HO2S 2 is less than 299 mV for 8 seconds.
These DTCs set sets within 2 minutes when the above conditions are met.

The control module detects that the Loop Status parameter is open by not meeting the voltage criteria to enable close loop fueling.
Voltage cannot be between 250-600 mV for 10 seconds after the O2 has seen a ready to go closed loop command.
These DTCs set within 5 seconds when the above condition is met.
