Conditions for Setting the DTC

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

P0153

The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is more than 0.14 second.
These DTCs set within 60 seconds when the above condition is met.

P0154

The ECM detects that the HO2S 1 parameter is between 400-500 mV.
The Throttle Position (TP) Indicated Angle parameter changes more than 5 percent.
These DTCs set within 101 seconds when the above conditions are met.

P0160

P1153

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

P2272

The ECM detects that the HO2S voltage oscillations are slower than a calibrated value.
DTC P2272 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.

P2273

The ECM detects that the HO2S voltage oscillations are faster than a calibrated value.
DTC P2273 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.

P2A00 or P2A03

P2A01 or P2A04

The ECM 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 ECM detects that the HO2S 2 is more than 751 mV for 8 seconds.
- Rich Intrusive Test-The ECM detects that the HO2S 2 is less than 299 mV for 8 seconds.
DTCs P2A00 and P2A03 set within 2 minutes when the above conditions are met.
The ECM 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.
DTCs P2A00 and P2A03 set within 5 minutes when the above conditions are met.
