Conditions for Setting the DTC

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

P0133

The ECM detects that the HO2S 1 rich-to-lean or lean-to-rich average response time is more than 0.14 second.
DTC P0133 sets within 60 seconds when the above condition is met.

P0134

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.
DTC P0134 sets within 101 seconds when the above conditions are met.

P0140

P1133

The ECM detects that the HO2S 1 rich-to-lean counts, or the lean-to-rich counts are less than a calibrated value.
DTC P1133 sets within 60 seconds when the above condition is met.

P2270

The ECM detects that the HO2S 2 voltage oscillations are slower than a calibrated value.
DTC P2270 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.

P2271

The ECM detects that the HO2S 2 voltage oscillations are faster than a calibrated value.
DTC P2271 sets within 4 seconds when the above condition is met continuously, or within 50 seconds when the above condition is met cumulatively.

P2A00

P2A01

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.
DTC P2A01 sets 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.
DTC P2A01 sets within 5 seconds when the above condition is met.
