Code Enable Criteria

For DTC to run, DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0125, P0128, P0201-P0206, P0300, P0410, P0440, P0442, P0443, P0446, P0449, or P1441 are not set. DTC will set when PCM monitors the following conditions for 2 minutes after closed loop enable.

• Less than 55 lean-to-rich and rich-to-lean switches for this HO2S.
• HO2S voltage remains between 300-600 mV.

When DTC is set, PCM will illuminate Malfunction Indicator Light (MIL) on second consecutive ignition cycle that DTC fails. PCM records operating conditions at the time of failure in FREEZE FRAME and/or FAILURE RECORDS data. MIL will turn off after 3 consecutive ignition cycles that DTC does not fail. Current DTC will clear when DTC runs and passes. History DTC will clear after 40 consecutive no fail cycles by this or any other emission related DTC. DTC can also be cleared manually using scan tool.
