The MIL is activated after a fault is detected on two consecutive OBD II drive cycles.

Measuring the current going through the heater circuit.

An HO2S heater circuit fault is determined by turning the heater on and off and looking for a corresponding change in the OSM and by.

A sample of the upstream HO2S signal is evaluated to determine if the sensor is capable of switching or has a slow response rate.

A fixed frequency closed loop fuel control routine is executed and the upstream HO2S voltage amplitude and output response frequency are observed.

, the HO2S-11 indicated a lean A/F mixture). Excessive voltage is determined by comparing the HO2S signal voltage to a maximum calibratable threshold voltage. FordP1131 Ford DTC P1131 Make: Ford Code: P1131 Definition: Lack of HO2S-11 Switching, HO2S Signal Low Input Description: DTC P0300-P0310 not set, engine started, engine running in closed loop, and the PCM detected the HO2S-11 was not switching (i.

Once the HO2S Monitor is enabled, the upstream HO2S signal voltage amplitude and response frequency are checked.

The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function.

Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. Lean of stoichiometric (air/fuel ratio of approximately 14.7:1 for gasoline engines), the HO2S will generate a voltage between zero and 0.45 volt.

The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt.

The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled. Input is required from the Engine Coolant Temperature ( ECT) or Cylinder Head Temperature (CHT), Inlet Air Temperature (IAT), Mass Air Flow ( MAF), Throttle Position (TP) and Crankshaft Position ( CKP) sensors to activate the HO2S Monitor. Downstream HO2S sensors used for Catalyst Monitor are also monitored for proper output voltage. In these instances, P1131 will set when the voltage being returned by the sensor is no longer switching above and below approximately.

Under specific conditions, the fuel control or upstream HO2S sensors are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Code P1131 is a manufacturer’s specific code and as such lets you know that diagnosing this condition may be different between manufacturer’s vehicles.
