P1132 FORD - LACK OF UPSTREAM HEATED OXYGEN SENSOR SWITCH SENSOR INDICATES RICH BANK 1
A strategy called O2 Sensor monitoring verifies the right performance of the O2 Sensors. When it is necessary, the fuel supply is adjusted by regulating the output voltage of the Oxygen Sensors to make the output voltage and response rate may be within the appropriate levels.
The inputs of the intake air temperature activate the HO2S monitor, coolant temperature (ECT), mass airflow (MAF), crankshaft position, and throttle position. Also, ignition and fuel system misfire detection monitoring tests need to be completed. With this data and being the HO2S activated, some checks are performed about how wide the upstream O2 Sensor signal voltage is, as well as the response time of the upstream O2 Sensor.
The P1132 OBD2 diagnostic code is a specific code that applies only to the Ford manufacturer. When this code is set, it is because the fuel control system fails to determine switching within a calibrated time.
Reasons for setting the P1132 OBDII fault code:
