P1132 - FAULT CODE - OBD2

    Description of DTC code P1132 Generic

    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.

    Symptoms of fault code P1132 Generic

    Causes of OBD2 P1132 Generic

    Reasons for setting the P1132 OBDII fault code:

    • The fuel pressure may not meet the required levels.
    • There may be vacuum leaks from the engine.
    • The Oxygen Sensor on bank 1 may be faulty.
    • The fuel pressure regulator or a fuel injector may be damaged.
    • There may be contamination in the Mass Air Flow Sensor.

    Possible solutions of the DTC code P1132 Generic

    To troubleshoot the P1132 OBD2 DTC on your Ford, consider the following steps:

    • Start the diagnosis by consulting the Technical Service Bulletins. Besides, check with a scanner if other fault codes are stored, taking into account those codes that relate to the exhaust system first.
    • Check all the connectors, wiring, and other electrical components in the Oxygen Sensor circuit for bank 1 for deficiencies. Repair or replace if any of these are damaged.
    • Check that the fuel pressure is within the levels required for good performance. If you find out-of-range pressure, check the condition of the pressure regulator as well as the injectors. Make any necessary adjustments.
    • Check the intake manifold connections and hoses for damage that could cause vacuum leakage into the engine. If such damage is found, make any necessary corrections.
    • If after performing the above diagnostics and corrections you still get the code P1132, you need to check the integrity of the Oxygen Sensor. If you determine that it is bad, replace it.
