P1152 Fault Code: Understanding The Description And Troubleshooting Tips
The P1152 fault code indicates a lack of upstream heated oxygen sensor (HO2S) switch sensor activity, specifically indicating a rich bank.
The HO2S monitors the oxygen content in the exhaust flow and outputs a voltage between zero and 1.0 volt.
When the airfuel ratio is lean, the HO2S generates a voltage between zero and 0.45 volt. When the airfuel ratio is rich, the HO2S generates a voltage between 0.45 and 1.0 volt. The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function.
Once the HO2S Monitor is enabled, it checks the upstream HO2S signal voltage amplitude and response frequency. If the voltage exceeds a maximum threshold, it indicates an excessive voltage.
The routine also evaluates the sensor’s ability to switch or its response rate. In addition, the fault code can be triggered by a fault in the HO2S heater circuit. This is determined by turning the heater on and off and observing any corresponding changes in the OSM (Onboard System Monitor).
The current flowing through the heater circuit is also measured. If a fault is detected on two consecutive OBD II drive cycles, the Malfunction Indicator Lamp (MIL) is activated.
This indicates the need for attention and potential repair to address the lack of upstream HO2S switch sensor activity indicating a rich bank.
