The automobile fault code P1132 indicates a problem with the upstream oxygen sensor in Bank 1. This can cause the engine light to turn on or the service engine soon warning light to illuminate. The possible causes for this fault code include a faulty oxygen sensor, high or low fuel pressure, a dirty or defective MAF sensor, a vacuum leak on the engine, a leaking fuel injector or fuel pressure regulator, or a faulty Powertrain Control Module (PCM).

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded connector pins. The repair time for this issue is estimated to be around 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for this type of repair.

The P1132 fault code indicates a lack of switching in the upstream heated oxygen sensor (HO2S) on the rich bank of the engine.

The HO2S is responsible for monitoring the oxygen content in the exhaust flow and generating a voltage signal based on the airfuel ratio. To activate the HO2S monitor, input is required from various sensors such as the engine coolant temperature, inlet air temperature, mass air flow, throttle position, and crankshaft position.

The fuel system monitor and misfire detection monitor must also have completed successfully before the HO2S monitor is enabled. Once enabled, the HO2S monitor evaluates both the upstream (fuel control) and downstream (catalyst monitor) HO2S for proper function. It checks the voltage amplitude and response frequency of the upstream HO2S to ensure it is switching correctly.

Excessive voltage is determined by comparing the signal voltage to a maximum threshold. In the case of a P1132 code, the lack of switching in the upstream HO2S on the rich bank indicates a potential issue with the sensor or the fuel mixture. This fault code triggers the activation of the malfunction indicator lamp (MIL) after being detected on two consecutive OBD II drive cycles.

What are the possible causes of the automobile fault code P1132?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1132 could be the culprit. This code is often caused by a faulty upstream oxygen sensor in bank 1, high or low fuel pressure, a dirty or defective MAF sensor, a vacuum leak on the engine, a leaking fuel injector or fuel pressure regulator, or even a faulty Powertrain Control Module (PCM). To fix the issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, inspect for any damage, and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the P1132 fault code?

If you’re dealing with the P1132 fault code and your engine light is on, there are a few things you can do to fix it. Start by checking the possible causes, which include a faulty upstream oxygen sensor, high or low fuel pressure, a dirty or defective MAF sensor, a vacuum leak on the engine, a leaking fuel injector or fuel pressure regulator, or a faulty Powertrain Control Module (PCM). To visually inspect the issue, take a look at the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What should I look for when checking for damaged components and connector pins to resolve the P1132 fault code?

When resolving the P1132 fault code, start by checking for damaged components and connector pins. Visually inspect the related wiring harness and connectors, looking for any broken, bent, pushed out, or corroded pins. This can help identify any issues that may be causing the fault code. Additionally, be sure to check the “Possible Causes” listed, such as a faulty upstream oxygen sensor, high or low fuel pressure, a dirty or defective MAF sensor, a vacuum leak on the engine, a leaking fuel injector or fuel pressure regulator, or a faulty Powertrain Control Module (PCM).

p1132 error fault code explained

If you’re seeing the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a faulty Upstream Oxygen Sensor Bank 1, high or low fuel pressure, a dirty or defective MAF sensor, a vacuum leak on the engine, a leaking fuel injector or fuel pressure regulator, or a faulty Powertrain Control Module (PCM). To fix this, check the possible causes mentioned above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded pins on the connectors.
