Sep 25, 2023 · Faulty Oxygen (O2) Sensor. The first cause can be a faulty O2 sensor. The O2 sensor measures the oxygen levels in the exhaust system and sends a signal to the vehicle’s onboard computer. If the sensor fails, the computer may not receive accurate readings, causing the engine management light to come on. A faulty O2 sensor can also cause poor Dec 27, 2021 · The O2 sensor in Corsa monitors the level of oxygen in the exhaust gasses that exit the engine and reports the data to the control unit which continuously adjusts the air-to-fuel ratio in the engine. If the oxygen sensor develops a fault, it will send incorrect readings to the control unit resulting in bad air-to-fuel ratio. Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.

Dec 29, 2018 · Oxygen Sensor– The P0172 code is thrown when the B1S1 O2 sensor does not register the right amount of oxygen in the exhaust. The computer will still adjust the air/fuel mixture to compensate. A bad O2 sensor will show a lean mixture more often, though. Mass Air Flow Sensor– Your Corsa’s mass air flow sensor calculates the volume of air Sep 15, 2023 · It’s triggered when the PCM detects a fault in the heater circuit of the downstream oxygen sensor in Bank 2. Some possible causes include damaged wiring, a faulty oxygen sensor, and a blown fuse. Two symptoms to look out for are an illuminated check engine light and decreased fuel efficiency. .
