These sensors detect the levels of oxygen present in the exhaust, which is a primary component in maintaining the optimal air-fuel ratio. It plays a vital role in monitoring the levels of oxygen present in the exhaust gases produced during the combustion process. Conversely, if the sensor detects that there is not enough oxygen in the exhaust gases, it indicates that the engine is running rich , and the ECM should reduce the amount of fuel being delivered. By continuously monitoring the oxygen levels in your exhaust gases, the sensor ensures that the air-fuel mixture is maintained within a narrow range to optimize engine performance, reduce harmful emissions, and maintain good fuel economy. We cover codes and what to do further down the page. Issues like rough idling, misfiring, and engine hesitation can occur, causing your FJ Cruiser to feel underpowered.
