A malfunctioning oxygen sensor can cause a variety of issues in a car, and can also trigger the 2003 Dodge Dakota check engine light to turn on. The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust gases, and sending a signal to the engine control module (ECM) to adjust the air-fuel ratio.

When the oxygen sensor is not working properly, the ECM may not be able to adjust the air-fuel ratio correctly. This can cause the engine to run lean, meaning the air-fuel ratio is too high, which can lead to poor engine performance, such as hesitation, stalling, and decreased power. It also increases the risk of damage to the catalytic converter, which is an important component of the emission control system. Additionally, a malfunctioning oxygen sensor can also cause increased fuel consumption and higher emissions.

2003 Dodge Dakota check engine light will be turned on when the ECM detect a malfunctioning in the Oxygen sensor, this will be also stored as a diagnostic trouble code (DTC) in the ECM’s memory. A qualified mechanic can use a scan tool to retrieve the DTC and determine the specific cause of the problem. The oxygen sensor is usually replaced when the check engine light is on, and the code is pointing to a malfunctioning oxygen sensor.

It is important to address a malfunctioning oxygen sensor as soon as possible to prevent further damage to the vehicle and to ensure that it’s running efficiently, minimizing emissions and fuel consumption.
