Common Causes Of Check Engine Light
The 2016 Jeep Cherokee’s engine light may illuminate due to various issues such as a faulty head gasket, dirty mass airflow sensor, malfunctioning emissions control part, fuel injection system problem, damaged oxygen sensor, or defective spark plugs. Prompt diagnosis and service are crucial when the engine light is flashing.
Schedule a comprehensive check-up with a trusted auto repair shop to address the underlying issues.
Faulty Head Gasket
If you notice your Jeep Cherokee’s check engine light is on, one of the common causes could be a faulty head gasket. The head gasket plays a crucial role in sealing the combustion chamber and preventing any leaks that could affect the engine’s performance. When the head gasket fails, it can lead to various issues, including engine misfires, overheating, loss of coolant, and even damage to the engine block. It is essential to address this issue promptly to avoid further damage to your vehicle.
Dirty Mass Airflow Sensor
Another common cause of the check engine light in a Jeep Cherokee is a dirty mass airflow sensor (MAF sensor). The MAF sensor measures the amount of air entering the engine, which helps the engine control unit (ECU) regulate fuel injection and ignition timing. When the MAF sensor becomes dirty, it can lead to inaccurate readings and disrupt the engine’s performance. Cleaning or replacing the MAF sensor can resolve this issue and ensure your engine runs smoothly.
Faulty Emissions Control Part
Your Jeep Cherokee’s check engine light may also indicate a problem with a faulty emissions control part. The emissions control system is responsible for reducing harmful emissions from the exhaust gases. If a component such as the catalytic converter, oxygen sensor, or EGR valve malfunctions, it can trigger the check engine light. Getting the faulty emissions control part repaired or replaced is crucial not only for the proper functioning of your vehicle but also for reducing its environmental impact.
Malfunction With Fuel Injection System
A malfunction in the fuel injection system can also be a common cause of the check engine light in a Jeep Cherokee. The fuel injection system is responsible for delivering the right amount of fuel to each cylinder for combustion. Issues with fuel injectors, fuel pressure regulators, or the fuel pump can disrupt this process, leading to poor engine performance and increased emissions. It is crucial to have the fuel injection system checked and repaired by a qualified technician.
Defective Spark Plugs
The check engine light in your Jeep Cherokee may also illuminate due to defective spark plugs. Spark plugs play a vital role in igniting the fuel-air mixture in the combustion chamber. If the spark plugs are worn out, fouled, or not functioning correctly, it can result in engine misfires, reduced fuel efficiency, and overall poor performance. Replacing the spark plugs with new ones that meet the manufacturer’s specifications will resolve this issue and ensure optimal engine operation.
Malfunctioning Oxygen Sensor
A malfunctioning oxygen sensor can trigger the check engine light in your Jeep Cherokee. The oxygen sensor measures the amount of oxygen in the exhaust gases and provides feedback to the engine control unit for adjusting the fuel mixture. When the oxygen sensor fails or becomes faulty, it can lead to inaccurate readings and affect the engine’s performance. Replacing the malfunctioning oxygen sensor will restore the proper functioning of the engine and turn off the check engine light.
