Having the 2016 Dodge Dart check engine light on can be alarming. Fortunately, there are steps you can take to address the issue. Below are some common causes that might trigger the light.
Common Causes of Check Engine Light Issues
Excessive Oil Consumption
Several Dodge Dart owners have reported excessive oil consumption in their vehicles, often related to specific piston rings. These rings are crucial for sealing oil within the engine and maintaining the gap between the piston and the cylinder wall. If these rings fail, oil can leak into the combustion chamber, leading to unpleasant odors and blue exhaust smoke.
Monitoring your car’s oil consumption is essential. Avoid using excessive oil as it can damage engine components. Always opt for high-quality oil to extend the life of your engine.
Faulty Oxygen Sensor
A faulty oxygen sensor can significantly affect the engine’s performance, leading to reduced power and fuel efficiency. It may also harm spark plugs and catalytic converters. Symptoms of a malfunctioning sensor include rough engine running, poor fuel economy, and high emissions. If you suspect an issue, have your car professionally diagnosed.
Oxygen sensors are essential for emissions control. They measure the oxygen levels in the exhaust and provide data to the vehicle’s computer, which adjusts the air-fuel mix accordingly. A malfunctioning sensor sends incorrect data, leading to inefficiencies.
Gas Cap Issues
A functional gas cap is essential for preventing fuel from leaking and evaporating. A faulty gas cap can cause the check engine light to turn on due to leaks. Common issues include a loose or cracked gas cap. If you suspect a leak, replacing the cap is straightforward and can save you time and money.
Vacuum System Issues
Recent recalls of Chrysler vehicles, including the Dodge Dart, have highlighted issues with the vacuum system that might not be immediately apparent. These issues could increase the risk of accidents. Problems may include a brake pedal that fails to reach the floor when pressed, unusual brake noises, and potential engine stalls in cold weather. According to Chrysler Group, contamination of the brake booster with oil may degrade the booster’s diaphragm, leading to a loss of brake-assist function.
Ignition Timing Issues
Incorrect ignition timing can lead to engine misfire, with common symptoms including hesitation, poor fuel economy, and a rough idle. Misfiring might also cause the car to backfire, resembling a shotgun blast. The ignition system, comprising spark plugs, wires, and ignition coils, is vital for your vehicle’s operation. Any issues with these components should be addressed promptly.
Brake Calipers and Parking Brake Malfunctions
If you are experiencing issues with your brakes, consider having your car checked by a professional mechanic to diagnose and resolve any problems efficiently. Start by checking your brake fluid level. A low level could indicate a malfunctioning brake system, potentially caused by a faulty hydraulic system. Also, look for any leaks. A malfunctioning parking brake could pose a risk, particularly if it fails to release, potentially causing the vehicle to roll unexpectedly.
Resetting The Check Engine Light
Whether you drive your own car or a friend’s Dodge Dart, you might need to reset the check engine light at some point. This light can indicate significant vehicle issues that should be addressed promptly. Performance issues and a malfunctioning gas cap can also trigger the light. If it comes on after refueling, check the gas cap for looseness. If it remains on, replacement may be necessary.
