There are many reasons why your import’s check engine light will turn on. Uptown Imports is going to discuss check engine light causes below. Don’t worry. We can find out why the check engine light has been illuminated on your dashboard and fix the problem.
Catalytic Converter
The catalytic converter is part of your import’s exhaust system. It treats your vehicle’s emissions so they are safe to be released out of the tailpipe. A check engine light will turn on if the catalytic converter is clogged or malfunctioning.
EVAP Control System
The EVAP control system makes certain that you don’t end up with any diesel fuel or gasoline evaporation out of your automobile. If the system is faulty, the check engine light will turn on. In fact, it will even turn on if your gas cap is too loose.
Engine Control Unit
The engine control unit is the main computer chip. This chip communicates with the system sensors throughout your import. The ECU generally does not go bad, but there have been instances where the chip malfunctions and the check engine light turns on.
MAF Sensor
Your import might also have a mass airflow sensor to detect the incoming air. If the MAF sensor gets dirty or goes bad, the check engine light will turn on due to a system sensor error code. Generally, a faulty MAF sensor also affects your engine’s performance.
O2 Sensor
The same is true when it comes to the oxygen sensor. This sensor keeps track of the exhaust oxygen levels. Plan to have the O2 sensor changed about every 100,000 miles. This is the general lifespan of this exhaust system part.
Transmission
Your check engine light might also come on if your import is experiencing transmission problems. The transmission sensors will send error codes to the engine control unit to alert it of trouble. It will turn on the check engine light because the transmission does not have a light.
Spark Plugs/Wires
Finally, another common reason why the check engine light turns on his worn spark plugs and/or wires. Alongside the dashboard warning, your engine may also misfire and stall. Replacing the spark plugs will resolve the problem and turn off the check engine light.
