Is Your Check Engine Light On?
The first thing to remember is that when the check engine light stays on, its time for some car maintenance. Inspecting your car sooner rather than later can help you to avoid costly repair problems down the road. The service engine light is connected to the electronic control module (ECM) of the vehicle. The ECM essentially acts as the electrical brain. It your car’s onboard computer. Currently there are many sensors throughout the vehicle that feed back information to the onboard computer and monitor their performance. If the onboard computer recognizes that a specific thing is not up to factory standards, then it will turn the check engine light on. The most important thing to remember is not to drive with your check engine light on. It is not advisable to simply ignore the check engine light until your car starts exhibiting performance problems, like poor gas mileage, stalling, surging, stumbling, and breaking down, and/or failing your smog test.

There are many reasons for the engine check light to become active.Here are a few common ones
Mass Airflow Sensor
You car’s oxygen sensor helps monitor how much fuel is being burned by measuring the unburned oxygen from the exhaust. If the sensor fails, it won’t provide the right data to the computer and will cause a reduction in gas mileage, and increase emissions. Most cars have between two and four oxygen sensors. They can get covered in oil and ash which reduces their ability to change the fuel and oxygen mixture. Not replacing a broken oxygen sensor can lead to the failure and breaking of your catalytic converter, which can be very expensive. When you bring your car to Pacific Automotive, we can scan your car and the code from the scanner will tell us which of the oxygen sensors need replacing.
