The 5 Most Common Reasons For A check Engine Light

The 5 Most Common Reasons For A Check Engine Light In Johnson City, TN

The weather in Johnson City can be unpredictable. One day it's sunny and warm, and the next day you're driving in a snowstorm. But no matter the weather outside, if your car's check engine light is on, you should get it checked out as soon as possible.


At Ponder Auto Repair in Johnson City, TN, we know that a check engine light can be stressful. That's why it helps to know the five most common reasons why this warning light appears so you can better understand what might be causing the issue. Let's take a look at those five reasons now.

Loose or Faulty Gas Cap

A loosening gas cap is one of the most common reasons a check engine light comes on. It's an easy fix: inspect your gas cap and see if it needs to be tightened or replaced. If you need to replace it, get one that fits your vehicle properly from Ponder Auto Repair in Johnson City, TN.

Faulty Oxygen Sensor

Your car's oxygen sensor is responsible for monitoring the exhaust gases that leave your engine and ensuring they are at an optimal level for combustion efficiency. If this sensor malfunctions, your car won't run efficiently and will cause your check engine light to come on. If this happens, bring your vehicle into Ponder Auto Repair right away so our technicians can look at it and get it fixed quickly, so you don't have to worry about any further damage caused by faulty oxygen sensors.

Mass Air Flow Sensor Issues

Your mass airflow (MAF) sensor measures the amount of air entering your engine; if this sensor fails or has issues, your car won't run as efficiently as it should, which will cause the check engine light to come on. Fortunately, this is usually an easy fix with some basic maintenance from Ponder Auto Repair in Johnson City, TN.

Spark Plug Issues

Spark plugs ignite the fuel inside the cylinders of an internal combustion engine which causes power production from each cylinder; if these spark plugs fail due to age or wear and tear, then they won't ignite fuel correctly, which will cause a decrease in performance and increase in emissions leading to that pesky check engine light coming on! Bring your vehicle into Ponder Auto Repair so our technicians can inspect them for any signs of wear and tear or replacement needs before they become a bigger problem down the road!

Catalyst System Failure

The catalyst system helps reduce harmful exhaust emissions produced by vehicles; if these systems fail due to age or wear and tear, then they won't be able to do their job correctly, which results in increased emissions leading to that dreaded check engine light coming on! Make sure you bring your vehicle into Ponder Auto Repair for regular inspections so we can spot any potential problems before they become bigger issues down the road!
