It’s the bane of many motorists, that little yellow symbol, but what does it mean? A check engine light can indicate anything from a loose gas cap to a major engine malfunction, so it can be difficult to know at a glance just what it means. Thankfully the experts here at Go Dodge Red Deer have collected a number of the most common check engine light codes so you can know what’s wrong with your vehicle in a flash!
How to Read a Code
First things first, how to translate that annoying flashing light into a readable code. You’ll need a OBD-II reader, which is a miniature computer that scans your vehicle and interprets the check engine light. These can be bought for a small fee, and allow you to quickly read your engine codes. Of course, you can also Book an Appointment with us to have our expert technicians scan your vehicle!
List of Codes
Here is a list of the most common check engine light codes and what they mean:
- P0130 – P0177– These codes have to do with your O2 sensor. This sensor measures the oxygen in the exhaust, which then tells your car’s computer whether it needs to inject more or less fuel.
- P0440– This well known code is for General Evaporative System Failure often caused by a loose fuel cap. The first thing to do is tighten your fuel cap. A loose fitting fuel cap can cause gas to evaporate over time.
- P0171 – P0174– Fuel System Lean/Rich. This code will be triggered when the catalyst monitor finds a drop in catalytic converter efficiency. This is one code that can mean an expensive fix; it can also mean that there may be other underlying problems with your vehicle.
- P0300 – P0312– Multiple Cylinder Misfire. These 12 codes have to do with your ignition fuel and electrical system. The number that follows the P030 code represents the number of cylinders that may be misfiring. A bad ignition coil may not be the only cause of the misfiring and it could be an easy fix such as a bad spark plug, or it could be something more serious.
- P0440/P0443/P0452/P0455/P0456- These codes are not just for the fuel cap; it is also the most common code you will find when it comes to your EVAP or Evaporative Emission Control System and faulty hoses.
- P0401– This code relates to the EGR or Exhaust System Performance in your car. If this code is scanned, it is likely that you have a bad valve. A problem with your car’s EGR valve could cause your car to idle roughly and your engine to be choppy.
- P0217– This code will light up when your engine is overheating. This light should come on prior to any damage being done to your engine. Your car may also trigger this code if you are low on coolant.
- P0463– This check engine code can be triggered by the fuel level sensor, which is found in your car’s fuel tank. If a problem occurs in your gas tank, it will trigger this code.
- P0115– Triggered by the Engine oil temperature being too high.
