Auto Repair in Mint Hill – What is OBDII?

If you’ve had an emissions inspection done on your vehicle, or have ever had a check engine light come on, you’ve most likley heard the term “OBDII” before. But do you know what it means?

OBDII is an acronym for On-Board Diagnostics II. OBDII is a car’s self-diagnositc tool, it can perform basic diagnostics on itself and can give a broad idea on what is or isnt causing a problem. If you own a car that is model year 1996 or newer, you have OBDII. Though some vehicles from madel year 1995 have OBDII, it was not legally required.

What Can OBDII Do?

OBDII’s most common use is as a self-diagnostic tool. For example, whenever your check engine light comes on, OBDII also generates a code which shows why the light is on. For example, if you have a misfire, your check engine light would come on and OBDII would produce a code like P0300.

Are there Downsides to OBDII?

While in some areas OBDII can be very speific, in others it can be broad. For example, code P0300 means “Random or Multiple Misfires.” While this information is useful, it doesnt clarify why those random misfired happened, it only shows that misfires happened. OBDII is best used as a tool to “point you in the right direction” as compared to a definite diagnostic.

Why is OBDII Important?

While OBDII helps diagnose issues, like a misfire, OBDII also helps keep our air cleaner by monitoring emissions systems. OBDII is also what makes State Inspections possible. OBDII is also responsible for speeding up diagnostic times on engine related repairs.

Auto Repair Mint Hill; Cooling System Maintenance

Auto Repair Mint Hill; Cooling System Maintenance.  I bet this time of year you are not thinking of your  Car’s Cooling System.  The truth is, this is a critical time of year for a car’s cooling system because we experience a change in temperatures that may uncover an issue that went unnoticed when the temps were warmer.  Cooling system failure is the number 1 cause of roadside auto failure.  Your cooling system consists of not just your radiator but the hoses and belts that operate them along with the coolant or antifreeze in your system.

If your car’s antifreeze is low the fluid in your engine can freeze and crack your engine block and cause a whole host of issues. But it does not stop there, look for cracks on the surface of drive belts.  These belts can be connected to your water pump, fan etc.  they need to be in good working order.  Belts  that are worn can make a lot of noise, especially in the morning.  If you hear noise coming from your engine in the morning, this may be something that needs further investigation.  Hoses are connected to your radiator and circulate antifreeze to vital components of your car.  Make sure these are not cracked or spongy, many times hoses fail from the inside out so it can be difficult to detect if you do not know what to look for.

Additionally, a bad thermostat can result in low heater output, overheating, poor fuel economy, knocking and pinging during acceleration, high idle speed or an electric cooling fan that runs continuously.  All of these things can impact your car’s performance when the mercury falls.

Performing routine car maintenance is meant to prolong the life of your vehicle and hopefully avoid major problems that can leave you stuck on the side of the road.  Setting up a schedule with a reputable auto repair facility can take the headache out of remembering when to do what and keep you on track.
