On Board Diagnostics for Bentonville Motorists
October 17, 2021
Some Bentonville vehicle owners wonder why Mr. Lube and other Bentonville auto repair shops charge a fee for vehicle diagnostics.
Receiving a diagnostic charge at Mr. Lube for a tricky automotive problem shouldn't be a surprise. In the Bentonville area, automotive diagnostics can cover quite a range. If you hear a noise in your vehicle brakes when you slow down in rush-hour traffic on a busy Arkansas road, you pull off at the next off-ramp and take a quick visual check. That is usually enough to know what needs to be done. If you're having an intermittent problem with your vehicle engine, however, a Mr. Lube diagnosis may be much more involved.
Much of the Bentonville driver's confusion comes when the problem involves the Check Engine light. The Check Engine light comes on when the engine management computer has sensed a problem.
There's a common misconception among Arkansas drivers that the trouble code tells the Mr. Lube technician exactly what's wrong. They wonder why there is a diagnostic charge because the scanner quickly gave the diagnosis.
In reality, it is not that easy and straightforward. The computer monitors many sensors throughout the vehicle. When one of these sensors has a reading that's out of parameters, the computer will record a trouble code and turn on the Check Engine light.
The vehicle computer's trouble code just tells the Mr. Lube technician what engine parameter is out of range, not what's causing it. The technician needs to determine the underlying problem that's causing the malfunction.
There are many problems that could cause a troublesome sensor reading for Mr. Lube customers. The service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.
Bentonville service centers subscribe to databases that document possible causes for all the possible trouble codes. The databases outline procedures for confirming a diagnosis and provide the documented repair. These databases are specific to each vehicle and engine combination.
Some diagnoses are quick and easy. Others are more involved, time-consuming and difficult. Of course Mr. Lube wants to figure out what's wrong with your vehicle and get you back on the road as quickly as possible.
