On Board Diagnostics For Wichita Motorists

So receiving a diagnostic charge at Yost Auto Service for a tricky automotive problem shouldn’t be a surprise. In the Wichita area, automotive diagnostics can cover quite a range. If you hear a noise in your minivan brakes when you slow down in rush-hour traffic on a busy Kansas expressway, you pull off 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 minivan engine, Yost Auto Service diagnosis may be much more involved.

Much of the Wichita public’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 Andover, Goddard, and Park City drivers that the trouble code tells the Yost Auto Service technician exactly what’s wrong. Why then is there a diagnostic charge, the scanner just gave the diagnosis?

Reality is more involved than that. 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 minivan computer’s trouble code just tells the Yost Auto Service 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 symptom.

There are many problems that could cause a troublesome sensor reading for Yost Auto Service Wichita customers. The Yost Auto Service technician makes a list of the most likely causes and begins tracking down the source of the problem.

Wichita service centers subscribe to databases that document possible causes for a given trouble code. They outline procedures for confirming a diagnosis and provide the documented fix. These databases are specific to each vehicle and engine combination.

Some diagnoses are quick and easy. Others are more involved and difficult. Of course Yost Auto Service wants to figure out what’s wrong with your minivan and get you back on the road as quickly as possible.
