On Board Diagnostics For Pleasanton Motorists

So receiving a diagnostic charge at Precision Auto Repair for a tricky automotive problem shouldn’t be a surprise. In the Pleasanton area, automotive diagnostics can cover quite a range. If you hear a noise in your Honda, Acura, Toyota or Lexus brakes when you slow down in rush-hour traffic on a busy California 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 Honda, Acura, Toyota or Lexus engine, Precision Auto Repair diagnosis may be much more involved.

Much of the Pleasanton 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 Livermore, San Ramon , and Dublin drivers that the trouble code tells the Precision Auto Repair 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 Honda, Acura, Toyota or Lexus computer's trouble code just tells the Precision Auto Repair 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 Precision Auto Repair Pleasanton customers. The Precision Auto Repair technician makes a list of the most likely causes and begins tracking down the source of the problem.

Pleasanton 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 Precision Auto Repair wants to figure out what’s wrong with your Honda, Acura, Toyota or Lexus and get you back on the road as quickly as possible.
