My Check Engine Light is on. What Happened?

Don't wait to find out! An early diagnosis of an engine problem could save you on repairs! *Check Engine Light Diagnosis $145.*

The Check Engine Light is a catch all light that says something is wrong with your car and you need to have your car's computer diagnostically tested. A detailed diagnostic code will tell what is wrong with your engine. The light itself doesn't indicate any one particular problem, but the test will narrow it down so our Certified Technicians can focus on the system that is triggering the light. At Larry H. Miller Chrysler Dodge Jeep Ram 104th we specialize in the makes and models we sell. Visit our state of the art Service Center near Denver, on 104th. Check out our monthly service coupons.

What makes a warning light come on?

Today's vehicles have complex systems, and on board computers monitor and store information about the performance of the systems. A warning light comes on because the computer has sensed a signal from one of the systems that has gone outside of its normal range. The computer sends a signal turning the dashboard warning light to let you know something is wrong.

How do we diagnosis the system causing the light?

At Larry H. Miller Chrysler Dodge Jeep Ram 104th, we have the tools, training and technology to handle diagnostic issues, such as a Check Engine light. The car is hooked up to a service department computer which delivers a code.The On Board Diagnostic (OBD) Code can be confusing, just because you have a diagnostic code for a certain system on the car, it does not mean the part needs to be replaced. It means a particular System has a problem and needs further diagnose to determine why the computer is sending the code. All parts of the system must be checked and tested to see if the problem is with the sensor, wiring, computer or even with another, related sensor or system.
