# Check Engine & Diagnostics

> Computerized diagnostics that find the real cause of warning lights, noises, and performance issues.

A check engine light can mean anything from a loose gas cap to a failing sensor. Instead of guessing, we use professional diagnostic equipment to read your vehicle's computer and pinpoint the actual cause.

## When to come in

- Your check engine, ABS, or other warning light is on
- The engine is running rough, stalling, or hard to start
- You've noticed a drop in fuel economy or power
- There's an unusual noise, smell, or vibration

## Our diagnostic process

1. We connect to your vehicle's onboard computer and read the trouble codes.
2. We test the related components rather than just replacing parts.
3. We explain what we found in plain language and give you a written estimate.
4. You approve the work before we begin.

Accurate diagnosis saves you money by fixing the real problem the first time. [Schedule a diagnostic](/contact) today.
