Check engine light diagnostics

A check engine light can mean a loose gas cap or a misfire cooking your catalytic converter. We scan the code, test what it points to, and tell you which one you have.

A code is a starting point, and parts-cannon repairs get expensive. We test the circuit or component behind the code, explain the fault in plain terms, and tell you whether the car is safe to drive while you decide. If the fix can wait, we say so.

What it costs

Diagnosis is billed as its own step, so you can take the answer and decide what to do next. Most people have us fix it the same visit.
