Engine Diagnostics

A check engine light can mean anything from a loose gas cap to a serious engine issue.

About This Service

A check engine light can mean anything from a loose gas cap to a serious engine issue. At Broadway Motors, we use professional diagnostic equipment to read the codes, identify the root cause, and explain your options clearly — no jargon, no guesswork.

What's Included

OBD-II Code Reading

We pull the diagnostic trouble codes and interpret what they actually mean for your specific vehicle.

Root Cause Diagnosis

Codes point to a system, not always the exact part. We trace the issue to the actual problem so you don't waste money replacing the wrong thing.

Clear Explanation

We'll explain what's wrong in plain English, what needs fixing now, and what can wait. No pressure.

Frequently Asked Questions

Is it safe to drive with the check engine light on?

A steady check engine light usually means something needs attention soon but isn't an emergency. A flashing check engine light means stop driving and get it looked at immediately — it can indicate a misfire that damages your catalytic converter.

How long does a diagnostic take?

Code reading takes minutes. Full diagnosis of the underlying issue typically takes 30–60 minutes depending on the complexity.
