On a high-mileage Lawrence vehicle, a check engine light is often several small faults at once, and the job is working out which one is actually causing the problem. Reading the code is the start of that, not the answer.
What Diagnostics & Check Engine Covers
- OBD-II and manufacturer-level scan tools
- Drivability and intermittent fault diagnosis
- Electrical, sensor, and emissions troubleshooting
- Detailed report of findings and recommended repairs
- EV diagnostics including Rivian
Older engines collect vacuum leaks, tired sensors and exhaust leaks over time, and each can throw codes that point at something else. A cracked intake hose can set a lean code that looks like a fuel problem. We test the circuit and watch live data before naming a part.
For working vehicles, a warning light also raises a practical question: can it keep running today or not? We'll tell you that plainly, along with what the repair involves.

Lawrence Questions About Diagnostics & Check Engine
- My check engine light came on in my work van. Can I keep driving it?
- A steady light usually means it can be driven carefully until it's checked. A flashing light means an active misfire, and the van should be parked to avoid damaging the catalytic converter.
- Why replace a part only to have the light come back?
- Because the code named a symptom, not the cause. Testing the circuit and reading live data first is how we avoid replacing parts that were working.
