Engine Diagnostics & Check Engine Light in Windsor
A check engine light is a symptom, not an answer. Helonk Autoshop reads the codes, tests the live data, and road-tests your vehicle to find the real cause: sensors, ignition, fuel delivery, emissions, or something simpler.
You get the finding explained in plain English and a written estimate before any repair begins. We fix the problem and re-check the system so the light stays off, not just cleared.

- OBD-II computer scan and code reading
- Live sensor data and electrical testing

FAQs
Can you just clear my check engine light?
We can, but clearing a code without fixing the cause hides the problem and it will come back. Our job is to find what is actually wrong and tell you honestly what it takes to fix it.
How long does a diagnostic take?
Most diagnostics are completed the same day. Intermittent faults can take longer, and we will tell you upfront what to expect.
How much does a diagnostic cost?
Diagnostic pricing varies by vehicle and system. Call (519) 796-8996 and we will give you a straight answer before you come in.
