Engine Diagnostics & Check Engine Light
Advanced computer scanning, live sensor data analysis, EVAP smoke testing, and fuel trim calibration by ASE-certified mechanics.
Service Overview
A Check Engine Light can mean anything from a loose gas cap to a failing catalytic converter or dangerous cylinder misfire. At Rinaldi Auto Service, we don't just clear trouble codes—we diagnose the root cause with digital live-data scanners.
What Our Service Includes
OBD-II Code Scanning & Live Data Stream
We analyze fuel trim, oxygen sensor voltages, ignition timing, and mass air flow readings in real-time to locate the exact malfunctioning sensor or component.
EVAP Vacuum & Smoke Leak Testing
Evaporative emissions leaks trigger persistent check engine lights. Our smoke machines pinpoint micro-leaks in vapor lines, canister purge valves, and seals.
Common Warning Signs & Symptoms
If you notice any of the following, schedule an inspection promptly:
- Solid or flashing amber Check Engine Light on dashboard
- Engine runs rough, stumbles at stoplights, or hesitates on acceleration
- Sudden, noticeable drop in vehicle MPG
- Failed Pennsylvania emissions or OBD state inspection
Frequently Asked Questions
Can I drive if my Check Engine Light is blinking?
DO NOT drive with a flashing check engine light. A flashing light signifies active cylinder misfire that is dumping raw fuel into the catalytic converter, risking fire and catastrophic damage.
