Check Engine Light & Diagnostics
Proper diagnosis of check engine lights and drivability faults, by technicians with over forty years of diagnostic experience.
What The Job Involves
A code reader tells you which circuit reported a fault. It does not tell you which part failed — and replacing parts based on the code alone is how people end up paying three times for one repair.
Engine diagnostics means reading the data the vehicle’s computer holds, testing the circuits and components involved, and confirming the fault before anything is replaced. Our technicians have over forty years of diagnostic experience between them, which is why we fix these right the first time.
A check engine light will also fail a Pennsylvania emissions test, so it is worth dealing with before your inspection is due.
