Diagnostics first • no guessing
Check Engine Light Diagnostics in Mississauga
A check engine light does not automatically mean one specific part has failed. It means the vehicle has stored a fault that needs proper testing before parts are replaced.
Diagnostics start at 1 hour labour: $145. We test first, explain the findings, then quote repairs clearly before work continues.
Why diagnostics-first matters
A code is not a diagnosis
Codes point us toward a system. Testing confirms the actual fault.
Avoid parts guessing
Replacing parts based on guesses gets expensive fast.
Intermittent issues
Misfires, sensor faults and drivability issues often need proper testing.
Clear repair plan
Once we know the cause, we can explain the next step and quote it properly.
