Emissions faults are a frequent reason for a check engine light and a failed inspection. The system is designed to control what comes out of the exhaust and the fuel tank, and small leaks or sensor faults trigger codes that need correct interpretation.
Common symptoms
What we check
Emissions diagnosis is best done before paying to retest. We confirm the cause, complete the repair when possible, and verify the fault is not present after the drive cycle.
A note on shop equipment
Some repairs cannot be completed safely at a mobile location. After the diagnostic, we will tell you whether the work can be done on-site or whether shop equipment is required, before any repair begins.
