Check Engine Light Diagnostics questions answered
Can AutoZone's free scan replace a diagnostic?
+
A free scan only reads the code. A P0420 code, for example, can be a bad catalytic converter, an O2 sensor, or an exhaust leak — testing tells them apart.
Will a check engine light fail Texas inspection?
+
Yes. On 1996-and-newer vehicles in Travis and Williamson counties, an illuminated check engine light fails the emissions portion of the state inspection.
How long does diagnosis take?
+
Usually 45–90 minutes. Intermittent electrical faults can take longer.
