California BAR Smog Technician Practice Exam 2026 – Your All-in-One Guide to Smog Certification Success!

Recording the result of the EGR functional check on a BAR smog test is what’s being tested. If the EGR valve operates correctly during the functional portion of the test—opening and closing as it should and effectively recirculating exhaust—the proper entry is to mark the functional pass. This indicates the EGR system is functioning and not contributing to emissions issues at the functional test stage. Not tested or in progress would be used only if that specific portion hadn’t been completed or documented. If the valve failed to function, you would record a failure under the functional category, which is why the passing choice is the correct one when the valve works properly.
