What Happens If My Car Fails a Smog Check?


The DMV requires a smog check for vehicle registration in the state of California. If your vehicle’s smog inspection fails, you have two options: repair the damaged components or stop driving. If your smog check fails, you won’t be able to renew your DMV registration. Your failed smog test may now cost you money in repairs.


What Should I Do Now That My Car Failed Smog? How Much Do Emission Repairs Cost?


If you fail an automobile emissions test and decide to repair it, the cost may surprise you. Many of the issues that can cause your smog check to fail are expensive to fix. Parts and labor for a catalytic converter replacement are typically between $1,000 and $2,000 per unit. An EGR failure on a Ford 6.0-liter engine, on the other hand, might easily cost several thousand dollars, as it would necessitate a new EGR valve, oil cooler cleaning or replacement, and the labor to fix them.


Maybe you’ll get lucky – sometimes all that’s required is a new fuel filler cap or a modest repair like an EVAP purge control solenoid. There’s a chance you’ll be able to get away with a bill of less than $200, but that’s not the norm. If you do have a failed smog test, you can visit Nono’s 76 in Los Angeles, for repairs. The cost of repairing may be less expensive than other options.
