Can a DTC erase a smog check monitor?
If your car has recently been repaired for a problem that set a DTC (check engine on) and the technician cleared the DTC, he also erased the monitors. Also, if battery has been disconnected, replaced or needed a jump-start, the monitors may be erased.
Can a car pass with only one smog monitor?
Note that a car can pass with some incomplete monitors…a maximum of one on 1999 and earlier cars, and only one ( The Evaporative System monitor) on model year 2000 and later gasoline powered automobiles. All monitors must be complete on 1998-2006 diesel powered vehicles.
What happens when your car fails a smog test?
When your car gets a smog test, one portion of the test involves connecting the smog test machine to the car’s computer and checking if there are any DTC’s, and also checking to see if the monitors are ready.

The first and foremost step is to check whether the engine light is off. If your vehicle has active trouble codes, it may stop a monitor from running completely. 2. Check if your Vehicle has a Coolant Temperature The drive cycle starts with a cold start.
Can a smog monitor be replaced on a car?
The EGR monitor can not be replaced, in that it is not a smog component. Emission monitors are internal self-tests which the Engine Control Unit performs to ensure a vehicle is not polluting and is running efficiently. The entire process of self-testing various emission control systems is called a Drive Cycle.
What should I do if my car failed the smog test?
After a smog technician ensures your vehicle does not fall withing the bypass criteria, he/she should look up the exact drive cycle requirement for your vehicle’s EGR monitor and perform the drive cycle on a dynamometer (for safety, as opposed to driving on city/highway) and complete the drive cycle as close to the require parameters as possible.

What to do if your EGR monitor is not running?
Start with making sure your vehicle has no known EGR monitor setting issues identified by the BAR and CARB, and next get in to hands-on diagnosis of what is causing the monitor to either not run or not complete. Since the check engine light is not on, we can be confident the ECU has not found any specific emission component failure.
Can you pass smog with aftermarket cat?
If an aftermarket catalytic converter does not comply with CARB labeling requirements, the vehicle will not pass a California smog inspection, and a smog certificate will not be issued.
Does catalytic converter affect smog check?
Catalytic converter malfunction: The catalytic converter’s job is to turn the hydrocarbons, carbon monoxide and nitrogen oxide released by the engine into carbon dioxide and water. Any problem with this component could lead to smog test failure.
How can I make my catalytic converter pass smog?
Correct Procedure to Pass a Smog Test When Catalytic Converter Performance is Suspect
- Plan ahead.
- Disconnect your battery the night before you start the 150-mile run.
- Reconnect the battery the next day.
- Reset your odometer to zero and start monitoring your mileage.
- Start your 150-mile run.

Are oxygen sensor spacers illegal?
It’s not legal in CA, but legal anywhere else. The “for off road use only” way to do it is to move the rear oxygen sensor to the ‘Federal’ location after the second cat using a new bung and wiring extension. Then the California manifold/precat setup can be replaced by a header or Federal manifold.
What happens if you fail emissions test twice in California?
Failing a Second Time If you can prove that you have taken and failed the emissions test twice, and if you can prove that you have spent a certain amount of money getting your vehicle inspected and repaired, the state may give you a waiver.

Some tests only run when the car sits overnight, or is allowed to cool down for several hours. Most cars will complete the monitors easily with the above methods, but rarely it will take up to several weeks before they are complete.
