What do you mean the technician cannot show the codes

personally, it sounds like a communication error between the vehicle computer and the scan tool

can you confirm this is true?

    The technician may not have had the proper equipment. I took it to another shop and they were able to pull the codes.

Cleared check engine light. How do I pass smog check?


Clearing the Check Engine light does not repair anything - it only turns off the light and clears the error codes. The problem(s) that caused the light to occur are still going to be present and the light will probably come back on, anytime from a few minutes to a few days depending on the problem(s). What you NEED to do is to extract the error codes that come with the light and take the corrective action(s) to repair the deficiencies. That will probably make the vehicle able to pass smog checks. Of course, now that you've cleared the Check Engine light, you've also erased the error codes, so you will need to wait for it to return to get the data you need for repairs.

run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

CEL P0431 but passed smog emissions in CA - how can I pass emissions if the CAT is damaged? Could it be another issue?


Maybe not your answer, but it is related: Before going to have your car smogged, check your gas cap. Check the condition of the gasket, or o-ring, inside the gas cap. If is already drying out, full of cracks, get a new one. It will not pass the visual inspection. The smog technician, salesman, will try to sell you a new one for $15 when you could get it for $8 at your local auto-parts store. The technician will tell you that if you do not get it right there and then, he will have to fail your car on the visual test and you will have to comeback to have your car re-smogged again.
The cap might still be doing an OK job of sealing the tank, but it won't pass the Visual, especially if the tech wants to sell you a cap. You can tell if the cap is doing its job if you hear a hissing sound whenever you open the gas cap after running the engine fro a while. If it is not providing a good seal, then you might get a check engine light with a code about a failure in the evaporative system.
Just a little thing to check before you go and put yourself at the mercy of the smog tech.
For $15 you could get a locking gas cap, which might be a necessity now with gasoline prices being what they are, now.

MIL/Check Engine Light will not come on during start up to pass smog 2000 Ford Mustang


There should be a 10amp fuse in the fuse box for the instrument panel that powers the light. The light is grounded by the computer.
Have you checked the fuses in the passenger compartment ?

Mil/check engine light smog test failed


If you are a DIY'er you can get a OBDII scan tool that connects to your laptop that can tell you the error code and allow you to reset your check engine light.

Check out http://www.fitityourself.netau.net/OBDII.html

Sometimes the check engine light comes on if you did not fit your gas cap tight enough. You need a code reader to find out the error code to help solve your problem.
If it is something simple (like a gas cap) and you do not want to get a code reader to find out what codes (problems) your vehicle computer is saying there is. You can try disconnecting the negative battery lead for 5 minutes. This should reset your check engine light. Drive and see how long it takes before it comes back on - this may help you pass the smog inspection...

No AIR pump


Your vehicle came with a smog pump. It may have seized up (probably breaking the fan belt) and my have simply been removed by a mechanic at an earlier time. It is located below the alternator on your vehicle.
If there is no pump but a bracket to hold it, it has definitely been removed. Vehicles will often pass a state smog test without the pump. It only works during engine decelleration (when you lift your foot off of the gas pedal)
