My 05 ford focus Zx3 2.0L I went to smog for twice still don't passed the smog test the reader said cat is not ready evap is not ready 2 air is not ready what I have to do

Did you disconnect the battery recently? Or have the car worked on to correct a check engine light problem? And they reset the codes?

When this happens (loss of all power or code reset), the computer will run all its tests on all systems, and set a 'ready' condition when the tests are passed. Some tests require multiple 'drive cycles' or specific conditions (less than full tank of gas but more than 1/4 tank) to complete the test. Until all (or a specific number - some non-critical tests may be exempted) tests are 'ready', the car will not be passed. The assumption being that until a test is successfully completed, the computer may discover a problem with a system, one that would fail the smog test.

If you're confident that all problems have been fixed, you need to run through enough drive cycles so the computer can complete all required tests. Most ODBII code readers can also read the readiness of the systems. And most parts stores will read your codes for you (and system status) or let you borrow a reader.

My 1999 kia sephia wont pass smog test

You will need to get it scanned and get the codes for the problem. If it failed the test due to emissions I would almost guarantee it will be your oxygen sensor or cat

I have 2000 ford contour my engine light came on i took my car and got a reading which said failed canister vent solenoid. what does that mean. Is it serious

The solenoid is for an emissions device called an evaporative loss canister. It would probably not affect how the engine performs but it would have to be replaced to pass a smog test.

Prerunner wont pass smog due to engine service light

Not positive on this so consider only. The o2 sensor is what actually tells everything else what is going on with emmission and everything else adjusts to what info it relays. The o2 is also subjected to extreme temps and cooling cycles. So, instead of spending money on no answer diagnostism give replacement of o3 sensor so consideratio. If you choose to replace, wd40 and let exhaust cool down. Good Luck.

Car passes emmission test but fails due to codes in computer

ok code 0300 is a random multiple cylinder misfire. probably ignition related is my guess. i would check the coil pack and ignition module and go from there.
