I need some help from people who know more about this stuff. I've tried everything I can think of. 2009 maxima failing emissions with P0014 & P0024 codes. I'm a week and a half late and I need a tag!! This is out of my scope. Can anyone tell me what I should do? I have a OBDII reader and watch while driving. I turn the check engine light off but O2S and EVAP monitors aren't ready...I've gotten the O2S to turn green from doing different tips I've read white a few times but of course the emission places are closed when it did. Now it seems I can't get the O2 to turn green anymore. Has anyone else had this problem? Tips? Advice?

 

You might try a Nissan Maxima website. That being said, these are possible generic causes for your codes on a Nissan:

•Dirty Oil
•Faulty Exhaust valve timing control solenoid valve
•Exhaust valve timing control solenoid valve harness is open or shorted
•Exhaust valve timing control solenoid valve circuit poor electrical connection
•Faulty Crankshaft position sensor (POS)
•Faulty Camshaft position sensor

Also, there's a factory TSB on these codes being thrown on 09 Maximas:

If you can't figure out how to Google this info on your own like I just did in two minutes and fix the issue yourself, then I recommend you take it to a shop and have them tackle the repair using proper diagnostic equipment and tools. You'll save a LOT of money over swapping out parts you don't need until something sticks.

 

solenoid covers are the problem,not a cheap fix
