    I meant PCV valve. Yes, it can cause a smog test failure. These valves are cheap and easy to install yourself in less than 5 minutes.

Why didn't you ask your mechanic what this was? I never heard of a PVS. I have heard of a PVC valve, but that is not likely to fail your smog test. Does the car have any trouble codes?

    The PCV valve can cause a failure of the smog test. Buy a new one at an auto parts store and replace it yourself iabout five minutes.

No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.

Failed Smog Test - 4 codes for 2001 Isuzu Rodeo

Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
