Question about Nissan Sentra
The light came on when it was -18 outside and I drove it back home from work. What could be the problem. I checked my gas cap and it is fine
You will need to get the computer scanned for trouble codes to proceed.
It should still be covered by the factory warranty.

SOURCE: Check engine and VSC lights on
I talked to you on the live chat, and I think that you may have missed the end of my typing...
What I went on to say is that more often than not, on the 02 4Runners, the Check and VSC lights in tandem look mainly after the emission system, and, since you stated no issues during the road test, I would guess that it is a fuel issue (too full/loose gas cap). But, if you can get the vehicle scanned, I will be very glad to provide you with more and better info if you provide me with the DTC codes. That would require your guy or an autozone hookup to a scan tool. I hope my clarification helps; and the graciouness of a FIxYa rating for this question would be greatly appreciated

Yes, the gas cap will cause the Check Engine Light to come on. Will set code P0441 if I remember correctly. It should be okay to drive it. If you would like to confirm the code, take the truck to an auto parts store like Autozone and have them hook up their scan tool and read the code. If its P0441 it will probably be something like EVAP or Evaporative system leak.
Its an easy enough fix while your there too, just pick up a new gas cap or you could pick up an OEM one from the dealership.

Your problem is in the evaporative emission system which is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. The light coming on can be caused by one of the following:
1. Defective or loose fuel cap
2. EVAP canister or hose cracked- not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. You have tried the easy fix, the gas cap. Finding the leak now will require special equipment and testing procedures, might be better left to a professional.
Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.
