Thread: ses light

my ses light is on and the code that is showin me is p0420 catalyst efficiency whats does this mean? and does this fall under my warranty wit nissan to replace?

ok first off what year if your car? what kind of warranty did it have to begin with??
i dont know what the code means but have u taken your car for the re-calls??

77,100 miles, 02 ser auto, bumper to bumper i think till 100k, havent taken it for any recalls

i dunno man but the dealer would be the last place i took my sentra. and id double check on that 100k warranty bumper to bumper cause i doubt that.

i think thats the o2 sensor on ur manifold

thats the precat code... it broke up... change it fast b4 u suck shit in ur motor!!!!!!!!
precat failure..
thats y everyone gets a header lol


take it to nissan and get ALL ur recalls done and change out that precat, then get a header

Cats are warranteed for 8 years or 80,000 miles
