Check Engine Light

[ChrisPerna]

so i pulled some codes out of my pathfinder and i got a P0463 P0182 P0174 and a P0420. I need help=[ i cleaned the Mass sensor ans still no luck.

[k9sar]

is that the order they were in?

 

I think this is right (though I don't have an R50)

 

P0463 Fuel Level Sensor

P0182 Fuel Tank Temperature Sensor

P0174 Fuel System Lean, Bank 2

P0420 TW (Two-Way) Catalyst System, Bank 1

Try changing your fuel filter and running some fuel injector cleaner to see if that clears anything up perhaps?

i ran 2 tanks of tecron and lucas and no luck. fuel filter is brand new too

[ChrisPerna]

anyone?

[Towncivilian]

Check fuel lines, make sure they're not cracked or worn. Is your gas gauge accurate? Sure it's not a bad batch of gas? Try getting some gas from a different station, and run some 91 octane fuel for a few tanks.

Well since it's an 03 with the 3.5L you're supposed to run 91 octane all the time, but I don't think not doing it would cause the SES light to come on.

 

Sounds like you have a bad 02 sensor and maybe fuel gauge sending unit

been running v-power in it since i got it. and the gauge is not correct.
