I got the 0503 code witch says i have a bad front Oxygen Sensor on the right cylinder bank..

Anyone know where this is?

and i was wondering what problems will i see with this? Bad performance? Bad gas? What?


Any last i was wondering anyone know where to get one for cheep, I do not want to get eaten by a Nissan dealer.


Thanks

 

Bad performance + Bad gas mileage...yes
Front right bank would be the o2 sensor closest to the driver coming off the exhaust. (under the engine)

 

this just helped me a whole lot http://forums.maxima.org/showthread.php?threadid=235667

 

It's the one near the oil filter (by the passenger firewall) http://www.courtesyparts.com/A32_O2-sensors.html

http://www.oxygensensors.com for the cheapest price

 

Thanks everyone

Witch one do yall recomend...the Universal or OEM? The walker one for 44 bucks...will that do?

 

OEM is plug and play For the universal, you'll have to use your old connector and splice the wires (I think that's what they call it) http://www.automedicsupply.com/walkeruniv.html
