Last thursday i hop in my car and start it up and there it was the "service engine soon" orange light. being worried the next day i took it to Autozone and had it read. the code that was found was P0135. i check what this ment in the sticky and it was 0901 which is front heated oxygen sensor right bank. which is simple enough i have 99 SE-L with california emissions. i was just wondering which sensor this is, i looked one www.oxygensensors.com i would like to get the DENSO OEM but i am not sure which is the right one i need do i need part "234-3095" which is for front mainfold before catalyst on the left or do i want the "234-3098" front mainfold before catalyst on the right side? any tips on which to get would be greatly appreciated also how many o2 sensors do the maximas have 3 or 2 is there one after the CAT my cas is a 99 SE-L it is technically 99.5 being built in FEB 99.

 

can anyone offer any assistance as to which part # is for which sensor on a 99 with cali emissions? someone must have done this before any write ups with pics would be appreciated also

 

I'm just as stumped as you are. the same code came up for me and i'm not sure which sensor to buy. Every site i find lists sensor locations for fed spec maximas. I've never bought an oxygen sensor before so I don't know if they come tailed with a harness or if they are just bare wire and you have to connect them yourself. And are they all the same sensor?

 

am not sure which sensor it is and its all very confusing let bank, right bank front rear what the H*ll does that mean. i don't wamma get the wrong one because they are so darn expensive so if anyone could point me in the direction of which i need based on the cel code that would be super

 

anyone has any idea how many O2 sensors the max have
