I have a 1996 Maxima and the check engine light is ON. I have put a new High flow Cat on and since my car is California emissions rated it has a O2 mounted into the Cat. I drilled a hole in the new High flow cat and mounted the new O2 sensor in. The car is now kicking codes PO135, PO136, PO155 Can anyone help me find a resistor for the Cat O2 to bypass the Bank 1 Sensor 2 O2 sensor. I think this is throwing off all O2 sensor codes because its not sendong back a good reading to the ECU. The car has 3 O2 sensors on it and I have replaced all with new OEM sensors. I also would like to know if anyone knows the resistor level for the O2 sensor on Bank 1 Sensor 2 so I can buy a resistor and bypass the O2 myself. Send me info to megaram2001@yahoo.com Thank-You

FIXED!!! The problem was the fuse for the O2 sensors was blown so I replaced with a new 15amp fuse and No More Check Engine Light.

theres a fuse for this!! i've had the same problem after y pipe and highflow, heater circuit malf. codes, changed them all and cant get them to go away, which fuse was it?

The fuse is located on your main fuse box under dash on drivers side. The location should be on the panel you take off fuse box. Facing fuse box it is 6th or 7th fucse down on right side should say O2 Sen on panel. It is a 15 amp blue fuse. Hope this helps. Then clear codes with OBDII code reader. Good Luck!!

yeah im handi capped, i went out after postin and found it right away, i swear i checked before for a fuse and couldnt find it, the light has been on for like 10 months, cleared em today with the scanner and havent come on yet. i even called the nissan stealership and asked if there was a fuse for the heater circuit and he told me no and that it could be thousands of things and that i need to bring it in, def. glad u posted about it though, now i can go to emissions with one less thing to worry about
