The check engine light and all that stuff came on and it comes up code p1135.I just need to know what part I need to get to fix it.Please help. Thanks.

 

front o2 sensor or front air/fuel sensor.

Air/Fuel Ratio Sensor Heater Circuit Malfunction. this is a dead-accurate code and you
have no mystery. your sensor is unable to produce accurate readings. if you leave this
and do not fix it eventually you will get huge carbon buildup and clog the cats and ruin
the rear o2 sensor

get exact part from dealer, do not screw around with aftermarket.
give them vin number so they get the right part also get 2 nuts and gasket

crawl under, rip out old one, install new one. done.


that, or do the real diagnostics and make sure. but I will bet this is the issue

plan on your rear o2 sensor dying within 6 months as well. if you have the loot
get that sensor at the same time
