Ok, my 05 has had a slight leak which sounds to be the passengers manifold. Had it for about 500 miles. Now today enigine light comes on.. says code p0059 heater resistance bank 2 sensor 1..
Possible manifold leak not the case? maybe where cat-connects to manifold? would a small leak in exahust near the area of o2 sensor cause this code, or am i in for something new thats broke.. Where should I start?
All this with only 53,000 miles.. pretty pissed.. Any help appreciated.

 

Bank 2 is the driver's side. That should be covered under the emissions warranty.

 

Yep, your right. Just got under my truck and after playing around noticed that o2 sensor plug for the wire was somehow almost completely unplugged.. plugged it back in an cleared the code so we will see what happens now as i drive tomorrow. Kinda odd it came unplugged like that, especially since it was fine and came on while completely stopped at light..

thanks for the info, without that i never would have though to look on the drivers side.. i assumed bank 2 would be passengers side.

I also looked in depth at where my leak is coming from and i dont see any signs at all but its sure loud leaking sound while driving coming from the passengers side manifold area.. i cant believe the small amount of room on the passengers side, and yet drivers side has a huge amount of room, what the hell do they think when they design this stuff..

also since you mentioned emissions warranty.. how long is that on an 05??

 

Should be 8 years/80k except in California, I think it's 7/70 there.
