Newbie here needs help with P0053 and P0135

[Sstevieboy0208]

First thank you guys for all the help in the past and this is the first time posting. I have an issue with my 05 suburban 5.3. Not mu first GM and probably won't be the last but it does have codes P0053 and P0135 and when I clear them they come back by the second time I turn the car on. Haven't changed anything yet but hoping that you guys can point me in the right direction. The thing is that the codes come back fast. Usually when I cleared them the car was warm not sure of that makes a difference. But I was thinking about changing the 02 sensor but want to make sure before I start just throwing parts at it. Hopefully someone can help me here. Thank you all.

O2 sensor is bad bank 1 sensor 1

check the wires for damage first.


the heating unit is pulling too much amps OR is dead aka not pulling enough amp.


it's a good idea to replace both sensors at the same time just in case sensor 2 is "weak"..


I do recommend .
if you can afford it i'd replace all 4 sensors USE ONLY OEM sensors

for optimal performance..

Do what Brent said about the sensors and I agree, do all 4 if you can.

We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. While you may have posted pertinent info in your first post, you may forget to do it again and the info is needed by us anyway. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.


If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.
