Can someone define what these MEAN? Obviously it's all 4 O2's.

I currently have O2's in the TPIS long tubes, and O2 simms plugged into the harnesses for the post-cat sensors. They are all nice and ziptied 1-1.5" away from the headers, which should be PLENTY of room to stay away from heat. Any ideas folks? It's obviously not something bad enough to throw the light on, but they are "current" codes.



P0135 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 1 Sensor 1
P0141 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 1 Sensor 2
P0155 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 2 Sensor 1
P0161 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 2 Sensor 2


Thanks in advance!!!

Heater circuit codes

Hi there,
These 4 codes are not for 02 sensor performance, like the sensors are not working. These are for the actual heater circuits, within the o2 sensors, which warm the sensors, for faster reaction times.
Please check your #15 minifuse, at the underhood electrical center, and see if it is blown. I think it may be.
You have spares there, and should install another one, and see if it blows again, when you start the car cold.
I think either there is an internal short in one of the sensors, or the sims, causing the condition.
Please let us know what you have, c4c5

Check your ground source next

Hi there,
From everything I can gather, you can only be experiencing one of 2 things, either there is no power getting to your fuse, or the ground source is not there.
You are not blowing the fuse, so the short to ground is not a possibility. So, your next move is to check you ground side, which is splice pack sp122, located directly below the right side of your engine, under the cylinder head. Its difficult however, once you get underneath, you should see it. It will look like a connector, bolted directly to the engine block. This is your grounding side to the o2 sensors heaters.
Let us know if it is loose or anything, c4c5

Dustin ... you brought up a VERY old thread!
If you want to get to c4c5specialist on this specific problem, probably best to go to corvettemechanic.com, where he is a regular. :idea:
Good luck! ...
