My Silverado (2002 4.3L )is throwing thse codes P135 and P161. I need to get these cleared to pass inspection. I don't want to put a lot of time/money into the truck with 200k on it.
P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0161 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
Does anyone have expierence with is throwing these codes? I guess the O2 sensors could be bad. I replaced all four sensors on the truck last year. Which O2 sensors are the heated ones, upstream or downstream? If I can get away with just replacing what is there for $60 or so that would be awsome.
Thoughts?
