So when you clear the code it keeps coming back? I have tuned many SD cars on both air temp sensors and have never received that code with them working properly.
Why would pin 77 be cut? I can't find where he might have been connecting on the other end. Do some folks like wideband on that pin? Looks like it is the Fuel Temp Sensor wire....blue with a white stripe.
Figured it out....for whatever reason he cut the fuel temp sensor wire. That triggered the code. I attached it back and it went away. My guess is he thought it was rear o2? Either way I am good to go now.......thanks for all the help.
