it means the engine cannot run off the sensors it can only run off its base programing and minimal input from certain sensors. A car usually runs in open loop till it warms up and all the sensors can be read with accuracy. Its saying its having a hard time heating up and reading the o2 sensor.btw what does 'Lengthened time needed to achieve closed loop' mean?
The codes listed state upstream as the downstream is used mainly for emissions reduction. Bank 1 sensor 1 (4 cyl=1bank, sensor 1= first from engine)Suggest that you go onto the Autozone site and plug your model and year to get an idea what the O2 sensors cost. They also have a do it yourself video on how to change it and also they will rent you the tool which is refundable. Ask them to clear the codes and see if they can determine which sensor is the problem. ( If that is the problem) up stream or down stream.
I will post a pic when I get the change of my muffler. it's the part that connects to the muffler to the rest. before it was fine wasn't causing any issues. had it welded but the winters up in Buffalo are brutal. especially in the City and it came undone yet again. been trying to save up money to replace that piece but i forgot the name and it's still has yet to come to me what the name was. Thanks All for helping me!
