All right, engine light came on (for my '96 3000GT SL) and is reading off P0400, which is for emissions. At the moment there is a fairly large exhaust leak coming from the flex section of the downpipe. My question is, could the exhaust escaping from the flex section, that is, a lack of exhaust gas flow throughout the entire pipe, cause my O2 sensors to register a CEL for emissions? Or am I barking up the wrong tree, and that's not possible?
Say that the exhaust leak IS the problem. When I get it replaced or fixed (should be sometime over the next week), and the leak is gone, would simply erasing the engine code with the OBDII take care of everything?
