I've recently had my Coolant light come on and then of course the engine light. I've already replaced my thermostat housing with an aluminum one 2 years ago. I just replaced the sensor today and I still have my engine light on. I don't however see the coolant light on anymore. My code reader does show 2 of the same diagnostic codes though. I have one P0117 in Current and a P0117 in pending. I don't think I deleted the old code though. Does anyone know why I have two of the same codes and why...
