Hi all, 2012 Toyota Prius Four 210K miles Headgasket already repaired, HV battery upgraded newer OEM modules, ABS Brake Acutator Fixed so not any of those. I've noticed my exhaust smells like alcohol, and this code just popped out. Its frustrating because I just replaced the HV battery, yet I don't think that did anything. I was reading that the P0171 code is likely fuel injector or pump related, while the P014C is likely the 02 sensor crapping out. Was wondering if anyone could help with some diagnostic suggestions. I have Torque Pro and an OBDII sensor, was thinking I might be able to watch a graph of the air/fuel but don't know what I'm really looking for. Thanks!
