Thank you for trusting us with your Toyota questions. I will need some information from you to get started with this isuue. Are the codes listed above the only codes stored in the computer memory? Did you replace the MAF sensor yourself before or as a result of these codes? Do you have access to any dignostic tools such as a digital volt/ohm meter?

Independent shop, looking for additional information not available on all data. I should rephrase the last part of that question. I did have a blown fuse. Looking for the route possible cause. Thinking shorted mass air flow but I'm open for suggestions
Toyota Mechanic: Boxer54, Toyota Technician replied 1 year ago

OK. Do you know which fuse was blown?

Found it. Heat shield bounce off of rear catalytic converter shorted O2 sensor wires
Toyota Mechanic: Boxer54, Toyota Technician replied 1 year ago

That sounds right. Was going to give you a list of everything on that fuse. Glad you found it. If I can be of any help in the future, please let me know.
