Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if the oxygen sensor has been replaced How many miles are on the car?
Does the engine seem to rev high and not have power or is the engine having trouble revving?
Thank you. From the symptoms and the code you are getting I would suspect that the O2 sensor needs to be replaced. When this occurs the computer will stop using the O2 sensor input and run like it is open loop. Does your scan tool read live engine data to see what the O2 sensor reading is?
I don't believe that this app has it. You need to see if it says something like live data.
Sounds good. I will look for your response then.
That should work. Once the engine is warm I need to know what the voltage reading does and how high and low the voltage gets and how quickly is changes. That will help.
