I am new to the site and my wife has had the car for 6 months. It is a base 2005 model with 16k on the clock.
I was wondering if the diagnostic code of PO173 meant that one of the 4 oxygen sensors might need replacing? The dealer wants to do more tests but gave me the information of Fault Code PO173 - Fuel System - Control Over Limit - Oxygen Sensor 1 Bank 2 - Burning Ritch - will require further diagnostics.
To be honest I hate the dealers and their high prices. Apparently I had put some poor fuel in the car and so i ran the system to just under a quarter and filled up with Premium Esso. The Check Engine Light stayed off for 47 miles and has come on once again. Does anyone know what Oxygen Sensor to replace with the info above?
Thanks
