I tested my new OBD2 Scan tool on my Mazda 626 and got the following Diagnostic Trouble codes but I cannot understand what they mean:

P1474:

P1479:

P1703:

Hello. Guys, give writing tips about Code Scanner. How do you use it? I tested my new OBD2 Scan tool on my new car and got some Diagnostic Trouble codes. I try to find something on the net but I cannot understand what all that means. If you have any advice, please share. Thank you all in advance.

 

Clear the DTCs, re-set the monitors, do at least 2 drive cycles and re-check the DTCs!

If you get that many DTC's its time to seek a service shop to help you. If you have to ask then you are not really DIY savoy for ECU diagnostic's. This is not a self learn area for DIY.
