I need help figuring out what error code p3920 means.... I googled it but nothing came up...

Please help!!!!

 

not a valid code, should read P0XXX or mazda specific, P1XXX

 

That's what I said but that's the number the scanner gave me and the other one was P0201 which reads "injector 1 circuit fault"

 

free bump. good luck finding the solution

 

Here they all are for the RX8

Thanks ricky!...


Do you guys think it has to do with the scanner? Should i use another scanner next time my light goes back on?

I thought it was my o2 sensor saying my cat was bad (missing) but i've never gotten a check engine for that (according to the scanner i used). I did the spark plug fouler trick... Apparently it worked for me.
