After my Maxima started misfiring for the second time in two weeks, I have checked the ECU error codes it was giving. However, together with knock sensor and 5th cylinder misfire, I have gotten a code which is not on the website. It is 4 longs and 12 shorts. What does it mean? it is not even in the dropdown menu to have 12 short flashes! Is it a sign of a faulty ECU?
Please help!
Did anybody else have unknown codes generated by their Maximas?

 

Ok 0412 = upstream oxygen sensor high voltage fault (right bank)

 

What about 1406?

 

No such a thing..

 

Thanks. I found that my problems stemmed from clogged AC drain line. AC water was dripping from underneath the glove box on a passanger carpet, and on ECU unit. Results: possibly will need to replace an oxigen sensor, knock sensor and may be more...

 

What about 14 03? I keep getting it.

 

I've gotten a 1406 accompanying an 0302 EGR code and other 14xx codes have been reported. The FSMs, Hayes, Chiltons, etc. have no reference to them.

An actual scan tool would probably give a clearer picture as to what is actually being reported.....

 

I got the SES light (Again after resetting it before) and got the same code: 0413
the website for ECU codes doesnt even have 0413 as an option.
I remember someone told me this code is for an O2 sensor, can someone confirm that for me?
