Just got all these codes
P1884
P0102
P0445
P0448
P0340
My #2 engine management fuse was blown so I changed that and half of the codes disappeared. These are what's left. (above codes) what's my next step?

 

My number 2 fuse blew again???? Short somewhere??

 

powers :

HO2S.

From the main relay in the underhood fuse box. Look for wire harness melted and shorted or rubbed against a bolt and worn thru insulation. Shake the harness.

 

Is it ok to drive it with these codes. I'm in Boston and need to get back to rhode island.

 

I changed my purge valve about 2 weeks ago with a Hyundai one that I read about on this forum, would that have affected my engine and throw these codes?

 

If it is shorting out. Blowing that fuse turns off a lot of things that the ECU will want to tell you about. BTW, do not put in a larger fuse, can lead to under hood fire. You could unplug the purge valve and see if fuse holds. We won't tell the black SUVs from the EPA that are following you.... With fuse blown, O2s off line, you'll be in open loop fueling and mpg will sink like a stone.

 

Here wiring diagrams for that, in case you don't have RAVE on a USB drive with you. Also, in my signature is a link to a site that has the manual in bite sized pieces you can see on line without downloading the whole RAVE.

I woud suppose you could unplug components to see which one is blowing the fuse, you'll go thru a box of fuses. And it may still be a rubbed wire or a melted wire.

 

Thanks for the quick response!!! Much appreciated. I'm gonna drive back to ri and try tackling this in the am. Most expensive ride back from bean town

 

Ok I disconnected my purge valve and no more fuse blowing but I have p0444 code. All other codes are gone as well. Has anyone had the same problem with the purge valve from Hyundai? Thanks.

 

Ok I changed out the number 2 fuse and reconnected the purge valve, truck has been driven for about 200 miles, no blown fuse..no codes just a blinking yellow light waiting for the code to clear/reset I guess. I go to refill my gas tank with shell 93 octane and I get 20 ft from the station and pop goes my fuse again. Any ideas anyone? Bad purge valve? This also happened the first time, low on gas filled her up with 93 octane and shortly later blown #2 engine fuse and out comes the service engine lights. Anybody? Bueller? Bueller?
