So ever since installed my MD spacer i have had a cel.

I just finally purchased an OBD2 code reader (Innova 3100).

This has given me the following info (called freeze frame data) about the cel.

The code was P0444 and the data with it:
fuel sys 1 OL
fuel sys 2 OL
calc load (%) 23.92
ect(F) 118
stft b1(%) 0.00
ltft b1 (%) 6.25
stft b2(%) 0.00
ltft b2 (%) 6.25
eng rpm 1225
Veh speed(mph) 0

I have no idea what the data translates to. ANY HELP WOULD BE GREATLY APPRECIATED THANKS ALL

 

Found this info:

P0444 - EVAP Canister Purge Volume Control Solenoid Valve

From my Book: "Evap. Emission Control System Purge Control Valve Circuit Open"......

Sounds like you may have left a hose off somewhere......easy to do...

ok, well i have searched the forum and that offers this:

sadly i could not register for my350z because the administrator hasn't approved more members or something.

Anyways, anyone mind hosting the pic that DavesZ#3 has attached (first response on the above thread).


secondly anyone know what these stats stand for from my code reader?

1st 2nd
fuel sys 1 OL OL
fuel sys 2 OL OL
calc load (%) 23.92 22.35
ect(F) 118 159
stft b1(%) 0.00 0
ltft b1 (%) 6.25 2.34
stft b2(%) 0.00 0
ltft b2 (%) 6.25 2.34
eng rpm 1225 775
Veh speed(mph) 0 0


THANKS ALL FOR YOUR HELP

 

the stats show the code two times, after the first one i cleared the code, and has appeared again as the same thing. above shows first and 2nd codes freeze framed stats.

Anyone know how to use these?

 

well, i solved the p0444 cel.

It was due to an electrical plug left unplugged

If you ever get a check engine light after installing a plenum spacer it is probably due to a plug left unplugged.

 

Do you mind taking a photo of the plug and posting it here? It might be helpful to some one else in the future.

 

i will next time i take my stb off and my engine cover

 

is the the plug at the throttle body?... that and the MAF sensor are the only plugs I'm aware of during a spacer install...

 

I assume it's the plug at the throttle body. I know that I've forgotten about that plug TWICE. When the ztube is installed and the lower hose connected to the ztube, the plug to the throttle body is nearly invisible.

 

I figured the same thing... that must be what he is referring to...

 

i believe the clip was blue in color, on the gold plate that also has two tubes running toward the cabin of the car. Passenger side.
