I know I'm being annoying posting so much on the EMS forum, please forgive my lack of knowledge.

I just installed an Agency Power underdrive pulley and a COBB Access tuning port.

I'm getting the following trouble codes:

P0039
P0300
U1900


Question is...should I panic? Is my car about to explode? Or is this normal? Thanks for any and all input.

 

P0039: Danger to manifold
P0300: Floorpan structural failure
U1900: Oh ****...

 

j/k

 

P0039: not sure what that is

P0300 Random misfire detected Flash/ON 1 or 2 Misfire ´ (See DTC
P0300 )


U1900 = random AP code, don't panic.

 

 

I neeedzzzz NAWZZZZZ lol...

 

update: don't worry about the 0039, it's a random AP code.

I'll block P0039 and U1900 (or try to). P0300...hmm. I'll check to see if I moved something trying to tighten the bolts on that bloody pulley...

 

Why does this sound familiar?

 

the fast and the furious sir... they made it, you lived it.

 

just spit rum and diet on my keyboard. thx. i have tears in my eyes now!

beers

 

my light went off cause I didn't properly measure the deflection of the belt when I did my pulley kit... you might want to check it again.

 

really,

you believe that? you think somehow the ecu knows the deflection of your pulley belt?

how about you did not reset the kam. as you changed the pulley..

beers

 

The misfire is due to you needing to reset the e-shaft position sensor after installing the pulley. Switch the car to "on" and press the brake pedal 20 times or until you see the oil pressure gauge go to halfway and then fall.

Once done, you can start the car and shouldn't experience anymore misfires.

swoope FTW

 

Flashwing! Your brilliant, that worked like a charm. I had a feeling it was the AP Pulley. And Jedi thanks for the update on the 2 random trouble codes. Since I reset the ECU havn't had a single light flash. Thanks guys.

Once again....11,600 posts, MAAAAYBE a few of them wasted....lol
