Got a code...any ideas??

[narb04]

My car just hasent been running strong. Its kinda sluggish. I have a check engine light due to no cats and test pipes, but i scanned the other day and i saw:

P1557

Not really sure what this means. Any ideas?

Do you have this code:

17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent

Well kind of. The print out from the dealer looked exactly like this:

17965 P1557 035
Turbo/Super Charger Boost Sensor (A) Circuit
Value above upper control limit

Sounds like a bad N75 valve or a leaky line coming off of the N75.

[narb04]

I agree. the dealer thinks its a bad ECU. hahah, Think its possible?

[narb04]

oh, i amost forgot, he said that i was boosting 1.8 bars??

1.8 bars? I hope you have GT28's if you're boosting ~26 pounds.

Agreed with jerbel. Check the N75. I have a spare working one (or at least I think it's working) that I can hook you up with. I bought a new one from ECS for around 102 bucks.

So the dealer pressure tested everything and are convinced its my ECU. They said that the N75's were good too. What about my DV's? Could that be a problem? I have Evo DV's.

if you have a warranty let them fix what ever the hell they want.
