New engine. new problems!

I just put a new crate engine in my 07 GXP. It fired up fine, then after a couple minutes started throwing codes and "reduced engine power". P2138, P0449, P2544, and C0561. I'm also getting the service stabilitrak, abs, etc.

I had this problem when I first got the car, but it ended up being the battery.

Am I missing a ground or something simple. It runs fine, but every couple of starts, it has no throttle response. (None, not delayed)

Thanks for any help in advance!

My guess is its electrical. There is a ground on the front of the head. Are you sure you got a good ground.

I did check the engine ground. it's good. I also have zero boost. not sure if it's a cause or effect....

So, you've got:

P0449 : Evaporative System Vent Control Circuit Malfunction
P2138 : Throttle/Pedal Position Sensor/Switch "D"/"E" Voltage Correlation
P2544 : Torque Management Request Input Signal "A"
C0561 : Traction control
* C0561-71 System disabled. Information stored. Invalid serial data received.
* C0561-72 System disabled. Information stored. Alive counter incorrect.

Is this an auto or a manual?

I would:
0. Check your harness connectors at the ECM. Make sure they're firmly clamped down.
1. Check all of the grounds (mentioned in ChopTop's link above) and ensure that they're clean and correctly attached
2. Check your battery terminals, also to make sure they're clean and properly connected. (An bad negative battery connection can act like a flaky ground),
3. Make sure the wiring harness is firmly seated where it connects to the bottom of the engine bay fuse box. I spent a week chasing that one after swapping an engine.
4. Make sure the big (4" x 2" x 2", roughly) harness connector that's near the fusebox is firmly connected. It has one of those lever-action camlock things that secures to two pieces together.
5. Make sure all of your fuses and relays are properly seated.

And, of course, check the harness connectors for the evap, throttle and wheel speed sensors.

But, typically when you see multiple failures like this, it's a ground.

P2138 indicates that there's an intermittent or bad connection involving the throttle body, the pedal and the ECM.

Replacing the battery tomorrow and will check all those connections this evening! Thanks for the help! Btw, it’s an auto.

Charge your battery.

Now a few other questions....

Did you replace the ECM?

BCM?

Wiring harness?

Here's why I ask...an '07 ECM is not compatible with an '08 or '09. Motor shouldn't matter, but harnesses, etc will. Did your motor have a harness already installed? Was it for an '08 or '09? If so, there's your problem.

Everything is the same from the original car except the engine itself. I had to reuse the accessories, as well as the intake manifold/throttle body. I'll toss in a new battery and see what happens.
Every time I clear the codes, I get the same codes back, but not always all at once. Some codes are intermittent, but the reduced power is always there. Hoping it is just a battery! The only thing that is different from when the car had the original engine is the long block.

Hang on fellas! We have a winner! I guess when I put the fender liner back on, this little guy worked its way loose. No I have no codes, but the battery light is on. Seems to run fine. I'll replace the battery and see what happens!

Thanks everyone!

Before you replace the battery, I'd disconnect the negative cable, crank the engine (it won't turn over, but it'll clear any residual charge in those pesky capacitors that are everywhere), reconnect the battery and see what happens. Basically, this is trying to tell the ECM "Hey, I know you're mad, but I fixed it. So, chill."

Takes 10 minutes and it could save you some cash.

Make sure that battery light isn't actually the low coolant light. It looks just like a battery to me. When I first got my car I chased non existent battery problems for a while until I figured out my coolant was actually low lol.

Is this recommend anytime the battery is disconnected?

It's probably not necessary, but it's a good way to make sure that there's no residual charge in the system. Depending on where and what you're working on, you could potentially get a nice little shock if that's not done. To be honest, I've only done this once or twice under very special circumstances.

I had an issue on another car where, apparently, a cap keeping something on that really needed to be off. If you do something that requires serious current - like trying to start the car - it'll discharge any capacitors on that circuit. It's also faster than waiting 10 minutes after disconnecting the battery which isn't guaranteed to work, anyway.

In other news: the headlights on an 05 Boxster S are not fused.

I know it's problem solved, just figured i'd chime in with my 2 cents on the subject for any future readers

I had the EXACT same set of codes popping up on my 07 solstice

It would start just fine, but somewhere between 15 seconds to several minutes later the dash would light up and i'd get reduced power and all that jazz

replaced battery,
replaced pedal sensor,
cleaned TB,
cleaned ECM harness connector,
gave up and took it to the dealership

they called me 15 minutes later

The culprit was one wire in the harness from the ECM, it had developed a crack and the wire itself was damaged. Replaced the harness. Problem solved

Worst part was I thought it was something really serious and I actually drove the car like that for 4 months!! Just puttering around town with the rev limit and no boost because I didn't want to hear that my baby would have to be put down

Well, the original problem has been fixed. It was just the harness connector loose.
Now I have the battery light issue...
Battery has been replaced. Alternator tested off the car. everything good.
The battery light comes on about a minute after starting. It stays on constant while driving.
Hooking up the tester at the parts store says the alternator is not charging. It also says the batter is almost dead. But the car drives fine, starts fine. No issues other than the actual light on? I'm down to thinking it is a wiring issue. Any ideas where to start?
