Had my new *Used* engine installed and now there are 4 codes... Grrr…

P0501 - Speed Sensor (Speedometer works, No Odometer)
P0134 - O2 Sensor
P0033 Turbo Bypass valve
P0131 02 Sensor Low Voltage

Anyone have experience in these?

The one that gets me is the speed sensor one.
I did some reading, and since the speedometer works odds are its the passenger front??? Do I need a whole new wheel hub?

ABS lights are on.
And the gas gauge don't work.

Is the 2 - O2 sensor codes possibly coming from the same sensor?
How many O2 sensors are on these cars?

Yea me! Any knowledge here will be helpful!

2007 2.0T

Runs great though! :)

Thanks!

Did you put the old ECU in?

Anyone experience this? A fix?
A shop said they'd charge me $99.00hr just to diagnose.
Think I'd rather take my chances on a $50.00 for the front hub assembly and wish for the best...

So non of these codes were present before ?
There is 2 O2 sensors, front and rear, the codes u got for the front.
Maybe it is dead.
There is no speed sensor in the car, the speed is transmitted on the network by the ABS module, so u need to check what codes are stored in the ABS module.
Finally, for the bypass code, did u replace the turbo as well ?
If not, check correct vacuum hoses routing.
If yes, remove bypass valve and inspect diahpram.

Just bought this car for $400.00 with a bad engine. The old engine was toast, it ran... but spit, stumbled, knocked, squealed and blew oil everywhere.
Just swapped out the engine for a lower mileage one. I did not swap the ECU, or the ABS.
All those codes I believe were there (especially the ABS) before the swap.
If the O2 code is just the top O2 sensor, at least that one seems simple enough.
The turbo I did replace. Didn't trust the old one to function properly.
The "new" turbo only has 20,000mi on it, that's why I grabbed it... seems to work well.
How do I get the codes that are stored in the ABS?
I don't think the scanner at the Auto Parts store picks those up? ?
Didn't really want to spend the money on the Tech 2, but? Starting to seem like a good idea if I can figure it out and that what I need to do?

Thanks for your help!!

U need a tech2 or any advanced scanner to read ABS codes.
Where both turbos identical 101% ?
Did u hook the lines going to the bypass valves correctly, better take some photos

Is there such a thing as a cheap Tech 2?
I suppose 3 hours of diagnosis is going ţo cost me $300.00 anyway ?
Going broke already.

I will take pictures in the AM.

Should have been a exact swap though. Both high pressure Mitsubishi turbos.

U can buy a clone for as cheap as 250$.

There are three versions of MHI turbos with minor differences, make sure urs match the old one, check the hose going to the bypass valve is coming from the solenoid (next to throttle body) top connection and not accidentally connected to the wrong port or not connected at all or maybe cracked, if all checks ok, remove bypass valve, make sure no damage inside.

Over here we only got the 14T turbo on the B207R.

"Yes, I kept in the old ECU so it's the old codes still popping up."

"I did not swap the ECU, or the ABS."

Did you or did you not reuse the old ecu off your old motor? It NEEDS to be reused or the new one needs a tech2 to reprogram.

I'd contact Brew City Boost in Hubertus......they will know their way around the ecu better than anyone due to their extensive tuning/engine upgrades. (I don't know if they do general repair work or small jobs but its only a phone call).

Yes, I re-used the old ECU.

I just found that Brew City place. Not far from me at all! I was shocked!
I may drive over there on Monday.

Then check codes stores in the ABS for any speed issues.
By the way, the MHI 14T came in revisions, with minor differences
