Code U0D07???
 

I have an engine warning light on in my 2001 Elantra. When I scanned, I got a code of U0D07 but have not been able to find what such a code means. Does anyone know?

Thanks.

Not a valid code, you is wanting a "P" (powertrain) -xxxx type code (x's = digits)..

What scanner did you use? First, I'd suggest a new scanner because there are no "U" OBD-II codes.

BXXXX = Body Codes
CXXXX = Chassis Codes
PXXXX = Powertrain Codes

(XXXX = numbers, no letters)

Code issue
 

I have a 2001 Hyundai Elantra with the engine maintenance light on. I used a ScanGauge II to find the code. I got U0D07. I reset the car and checked when the light reappeared with the same code result. What does this code indicate?

Thank you!

Re-read posts 2 & 3 above....

I want to see a P-xxxx type code, then I can tell you where to start.

As "Buddy" over at Sturm says --> "Help us to help you"

Let me see if I can say this again so you will understand:
U0D07 is not a valid OBD-II code. Use a different scanner.
That U code is a communication error with the ScanGuage II.

OBD code
 

I used two different ScanGuage II units, both reading the "u" code.

I assume there is a problem with the output plug connection under the dash. Is there another output plug connection under the hood (like on my Toyotas)?

(5) day now and you cannot drive through a Auto-Zone, Advanced Auto or Pep Boys for FREE scan and get a P-xxxx code(s)...

No, there is only one OBD-II port and it is under the dash. Forget the ScanGuage. Get the computer read by a real OBD-II code reader. Hyundai cars require a special (read: different than normal) cable to connect the ScanGauge.

Thank you.
