Greetings. Does anyone know where I would be able to locate RPO codes that are not available in the RPO Database? I have 6 codes that I am trying to locate with no luck. They are E7Z, MX0, M0D, P84, UUB, and 1HV. Thanks for the assistance.

 

I believe MXO is an automatic transmission specifically the 700R4.

 

Does your car have the Bose stereo? If so, UUB is actually UU8.

 

Yes it does. Thanks. That is another one down.

 

when i decoded a friends some 0s looks like Os and vise versa.

just read them more carefully and u should find em all.

 

MX0 = Merchandised Transmission Auto Provisions (O/D)

If P84 is actually PB4, it would = Lock Control, Wheel.

If I remember correctly, E7Z = VSS delete

 

VSS Delete?? Pls clearify... Thanks

 

Cars with the E7Z option had the VSS (Vehicle Speed Sensor) deleted from the transmission. Along with this RPO code you should also have E5Z & E9Z as well. Follow the link below and you will find more RPO codes for the GM vehicles.

Thanks for the information. Any idea what VSS did and what was the differance when it was deleted???

 

I've researched the MX0/MXO code as much as I could on the Internet and through a couple friends at various dealerships, and there are basically no clear answers to it. I know for a fact that I have MX0 (zero) and not the letter O, and I have reason to believe that MX* codes all end in a number. For what it's worth, the below is what I've concluded; there are possibly two RPOs. Mind you, I could be wrong and there is only one, but this is what I have:

MXO (this is the letter "oh") : MERCHANDISED, TRANS, AUTO PROVISIONS, O/D

MX0 (this is a zero) : MERCHANDISING OPTION ONLY-DO NOT CATALOG

This is not the actual RPO describing the trans in the car; MD8 is the 700-R4 automatic trans RPO. If you have a different RPO starting with M, that would be your trans, but you may want to double-check M0D. I don't think that is right.

 

E7Z - KEY, SPEEDOMETER (DELETE)
MX0 - MERCHANDISED, TRANS, AUTO PROVISIONS, O/D
M0D - ????
P84 (PB4) - LOCK CONTROL, WHEEL
UUB - AM/FM Stereo System, Delco-Bose
1HV - COMPONENTS OF WS4 TRANS AM OPTION(PONT) or COMPONENTS OF IROC-Z PERFORMANCE PKG(CHEV)

 

Hello Firebird90,

I think if you would check again, you will find that what you have listed for RPO code E7Z is actually RPO code E9Z. There were 3 codes in this group.

E5Z= Speedo Adapter (delete)
E7Z= Vehicle Speed Sensor (VSS) (delete)
E9Z= Speedometer Key (delete)
