Hi,
Are OBD II codes universal or unique for each model? IF yes, where can
I find a website that has those DTC info listed?
Thanks.

codes that are universal for every model although not every code applies to
every model. For example, an in-line 4 cylinder engine does not have a
"bank 2."

Check out http://www.obdii.com/codes.html for a list of universal codes and
links to some more explanations of how OBD II works.

Codes that begin P0 (P-zero) are mandated by the federal EPA and are
identical in all cars sold in the US and Canada.

Codes that begin with P1, P2, etc, are "enhanced" codes that are NOT
mandated by the EPA. Automakers add them at their own discretion.

Ray O has given you the main site for the mandated codes.

For Toyota specific codes, you need to know the exact number, the you can
punch it in here:

AutoZone in the US (other than California) will read your codes for free.

AutoZone in California will now let you use the scan tool yourself to pull
the codes. And they let you use the tool for free.

I'd like to explore the enhanced (P1 and P2, etc.) codes. The lists that I
have seen seem to show that while all codes are not always used, most codes
that are used always mean the same thing. That is, all cars won't produce a
P1234 (ficticious code that I pulled out of my ass), but when a car does
produce a P1234, then it normally means the same for all cars that produce a
P1234. I do not argue that the codes are enhanced, I conpletely agree that
they are. But my very limited experience is that codes are uniform with a
few exceptions.

P1, P2, P3, etc codes are manufacturer specific, as they are not mandated
by the EPA.

It wouldn't surprise me to see some standardization of the code numbers
between manufacturers, but they are not forced by law to make them the
same.

Actually, today there are only P0 and P1 Codes. Check it out ...

http://www.obdii.com/dtcanatomy.html


But, you were right, only P0 are standardized by regulation, the P1 codes
may or may not carry over among different manufacturererers.

Got this from a class I was in recently, thought it was interesting.

How to basically read OBDll Standardized Diagnostic Trouble codes.

The codes start with a letter:

The trouble code area:
P- Powertrain
B- Body
C- Chassis
U- Network Fault

Who created this code:
0- SAE defined code
1- Manufacture defined code
2- Manufacture (they ran out of codes for 1 so they expanded to "2")

System:
0- Total system
1- Air-fuel control
2- Air-fuel control
3- Ignition system or misfire
4- Auxiliary Emission Controls
5- Idle or speed controls
6- Computer system (PCM or I/O)
7- Transmission
8- Non-computer controlled Powertrain

The last two digits indicate the specific problem area


So the code P1711 would tell us:


P- Powertrain
1- It's a manufacture's code
7- Transmission
11- Transmission oil temperature circuit out of range



and the code P0300 would tell us:


P- Powertrain
O- It's a SAE mandated code
3- Ignition system or misfire
00- random misfire detected
