That's Cylinder #8 misfire for that code.

Nope. That is not an error. Toyota says a P0308 = cylinder # 7 misfire.
Toyota shows the error codes starting with a P0301 = misfire detected. Code
P0302 = misfire cylinder #1.

That's odd, my OBD II link shows P0308 as cyl. 8. P0307 would be the code
for cyl.7

One of our data sources is in error.

Jeff

I agree. I have never seen that numbering system before either. Normally
P0308 would be # 8 cylinder not # 7. It looks to be a Toyota Trouble code
chart so it may be Toyota decided to do things a little different.

I suspect an error on the Toyota trouble code chart. The ONLY reason I say
this is that the whole point of the OBD II convention is to standardize
standard codes that all vehicles might generate. At least one of the
problems with OBD I is that automakers could make thier particular code set
unique, this allowed mechanics to claim they had to learn lots-o-stuff and
buy lots-o-equipment, therefore they could charge lots-o-dollars for service
that should be reasonably cheap. If I can learn the code set and gather the
codes from lots of vehicles, then I could charge a particular fee. But, if I
had to attend training clases on all of the cars that I might offer service
for, and they all required specialized unique machines, then I could set my
charges considerably higher and make a strong argument that my charges are
justifiable.

Of course, if the guy down the street charged less, then he would grab some
of my customers. But, if we met for beers after work and agreed that the
cost of doing business had gone up because of federally mandated systems,
then we could both raise our prices and get away with it. The consumer was
getting royally hosed under OBD I, and OBD II was created to remove the
abuse that OBD I created. This would make it a requirement that P0308, for
example, should always mean the same thing on any car that can generate the
code.

Clearly, all cars do not generate the same codes. But, OBD II says that if a
code is generated, it always means the same thing. This scheme makes
allowances for Manufacturer Specific Codes -- there are codes that Fords can
generate that Toyotas will not generate -- but the P0308 code that the OP
reported is not one of them -- all codes that are P0nnn are among the common
code set.
