Which codes cause limp mode?

I know oil metering pump will, but what all codes will casue limp mode?

I have the following codes:

30 (split air bypass)
33 (port air bypass)
38 (AWS)
39 (relief valve)

I know I installed a 330ohm resistor in each of the plugs, and I thought that was supposed to keep it from getting a code? the CEL doesn't come on, but when I pull for codes, these are there...will any of them cause limp mode?

None of those will cause limp mode.

I would go with a PFC, but I have read that the car NEEDS to be in good health before you install it...

Did you clear the ECU after installing the resistors? (Step on brake pedal while the battery is disconnected)

Are you sure you've got a code 30 and not a code 3? Code 3 (crank position g sensor) will cause limp mode...

You know what...how do you tell? I get 3 slower lights...then black until it starts the 33... But, I had a TPS code when I was messing with it (12) and it was the first code to appear...if I were having a code 3, it would go in numerical order...

Can a TPS go bad and still have correct voltages and not be throwing codes?

Sounds like you do indeed have a code 30...

From fd3s.net:

"Identify the first (tens) and second(ones) digits of each code as follows: The first (tens) digit will display (flash) for about one second for each count, with a one-half second pause between counts. For example, if the first (tens) digit is three, there will be three separate one second long flashes, separated between by one-half second pauses.

There is then a 1.6 second pause between the last flash of the first digit and the beginning of the second (ones) digit.

The second (ones) digit counts flash for only one-half second each, with pauses of one-half second between them. For example, if the second (ones) digit is seven, then there will be seven flashes of one-half second, separated by pauses of one-half second.

In this example, the displayed code will thus be "37".

The system will then pause for four seconds before proceeding to the next code, if any. "
