Code 23?
Code 23?
" 23. Low temperature at manifold air temperature sensor OR
Throttle position sensor error"
Can anyone tell me a little more about this code? Does it pose a danger to any of the internals?
How's it fixed?
I've also noticed, that light will only come on after the car's been driving for a while, and usually at low speeds. If anyone's got information about what's wrong, I'd be more than happy to listen.

Check to see that you IAT sensor is connected properly to the harness (IAT is at base of air cleaner). I got a code 23 before and this was my problem or you might just have a bad sensor. The light only comes on when you are driving for awhile because the computer doesnt start taking information from the sensors until it goes into closed loop (occurs at a certain temperature).
