ECU codes

[turboman1]

Would like to find a list of the codes i built a sled with a 1200 motor and im getting some codes 05, 06, 18 , 21 thanks

5=open or short circuit in intake aire temperature sensor. 6=open or short circuit in water temp sensor..18=failure in servomotor ..21=knock sensor failure.. good luck

code 21 ia a light detonation code.
code 23 is a hard detonation code.

usually octane related, but could be heat related as well. Turn the boost down a half pound and see if you still get the 21. You do not want to throw 23 codes. Serious engine damage comes with the 23 code.

I'm curious....if the sled is a 1200 (M1000 motor) how would it throw a code 21 if there is no detonation sensor?
