code 9: CYP
my car is throwing a CEL code 9, CYP sensor, checked the wiring and it turned out fine. i tried swapping out the cyp sensor from my SOHC distributor and its still didnt fix the problem, but when i use my SOHC ECU the light goes away, what could be the problem? i hope its not a bad ECU. will a USDM ecu work on a JDM h22a?
Im having the same problem...it comes on every once in a while..it just started doin it too!!! Along with that my EGR CEL is comin on every so often too...im fed up with this crap.
guess what guys? You have a bad ecu, if you check the ohms on the distributer plug 4 and 8 and the ohms are from 350 to 700 ohms that means your distributer is fine cyp is fine it is your ECU, i have same problem and changed eu and all is fine check to see if you wiring harness is fine............ 1
