I recently swapped my OBD1 B17A from my 92 teg into my 91 CRX Si, and made sure all wiring was done properly. Now after a few minutes of driving, usually when coming to a stop I get Code9, CYP. I followed the integra service manual troubleshooting, and all resistances are within specifications. :/

I'm at a loss and have no VTEC. I dont want to do any damage by driving the vehicle, but at this point driving is unaviodable. The integra ran fine, and threw no codes, and I did not seperate the dist. from the engine during the swap (so I dont see how the sensor itself could have been comprimised). I have verified that there are no shorts to ground and that the wires are definately pinned to the correct ECU pins. If anyone has any knowledge of this, please help.

 

do you have the wires reversed? i know you said you have them pinned right, but you are 100% without a doubt sure they are pinned right?.. that will cause the resistance to be in spec, but the CEL will still go off.

if you have it pinned right, i would be picking up a new distributor. I beat my head against a code 9 for about 4 months, trying everything to fix it. to make a long story short, a new distirbutor solved my problem immediatly. the moral of the story: test the wiring. if you know it is right, then it was just your distributors day to go..

 

update:

I definately had everything correct and I was certain that my distributor was ok. I ended up re-wiring my OEM ECU connectors from the integra onto my OBD0-OBD1 harness and problem solved! Damn cheap aftermarket connectors were the problem!
