That indicated to me that I needed a new CYP sensor. Can't buy the sensor, had to order a new distributor housing. Bought OEM housing from Majestic Honda via the internet. It arrived, took coil and ignitor from old housing, put in new housing. No brainer. Also replaced cap, rotor, plug wires and plugs, all new OEM parts from same Majestic Honda.
Installed new housing, and associated parts. Started car, same error code and same rough idle.
Did the same diagnostic check as before on pins 3 and 4 of the wire plug coming out of the dist. Same reading. Instead of the expected approx. 800 ohms, got a reading of 0.
Took new housing out, took cap off, checked resistance between the to connectors right at the CYP. Reading zero.
I'm stumped and wondering if the part could have been bad from Hitachi. Attempted to contact Majestic Honda, but have not yet received a reply.
I regret not checking the resistance through the CYP prior to installation, but assumed a new part would be good. I don't see what else it could be since the first test at the dist wires pretty much rules out everything but the CYP.
