I got an error code for the CKP - Crankshaft Position Sensor on my 1994 Honda Accord EX 4-cylinder. It is built into the distributor. I took out the distributor, tested the leads on the sensor, and they all showed proper resistance. I went ahead and tried to replace it with a new distributor, but that didn't help either. I'm still getting the same code (in addition to a TDC- Top Dead Center code - also built into the distributor) and the engine is running all out of time, missing, etc. It was a very sudden onset, no gradual breakdown, so it seems to definitely be something electrical/sensor, but I can't figure it out. Any help? Please?

 

That code sucks a fat one.
I've been through with a customer. we tried 4 dist and one was an OE housing straight from honda.
She sold the car.

 

Thanks! Turned out to be a broken camshaft.
