I HAVE A SWAPED 94 ACCORD THROWING A CEL AN ITS VERY SLUGISH AND NO VTEC ITS THROWING CODES 4,10,20,6 AN ITS VERY HARD TO START AFTER IT SETS A FEW HOURS ANY ANSWERS ON THIS

 

Here are the codes you listed:

-Code 4 - Crank Position(CKP) Sensor
-Code 6 - Engine coolant temperature
-Code 10 - Intake air temperature sensor
-Code 20 - Electric load detector

I'm not sure about code 20 as thats the first time I've heard of this. I'd check the connection at the sensors on code 4, 6, and 10 to see if they're connected to the sensors and not loose and also use a Digital Multi Meter to test the circuit and if it tested out good then OHM test the sensors and compare those numbers you got with the given specs. It's either the sensors itself, wiring, or PCM that is cause those codes to come on. If indirectly test the sensors(load), the whole circuit should be good and only thing left to check is the sensors. Hope you get where I'm trying to go with this.

I'd search up on the Resistance of each sensors to see what they are so you know if it's under or over the given spec. Good Luck!
