Help with cel on pw0

[Grimm Reeper]

Me and a couple of friends just completed a B-Series VTEC swap in 90 STD Hatch. Now that we actually got the motor to crank, we checked the ecu and it's throwing a 4 and 21. Now we know that those are for the Crank Position Sensor and VTEC Solenoid Valve, so were looking over the wires and need help with finding a way to make the codes disappear, the right way

Could just ba a bad sensor in the dizzy, and a bad vtec solenoid. Do you have a extra dizzy laying around? You can check the vtec solenoid by giving it power and listening for a clicking sound. Also check the connections at the dizzy,and vtec solenoid. Triple check the mpfi wiring at the ecu also.

Don't have one around, but were going to go at it again this weekend, but thanx for your help man

Code 4 is gone; helps when the DPFI-> MPFI harness is wired correctly by the maker. Code 21 is being worked on last I heard. Was a fun swap to do.

I know for the fact all sensors etc are good on that swap, make sure youve got the solenoid pinned to the correct location on the ecu, its only 1 wire.

Yeah, it was the Ebay harness that was used - part of it was wired wrong and other color wire was used at the ECU end. It was a freakin' mess. We got it figured out through. Going to work the code 21 tonight a bit.
