Just put my motor back in my car, and threw code 21. Reseted the ECU and code 21 was gone but then 22 came on. CHecked all wiring and everything is good. Took off vtec solenoid and checked the screen everything was clean. Reseted the ECU again and 21 came back and 22 is gone, HELP!!!!

what car/ model?

was it working before you took out the motor?

 

yes was working before, took out motor, 95 OBD1 GSR motor, 98 Acura Integra GS chassis

 

pretty sure 21 is Vtec solenoid valve and 22 is the vtec pressure valve

if everything was working before, I would redo the wire connections, if they are not soldered solder them and cover with heat shrink, also check your oil level
