Ok. My car threw code 22 for the pressure valve, and i fixed that, and now its throwing a code 21 for the solenoid. Im starting to get pissed off at this and cant find the problem anywhere. I need serious help.

BTW, I tried the wire splice thing to fix the pressure valve, and thats when this code popped up, and i returned it back to normal, and cant get rid of the solenoid code.
