CHECK ENIGINE CODES 223 AND 232

1992 Volvo 960

1992 Volvo 960 6 cyl Two Wheel Drive Automatic

I just had a new head and cam put in my car now there is a lifter tapping noise and the check engine light came on with codes 223 and 232 I found 3 vacuum leaks and I fix them. I need to know what the codes are and how to clear them

Hi j. Dunc,

223 = No idle valve signal.
232 = Lamda rich/lean at idle.

Check the idle valve for functionability and wiring socket connections.
