Variocam Plus Solenoid testing ... stroke length ?

David Gray · 2019-05-16T17:37:05+0000

All, 03 C4S with 58k. After getting lumpy idle and P0022 and pulling the Bank 2 Solenoid for the variable cam timing, I am testing on the bench. I used some mild solvent and now can actuate it with a 12V supply. It moves and I can see ports in the valve body. However, they look as if they are not fully opening in spite of a good activation feel when the solenoid pops. (NOTE: D/S Bank 1 solenoid can be pulled with minimal work, P/S bank 2 requires removing bumper cover, hear shields, (both) and muffler in order to access the screws.) Anyone know the correct stroke of the valve ? I have a new one in bounds (returnable) but I am trying to learn a bit more about the system and determine if this solenoid is faulty or if the problem lies deeper. Thanks David
