Exhaust in Solenoids

If the PCM and the lights on the solenoids themselves are changing from on to off to on, then look again at the plumbing.

• tubing from your pressure regulator into the P port and the pressure gauge on the regulator reading 60 psi (in your picture the P port is plugged, but needs a press-to-connect fitting and air pressure of at least 30psi to work properly)
• tubing from port A to one end of a cylinder
• tubing from port B to the other end of the same cylinder

Don't leave any of this plumbing open to the air. It must connect to something or be plugged to prevent the pressurized air from running straight out to atmosphere.

Test manually:
Does the solenoid change when you push the blue manual button shown on top of each one in your photo (with pressure applied to the input port of course)?

Can you add code to toggle the solenoid value at the press of a button?
