Figure 1
A popping noise may be emitted from the (PEDES) A..I.R. management valve. This noise may occur due to one of two possible causes. It may be caused
by a missing solenoid plug on the black converter solenoid, see illustration.
The other possible cause for noise is a missing "O" ring between the black solenoid and the air management valve, see illustration.
A new solenoid, Part Number 17110655, has been released for service to repair this condition. Included with this solenoid will be two (2) "O" rings.
Procedure for replacement of black solenoid on (PEDES) Valve.
