Ford Canister Purge Regulator Valve (CANP 9C915) Test Procedure - Figure 11

This document is a one-page service procedure describing how to test the Canister Purge Regulator Valve (part reference 9C915), a component of the evaporative emissions control system. Two test steps are given. First, with the valve de-energized, the technician applies 5 in-Hg of vacuum to the "vacuum source" port; a good valve should not pass air, and if it does, the valve must be replaced. Second, while applying 9 to 14 volts DC to the valve, the valve should open and pass air; if it does not, the valve should be replaced. The page includes Figure 11, a line drawing of the Canister Purge Regulator Valve showing three ports labeled CANISTER, CARB, and VACUUM SOURCE, with drawing reference number A9386-A. The document gives a reader the pass/fail criteria for bench-testing this solenoid-operated purge valve using only a hand vacuum pump and a DC voltage source. It was uploaded as part of an album of 1990 Ford Bronco emissions system documents, though the page itself does not state a specific vehicle year, model, or engine.
