I'm having a hard time with this ranger passing inspection due to check engine light. Code p0443 for evap purge valve. Command valve open with scan tool. Valve will buzz but not open. Connect test light to 2 wire pigtail and lights up. Install new valve and still dosen't open. Preform diognostic procedure checking resistance of all wires and shorts. All OK. Has power from fuse and PCM provides ground to open valve, but ground signal is too weak to open valve. Installed new PCM and checked all grounds. All OK. Still has P0443 and weak ground signal to valve. Has anyone else had a similar problem ?
