94 Ranger with a DTC 332
I Have a 94 Ford Ranger with a 2.3L, manual Tarny 5 speed, 2 wheel drive.
Having problems isolating a DTC 332 code retrieved from Continues Memory which means Insufficient EGR Flow Detected from what i understand, unless someone else has a different description?. This issue started 2 years ago, and back then checked vacuum hoses and replaced a few. Then at that time replaced the Pressure Feedback EGR Sensor which did not resolve the DTC 332 so decided ignore the issue till now.
So just the other day decided to tackle this problem so, re-checked vacuum hoses, all okay. Vacuum is present and vacuum pressure appears good at the EGR Valve while engine running.
Checked the metal tube from the exhaust to the EGR Valve and no cracks or leaks that I can tell.
So checked EGR Valve for movement when vacuum is applied and it moves OK. Replaced the EGR Valve anyway because thought it may be sticking a bit during driving. Well that did not resolve the issue.
Checked resistance on the EVR Solenoid and that appeared OK at about 32 ohms. But figured maybe it too was sticking mechanically so replaced it anyway. That did not resolve the issue either.
Anyone out there that can shed light on this issue?? I am starting to think that I may have got a Bad PFE Sensor to begin with. All I have is a Haynes Repair Manual.
