96 Bronco, 2" lift and 32 TA 2's, 351 with high flow cat and exhaust, other than that all stock except the stereo of course... She now has 226,000 miles
Just replace almost everything from the A/C radiator back to the block last summer, new timing chain and gears, alt., A/C everything except vacuum lines (taking her in for someone to do that), heavy duty fan clutch - that was a mistake, charcoal canister, battery cables... you get the gest. Was suppose to have a "friend" who is a motor guy help me and yes he was being paid but he was unreliable for showing up so I did 85% of the work myself, I'm not a motor guy. All done and she has taken me on 1/2 dozen hunting trips with no problems. But now I have P1443, P0402 and P1406 codes, I have spent hours researching what these are and the fixes. P1406 (DPFE sensor) no problem, P0402 (EGR) no problem, the P1443 (EVAP Control System Pruge Control Solenoid or Valve Fault) huge problem. I can not find anything on a 1996 5.8L as to what this thing looks like where it is or what it takes to fix it. If there is a test to determine if it's one part or both, or if I should replace both parts at the same time. Any suggestions as to where to find information on this and should I start with a particular repair and see if that will clear out the other codes. Please keep in mind I'm not a motor guy so if it involves a lot of technical stuff or jargon, I'm screwed. Biggest problem is I can't afford to take it to a shop to have this done and it has become my daily driver as the tranny went out on my Expedition.

Section 03-13: Evaporative Emissions
1996 F-150, F-250, F-350, F-Super Duty and Bronco Workshop Manual​
DESCRIPTION AND OPERATION
System Components

Fuel Tank Evaporative Emission System

The evaporative emission system limits the amount of fuel vapor a vehicle may release to the atmosphere, enabling the vehicle to meet current federal and state requirements for fuel evaporation.

The following are components of the evaporative emission system:

  • Sealed fuel tank (9002)
  • Fuel tank filler cap (9030)
  • Evaporative emission valve (9B593)
  • Evaporative emissions canister (EVAP canister) (9D653)
  • Evaporative emission canister valve (9B963) (some engines)
  • Evaporative emission canister purge valve (EVAP canister purge valve) (9C915) (some engines)
The system works by capturing a very high percentage of fuel vapors that might otherwise escape from the fuel tank. It then directs these vapors to the evaporative emissions canister where they are stored while the engine (6007) is not running. When the engine is running, and conditions are acceptable, the vapors are purged out of the evaporative emissions canister and into the engine. This clears the evaporative emissions canister and allows it to accept more fuel vapors the next time the engine is shut off.

The system is basically the same for all vehicle and engine tubes: a hose or tube runs from the fuel vapor valve at the top of the fuel tank to the evaporative emissions canister to allow fuel vapors to pass from the tank to the evaporative emissions canister. A evaporative emission return tube (9G271) runs from the evaporative emissions canister to the engine, allowing vapors to be purged from the evaporative emissions canister. Some engines use additional valves in one or more of these tubes to provide additional control over how much or when fuel vapor will be allowed to pass.


Engine Evaporative Emission System

This system consists of:

  • Evaporative emission canister valve (some vehicles)
  • Evaporative emissions canister
  • Solenoid vent valve and purge regulator valve (some vehicles)
  • Secondary air bypass valve (some vehicles)
  • Thermal vent valve (some vehicles)
Not all of these components are used on any one system, since usage depends on the calibration of the complete vehicle.

System control and operation are accomplished through five separate basic functions in the system:

  1. Fill control venting.
  1. Tank vapor venting and storage system.
  1. Fuel vapor return system.
  1. Fuel vapor purge system.
  1. Pressure and vacuum relief system (fuel tank filler cap and tank vent valve).

miesk5 Note,

The 96, Vapor Management Valve (VMV) replaces the canister purge valve (CanP valve) used in EEC IV. But the 96 manual still shows CanP valve probably because it was a late addition to the 96 production line.

As you know, The vapor management valve (VMV) replaced the canister purge valve used in EEC IV; it is located on passenger side firewall, high in our 96 5.0L

...
Overview; "...Non-enhanced evaporative systems use either a Canister Purge Solenoid or a Vapor Management Valve to control purge vapor. These systems are tested differently as described below.
The Vapor Management Valve (VMV) output circuit is checked for opens and shorts internally in the PCM by monitoring the status of the duty-cycled output driver. When the output driver is fully energized, or de-energized, the feedback circuit voltage should respond high or low accordingly (P0443). The VMV functional check uses the idle airflow correction for the IAC solenoid to check for adequate purge flow. The VMV is a source of engine airflow at idle, therefore, a change is VMV airflow will produce a corresponding change in IAC airflow. The IAC airflow correction is checked while the VMV is normally open (> 75%), then checked again after the VMV is commanded closed (0 %). If the difference in IAC airflow corrections is too small,
it indicates inadequate VMV flow (P1443)..." by Ford motorcraftservice.com

Ok, after cursing for 3 hours because of the character limit here, I missed posting this back in for P1443,
➡that will give you easy checks First,

EVAP Vacuum System, Purge or VMV Fault
Several conditions can cause this code to be set. A loose or broken gas cap, a damaged carbon canister, damaged or plugged fuel vapor hose, a damaged purge solenoid, or Vapor Management Valve (VMV) are all possible causes. A multimeter or scan tool can be used to test the components.

Leak Detection; "...There is actually a "smoke machine" for diagnosing leaks on cars. The shop I work for has a snap-on one. It is primarily used for checking for leaks in the evap (carbon canister) system on OBDII (1996+) vehicles, like the check gas cap light on new cars. It heats up a smoke solution that has flourescent dye in it, then shop air pressure regulated to about 1psi forces the smoke into the system. Where ever there is a leak the dye condenses out of the smoke and can be seen with a blacklight if you dont see obvious smoke. It has lots of adapters for vacuum hoses, tailpipes, throttle bodies, etc. I have used it to find vacuum and exhaust leaks before. You could probably call around to local shops or possibly a ford dealer and see if they would "smoke" your vacuum lines and show you what leaks for a decent price. Im not too sure of a way to smoke one yourself at home however..." by Tim at FSB

Wow, that's a lot of information! Thank you Miesk5.
As I indicated I'm not a motor head so I don't have a vacuum gauge, a smoke machine or other fancy tech tools. I pulled the cap off the VMV on the firewall and put my finger on the port, it provided suction however it did not affect the engine idle. I understand the engine should have shuddered. Should I presume anything from this? The evap canister is new and I see no cracks. None of the lines are clogged but I don't know about the DPFE, I understand it can be clogged, I need to pull it to try to blow air through it. As an FYI I'm using one of those FIX'd diagnostic tools for my code info.

Shaggy, the answer to your question is NO! Too many people have discovered so many of my get out of town spots that were isolated, now it's starting to feel like going to the mall and looking for parking...
