Yesterday I was driving around and the Check Engine light came on. It wasn't acting funny though it seemed sluggish. When I stopped and got back in to come home it was no longer on. I checked the codes and it is a 31 and the 62 I mentioned in a previous post.
I assume this means I need a new purge valve. Does anyone know different? Is there some test I should do. I'm looking in the FSM.
The Mopar purge valve on RA looks nothing like the one on my truck. The two other brands, more expensive do have the three tubes.
It was originally a CA vehicle.

Nothing in the FSM about fault codes from the PCM. The picture in the fsm looks like my purge solenoid.

 

31 Evap purge flow monitor failure or evap solenoid circuit

62 PCM failure SRI mile not stored

The 62 raises some eyebrows, but, it really isn't critical.

I don't know how the PCM monitors purge flow.... if it just looks for MAP to increase.... then its entirely possible the valve is just bad.

 

The 62 is weird. I thought I had removed it. I'm at 166Kish miles. This is a copy of the 95 fsm but its the same as the 94. For some reason I cannot copy direct from my 94 fsm which I bought in disk. The 95 that I downloaded from this site lets me copy from it? I think I might clean the EGR and see if it comes back. Could be I need to find a new canister that will work on this truck.
EVAP CANISTER PURGE SOLENOID
Vacuum for the EVAP canister is controlled by the
EVAP canister purge solenoid (Figs. 5 or 6). The solenoid
is operated by the powertrain control module
(PCM). The PCM regulates the solenoid by switching
the ground circuit on and off based on engine operating
conditions. When energized, the solenoid prevents
engine vacuum from reaching the EVAP canister.
When not energized, the solenoid allows vacuum to
flow through to the EVAP canister.
During warm-up and for a specified time period after
hot starts, the PCM grounds the EVAP canister
purge solenoid causing it to energize. This will prevent
engine vacuum from reaching the EVAP canister
valve. When the engine reaches an operating temperature
of approximately 27°C (80°F) and a time delay
interval of about 100 seconds has occurred, the PCM
removes the ground to solenoid. The de-energized solenoid
allows vacuum to flow to the EVAP canister
and purge fuel vapors through the intake manifold.
The EVAP canister purge solenoid will also be energized
during certain idle conditions in order to update
the fuel delivery calibration
