Re: OBD Code Definitions 1993 Trans Sport
I found a bunch of cracked and collapsed rubber lines that I will change out.
I found the Purge Valve Solenoid (I think)... kinda top center of engine. Is there a valve or any thing serviceable right on the Carbon (Vapor) Canister besides maybe a filter? I found these parts online: Vapor Canister https://www.thewrenchmonkey.ca/auto-...apor-canister/ Vapor Canister Filter https://www.thewrenchmonkey.ca/auto-...nister-filter/ Vapor Canister Purge Solenoid https://www.thewrenchmonkey.ca/auto-...urge-solenoid/ Vapor Canister Purge Valve https://www.thewrenchmonkey.ca/auto-...r-purge-valve/

Re: OBD Code Definitions 1993 Trans Sport
Here's a neat site I found. This thread discusses some of the same material in this thread.

Re: OBD Code Definitions 1993 Trans Sport
It is a hard copy manual...2 volumes.., about 2000 pages, that I had bought from GM when I bought the car. THe "user manual" contained the "order form" from GM. This is something that is no longer available in the digital world...
My website www.avigex.ca/xport contains a lot of scanned pages. It used to be fully open to all a few years ago but the heavy traffic (specially from Russia..and I feared contamination ) ended up busting the allowed traffic on my website so I provide specific links on request now... EDIT: exactly this one on ebay https://www.ebay.com/itm/1993-Pontia...k:2:tongue:f:0 ..and contrary to the description the seller gives, it covers both the 3.1 and the 3.8

I missed this reply so hense the late reply. The link to your site says 'forbidden'. How do I access is, or do I? 😊 I'm just getting around to this work now so I have to review the whole thread but that is fine.

Re: OBD Code Definitions 1993 Trans Sport
Yeah..as I stated in my previous post, "avigex.ca/xport" is not "open" access (for reasons I specified) ....just links for specific items like the one I gave for sensors..

Re: OBD Code Definitions 1993 Trans Sport
OK, I picked up some parts from the wreckers. I swapped out my original PROM into the wrecker ECM. On the road test the check engine light was going on and off for awhile. For awhile I thought we might have some positive results but after the engine warmed up it started to limp again, then I ran out of gas! I'm back at home now.
I think I remember that the EGR valve doesn't activate until the engine warms up. I'm going to swap it for the wrecker unit. Then I'm going swap the carbon canister and the purge valve. I'll report back in awhile. 😊

Re: OBD Code Definitions 1993 Trans Sport
*The original unit reads 2 coils around 50 ohms and 1 around 25 ohms. *The wrecker unit reads more like LPM said I should be finding; 2 coils around 25 ohms and 1 coil around 12 ohms. LPM, maybe I should use the wrecker unit but the other one is not that old??
Does anybody have that info? I am going to try all this stuff before I change out the canister with a wrecker unit I bought (This canister does not have a replaceable filter). I'm starting to wonder if it might be a bad wire or connection somewhere; I pray not.

Re: OBD Code Definitions 1993 Trans Sport
At some point in that era (maybe 1993, or 94-95) the canister purge solenoid went to a pulse width modulated (PWM) arrangement where the ECM would turn the solenoid on and off rapidly at part throttle, low load, to purge the EVAP canister. The solenoid is supplied by 12VDC and switched by the ECM. You can measure the resistance of the solenoid, and expect to read around 25-35Ω. You could also apply 12V to the solenoid and listen for the click when it moves.
As for the temperature sensor resistances, this table is still valid:

The purge valve (PWM design) reads around 37 or 38 ohms across the coil contacts at 70F. It's just above the high end of the spec range but is that good enough? The solenoid energizes (opening the port) using a 9 volt battery. The valve holds vacuum indefinitely, and opens up sufficiently. If the resistance is good enough being just over the high end it looks like the purge valve is usable?
