I know about the 2ndary O2, and the knock sensor, but has anybody found a way to trick the Evap purge solenoid on an OBD2 car? My evap canister has a bunch of dirt in it, and i wanna remove it for a wire tuck. Its just a soleniod so there has to be something.

yea I really REALLY wanna do OBD1, but cant due to budget,

But there has to be a resistor i can wire in there to trick the ECU like I did for the 2nd o2 sensor? its not a sensor its a solenoid, so its normally shut unless the solenoid is grounded, but how does it set teh CEL off if it reads "not enough flow"? Im sure if somebody knew, this would save ALOT of trouble for alot of people

find out if it needs suction or pressure, if it need's suction/vacum, hook it up to your intake, if it need's presure, find a source for that...

i dont think it's wise to remove it tho...

its mostly for emmissions, which i dont have here. and its only used durring startup. Plus im scared about all the dirt that came out of the canister (its currently installed now), but i really dont wanna risk sucking up a crap load of dirt into my IM.

Plus plugging the vac lines gives a more crisp throttle response.


You know about the intake thing, you might be a genious! But Im frickin trying to clean up the bay....maybe ill hook it up to my PCV valve.?


anybody have poor MPG with the EVAP removed?

well, if you can do it and it wont cause any problems go for it...

i was told by a friend that it could actually be dangerous to remove it due to exhaust gasses or some bullshit...

come to think of it, he prolly told me that cause he didnt want to help me with it... he's a mechanic so i belived him...

i may have gotton owend and didnt even know it... lol

the evap monitor uses the orvr valve, purge and vent valves. it opens and closes them and watches the fuel tank pressure sensor. I wouldnt want the task of rigging up something to mimic this.

If you can disable it at the pcm then fine. otherwise....

OBD1 conversion

You can have the gas fumes vent to the standard EVAP vent hose, that goes to a safe location....its the CEL im worried about.

how will u trick the monitor? if it fails you will get a cel, evap can throw cels for a variety of things. p1456 evap small leak ,p1457 evap big leak. you have no purge flow codes etc.... You cant's just rip it out and cap it off.

I did, the only cel I got was a 92. Again, i only have 1 sensor, and thats the Evap purge solenoid. ive ran it capped for a few weeks, and every 3 days i got CEL 92. thats the only thing i need to worry about. 96 coupes, and all 99+'s have the other sensors
