i get which the ground wire is but it says,

With the ground wire removed from the ECM, turn the key on and then manually ground the Purge valve control wire.

what dose that mean?

3. To check for a problem on the control circuit (if the solenoid tests okay and you have voltage to the solenoid) plug the solenoid back in and remove the control circuit (ground) wire from the ECM connector (If you're unsure how to do this, do not attempt). With the ground wire removed from the ECM, turn the key on and then manually ground the Purge valve control wire. The solenoid should click. If it does, then you know there is no problem with the control wire to the solenoid and there is a problem with the ECM purge solenoid driver circuit in the ECM. You'll need a new ECM. However if it doesn't click, then there must be an open in the wiring between the ECM and and the solenoid. You must find it and repair it.
They want you to remove that pin C20 from the connector so you can manually ground the solenoid, bypassing the computer. The idea is to isolate the problem to either the wiring (if the solenoid does not click) or the computer (if it does click).

right, you've established that the solenoid itself is working properly. Now you're trying to determine if the problem is in the wiring, or in the computer.

Yes thats right it works i think and i hope its a wire problem and not the PCM.

Update:

Hi all so ive been busy getting all the codes out ofthe dam computer, only have 2 codes over,
bettery temp sensor and the high voltage for the fuel gauge,i can live with that.

the p0443 code turned out to be giving that fault code because of the o2 sensor (bank 1) i had solved that problem buy calling my local auto parts dealer, as you all know i was srtapt for cash,
i told the guys at the shop i neede a o2 sensor for a jeep xj, they only had the universal o2 sensors, they dint have any in stock but they had a used one which was used to test a cat on an other car for €20,
i told them i will take it.
placed it in the car and what next yes the codes are gone no more po443, p0132 , p1685



so the next job was the fuel gauge and cluster, what a head ace that was.
Photos of what i had done











this photo the gauge cluster connector how it should be, i had to shorten the connector buy cutting away the last 2 pin holes to make room for the new fuel gauge otherwise i would not worked out, pin 5 and 6 are now moved to pin 8 , 9








all in done job took me 2 days to figure out the wires very

No more hesitation what so ever
It s amazing how many codes get thrown at you if just one o2 sensor is out of wack.
On the bright side it great just one sensor solved all the codes that are important.

Im a happy fellow, jeeps is running fine no problems as of yet.
I would like to know if i connect the the fule level sensor wire k226 DG/LB to the pc will that stop the Neede on the gauge from moving up and down when i turn a cornner?
Its a pain in the back Side prity anoying. I was searching on the web about how to solve this and according to this web they menstion that the computer helps to keep the gauge still

Quote: As for filtering, it is your thought that code running in the ECU takes, for example a reading per second from the sensor, averages them out over 10 seconds and then drives the gauge to represent this average?

http://www.jeepsunlimited.com/forums...pointers/page2


So my question is can / should i run the dark blue /light green wire from the fuel level sender unit from the tank to the pc and then back to the fuel gauge will that Work?
Also if it will Work then it might just solve the high voltage code p0463 im getting for the fule level sensor .

I think that would only work if you were using the stock XJ gauge. On the OBDII systems, there are a number of computer "modules" (engine control module, transmission control module, gauge cluster module, door module, security module, etc.) that communicate with each other via a coms bus (called the CCD Bus by Chrysler/Jeep). In the case of the stock XJ gauges, the senders all connect directly to the ECM. The sensor signals are used primarily to control the operation of the fuel injection and spark timing. The ECM also includes an abbreviated (filtered) digital version of those sensor signals on the CCD bus when it sends out its status. These filtered sensor signals are seen by the gauge cluster module, and the gauges are electrically actuated accordingly.

So, in summary, unless your gauge is using the CCD signal instead of the direct sensor signal, it will not make a difference.
