Hey guys hopefully you can help me with this one. I'm returning to Toronto on Monday and I'm suppose to be bringing back the jeep. Its 5 and a half hours away.

Done 1 day prior to problem, I used sea foam(1/3 TB 1/3 Fuel tank). Done the day of the problem, I changed my oil and did a coolant flush. After the coolant flush I also sprayed my engine bay with water (dumb I know) I was trying to wash off some of the over spray.

So after 10-15 minutes of driving with no problems I suddenly got the check engine light I was away from home so I still had to drive the jeep. Then after another 30-1 hour of driving the jeep starting to sputter(hesitate) When holding the pedal a steady 2000 RPM it would start to jump (1500-2000 RPM). Day after it also stalled while returning from the mechanic with the codes.

Ok so now that that's out of the way here are the codes I got:

-P1491 Rad Fan Control Relay Circuit An open or shorted condition detected in the radiator fan control relay control circuit. This includes PWM solid state relays.

-P0645 A/C Clutch Relay Circuit An open or shorted condition detected in the A/C clutch relay control circuit.

-P0443 (M) Evap Purge Solenoid Circuit An open or shorted condition detected in the EVAP purge solenoid control circuit.

-P0700 EATX Controller DTC Present This SBEC III or JTEC DTC indicates that the EATX or Asin controller has an active fault and has illuminated the MIL via a CCD (EATX) or SCI (Aisin) message. The specific fault must be acquired from the EATX via CCD or from the Aisin via ISO-9141.

Also my number 10(Named starting system) fuse inside the cab is burning out and my day time running lights are not working.

I know just a cluster f*** of stuff.

Oddly enough I don't see how these could cause the problems. My jeep does seem to be running rich and blowing out liquids. The jeep only seems to have problems when I drive it and warms up.

So could this be because of my o2 sensors? Coil pack? TPS sensor? I don't knowww!! PLEASE PLEASE XJ GURUS HELP ME!

 

Oh my...it's late I'm sacking out.

-P0700 EATX Controller DTC Present This SBEC III or JTEC DTC indicates that the EATX or Asin controller has an active fault and has illuminated the MIL via a CCD (EATX) or SCI (Aisin) message. The specific fault must be acquired from the EATX via CCD or from the Aisin via ISO-9141.

"AW4" is Asin Warner, 4 speed. I smart guy here is always warning us not to squirt the TPS on the TB there. It scenes throttle position and has a trans side. Might account for your code and hesitating....Maybe stick a new TPS on there and save that one....make sure the dizy is dry, inside and out, go from there. Drive it!

 

Ok ill give that a shot tomorrow thank you sir!

Edit: Is it possible to clean/test the original? I hear these things aren't cheap.

 

Fixed it by cleaning all the plug and changing my upstream and downstream o2 sensors.

 

I don't see the relationship of these codes to your oxygen sensors. See if they come back which I think they might and if so, which ones.
