All right I just had my motor rebuilt and drove it for about 1000 miles without the edge juice or ez installed. Well I put them on today and almost immidetaly after putting them on I have the check engine light on and a P0243 and P0480 code. I know what they are something about low circuit voltage to fan 1 and solenoid malfunction or something. The truck runs awesome no problems at all. Will it hurt my truck to run it with these 2 codes or not. Also how can I fix these problems? Is it something to do with the edge boxes? Also everytime I clear them the come right back up as soon as I start the truck.

 

*P0243 Wastegate Pressure Control PWM
*P0480 Fan 1 Control Circuit

 

I know what they are just how should I fix it?

 

I just got these codes today on a cold start tonight. Looks like I need to do more searching.

 

Nobody kows a possible fix for P0243? P0480 doesn't seem to concern me but the wastegate does. If its under the powertrain warranty I have only 6k miles left so I better act fast.

 

I know why nobody knows how to fix it! Its because the code disapears after a day and a half. At least mine did.

 

I am getting the p480 and my engine is heating up!! It has never heated before. Where is this (low speed fan relay) I don't want to take to the dealer I am on vacation and pulling my toyhauler.

 

Check your Viscous Drive - If the fan assembly free-wheels without drag (the fan blades will revolve more than five turns when spun by hand), replace the fan drive. This spin test must be performed when the engine is cool.

If the VD is ok, it may be your Eng Coolant Temp Sensor near the thermostat housing (2 wires) or the thermostat itself (prob cheapest replacement part).

 

already replaced the ther tried turning the fan and it only turns about one fan blade NOT a complete turn

 

do you mean the fan clutch?

 

Yes, I did mean the clutch. How did the story end?

 

Thanks for the reply - Replaced the fan Clutch and that did the trick. Did find after alot of work and hitting my nuckles all the time is using a air chisle will brake the big nut loose in a couple seconds.
