Checked for codes today as I have been once a week since I have boxes and have never had one before. Got these within the last week but the truck never so much as hiccuped...

P0073 Ambient Temperature Sensor High

P0107 Manifold Absolute Pressure Sensor Low

P0483 Cooling Fan Speed



Any ideas as to why? The only thing that I have noticed is my lift pump appears to be dying a slow death. Fuel pressure will hold steady between 8 & 9 lbs towing down the road. Then all the sudden it goes haywire! Up to 20 down to zero and then all over the place faster than you just read this. I thought the X-monitor was dying or at least the sensor but if I clutch the truck and let the engine come down to an idle it steadies at 7 to 9 lbs until I load the engine again. Towing pressures have been dropping to six alot lately. Never done that before either.

Scotty, I really need that pusher pump adapter BAD!!!

 

Check your air filter and the sensor cable that is attached to it.
Did yo just install your intake system
Did you start the truck with somthing disconnected
If you don't have a DRBII code reader then stop by you local Auto Zone and ask them to read the codes, after they are finished tey can reset them for you, that way you can see if they return.

 

Air filter is new and all connections are clean. The only changes to the truck in the last 10 or so days is the Edge EZ. I've had the C3.2 on for two or three months and never a problem until I added the EZ. This one has me baffled...

The top 2 codes are related to the intake sensor. I had the same problem when I started my truck with the sensor disconnected. The codes will clear after about 40 start/cool-down cycles. I can't help you on the last code. Good luck, Mike

 

When you added the EDGE EZ did you also install the elbow? I'll bet you also forgot to connect somthing back up when you started it the first time
I got codes when I installed my Six Gun because I too had somthing disconnected when I started the truck, turned the key to on or started. It will set codes because you compter is doing it's job.

 

one thing ya could do is clear them and run it and check again

 

I didn't install the elbow and nothing was disconnected. That's what has me concerned. I'm going to try to get the codes cleared this weekend and see if they crop up again...
