Well I just went to start the truck and the engine light popped up.

Now, I haven't reinstalled my tuner/dpf/doc delete since my trans was fixed (which was warrantied). It has driven fine, regen'd a couple of time per usual.

I'm right @ 30k miles, and i'm due for my 5k oil change and fuel filter changes. (which could explain the problem)


so the codes:

3 DTC's:


-P008C: Fuelcooler pump control circuit/open

-P008E: fuel cooler pump control ciruit/flow

-P040D EGRT sensor A circuit high.





main concern is that I have stuff i need to get done today, tomorrow, and monday... can i just clear the codes and be ok till monday afternoon? are these just "sensor" problems (in relation to EGRT code)? hopefully nothing severe. *no towing/hauling will be involved, just low key errands, etc.


tried searching a couple different ways and only the dtc code list appeared when i searched.


Thanks in advance.

P008C X Fuel Cooler Pump
Control Circuit / Open
This diagnostic will detect if the relay for the
fuel cooling pump has an open load error.

P008E X Fuel Cooler Pump
Control Circuit High
This diagnostic will detect if the relay for the fuel
cooling pump has shorted to positive voltage.

Sounds like your fuel cooler pump ***** the bed. you will be ok to run without it for awhile your main fan will kick on more often. Good to hear the tranny was on warrenty.

P040D X X X
Exhaust Gas Recirculation
Temperature Sensor
A Circuit High
This error occurs when the EGR cooler inlet sensor
temperature output value is lower (higher voltage
signal) than a minimum probable temperature,
indicating an open circuit or short to power.
N > 650 rpm
torque setpoint >53 N-m
ECT > 60 deg C
4.65v >5sec
Wiring, Tegr_IN sensor, PCM

You can see this one on the DD its probably reading 140*F all the time. So in short nothing major just drive till you got time to go down again.

P040D is fine to drive on, but you won't have full power. It'll get you around though. It's more than likely a sensor. Can't vouch for the other two codes.
