8 codes and rough running. Armchair diagnosis required!
 

P0237 Turbocharger Boost Pressure Sensor Low
P0193 Fuel Rail Pressure Sensor High
P2269 Water in fuel condition
P0340 Camshaft position sensor circut
P0341 camshaft Position Sensor Performance / Rationality
P2127 Pedal Validation Switch 2 Low
P2121 Pedal Position Sensor 1 Performance / Rationality
P0652 Sensor Reference Voltage 2 Circuit Low

Those are the codes that came up by cycling the key 3 times. Now for a great description of what my truck sounded like! LOL

-Sounded like an injector knock. Maybe only on one cylinder.
-Did this twice out of last 30 or so starts. Right after start up while engine was warm.
-Real touchy fuel pedal.
-Shut down engine and re-started. Both times it was hard to start.
-After turning engine on and off a few times everything was back to normal.
-I have an edge juice with attitude with the hot program installed. Did this on level 4 and stock.
-I will be yanking the juice with attitude off soon and have ordered a smarty jr. See what codes come up then.
-Will also be cleaning the battery posts and checking grounds.
-Water in fuel light never came on, and everything looked great when I took a sample off the fuel filter drain????
-205,000 kms so no warranty anyways.

What do you figure?

Thanks.

You may have a shorted wire going to the HIGH/LOW pressure switch on the A/C. That wire provides the 5 Volts to the camshaft sensor. Pics are in the thread on where to look at by A/C compressor.

I read that post about 3 months ago! Totally forgot about it. Sounds like it might be my fix! Thanks a bunch.
