If it was me I would reset the codes and take for another spin and recheck and see if they come back...

both codes are independent of each other... 500 is from wheel spin237 is from low voltage at the map sensor

Here is the NAPA replacement... I highly suggest you get the Geno's for the cheaper price...

Do a MSDS look up through WalMart to get the information then it should list who produces the products. http://msds.walmartstores.com/

The coldest I've gone down to was -20*F... I think beyond that you pushing your luck... Even by Chevron's standards my fuel should of been a solid brick in the tank. I don't suggest doing this unless you got a back up plan... In my neck of the woods this is a very dangerous thing to do without a fall back plan. No cell service and some roads get little to no traffic...

As far as the research I did on the Super tech it uses the very same PPD chemicals as normal #2 diesel which was a shocker for me... Like you I don't put my full trust in it but I know it got to make a effect how much... I don't know! ADDON: After searching the web rapidly and reading a few pages from different companies you'll find all petroleum base oils (engine, gear, 2 cycle etc) all have to have a PPD added to allow it to perform in cold weather. It the synthetic oil that don't require on because of the simple point they are not produced from a petroleum base (no wax).

Buy a cheap inverter to plug the laptop into... Problem fixed... Or Sell me the software and cord... Problem fixed...

Totally understand why VP44 are at least $1,000.00 a pop. If you look at the money put down to pay for the test bench. Wow! But this where I grey area start for me... I would love like hell to get a copy of the VP44 rebuild manual so I can understand more about the VP44 pump.

Wow! Those rotors are ugly... Heck I might have to shoot a pic of mine...

SuperTech actually is PennzOil and no its not synthetic... Just good ol' fashion petroluem oil. Now going back a few year and remembering the stuff I did research on back in 2006-2007. As for SuperTech Unversial 2 Cycle Oil it has a pour point of -40*F. Normal winterized diesel at least here in Idaho has a pour point of -20*F. The the reason why synthetic 2 cycle shouldn't be use is because since all synthetic oil hav no parafin base oil in it... It had no reason to use a pour point depressant (PPD) which all petroluem oil must have to keep them from gelling. As for the effect 2 cycle oil has on fuel it not very clear as for gelling. But this is the way I look at it... If you got a jar of water you know the water is going to freeze at 32*F. Now take a jar of salt water you know the freeze point of salt water is below that of normal water. But it depends on how much salt is in the salt water. Now mix the salt water and normal water together and you know the salt water will have effect but how much is unknown. Now with that said replace water with diesel fuel and salt water with 2 cycle oil and you'll now understand my thoughts and theory of 2 cycle oil in the winter time. So if normal diesel is -20*F for a pour point and 2 cycle oil is -40*F surely it got to have a effect..

Only time your looking down the road of a mechanical failure is typically the P0216 code where the advancement cam is stuck in full retard. But P0215, P0251, P0252, P0253, P0254, P1688, P1689 are all electronic failures... But here is the $150,000.00 test bench for calibrating the VP44...

There has been such a huge scare about fuel being in the cab for years now and how you need to use a isolator... Diesel fuel needs to be heated to at least 150*F before it will ignite with open flame. The needle valve is a perfect choice for fuel hammer (water hammer) reduction. Because it allows you to reduce the pulse by closing till you get a smooth swing of the needle. Then if you do have a leak you can just shut the needle valve off. With a snubber it will keep the fuel hammer from occuring but now you can't turn off the fuel is there is a leak.

I think its GuessWho that has a Laptop OBDII reader too...

Nothing against you WhiteLightning... But that right there is what kills most transmission in the diesel realm this includes Fords and Chevy's... I watch hours of videos where transmission shops shake there head at the owners putting over sized tires on to correct a gear ratio problem (usually 4.11:1 ratio) and what happen is it increases the ability to hold torque (no slippage of the tires). So the the next weak point will be the transmission. Majority of all transmission failure is cause from oversize tires being added. Like now with my truck its really easy to spin the tires that great that mean less damage to the trans and clutch for me... Now another one to look at. Take your stock tire and weigh it. Now take a a oversize tire and weigh it. You'll find like I did going from 265/75 R16 to 235/85 R16 I lost over 20 pounds of rotational mass from each tire for a total of 80 pounds reduction gaining MPG's of about 1-2 MPG. Now take your taller tire and look at the amount of torque it will require to twist it. Place a tire/rim on the ground standing up and shaft in the middle (no crank). Now try twisting the shaft with you bare hands. Now take a small tire and do the same thing and you'll find the smaller tire requires way less effort to move. Really if you want to correct the ratio problem correctly I would change gears out of the diffs... But really 4.10 gears should be excellent for towing. CajFlynn is running 3.73 gears and got the best of both worlds towing those massive boats... Much heavier that a normal travel trailer...

Like we got a nother test of 2 cycle oil at 1280:1 ratio and after re-doing the math it turns out that 128:1 ratio it roughly 50 HFRR score some I'm tickled to death with 2 cycle oil.

What I've found on a few the sock of the heater or the actual plug build up some oxidation and get a hot spot that will burn the cord. So like mine would make the plug so warm the plastic was doughy. So I pull the pull and took some light sand paper and clean the pins of the plug and hooked it back up and it nice and cool. As for the Geno's Heaters jump on them! That a excellent price. Being the last time I bought a heat element for a Dodge at NAPA was ~$120 excluding the cord...

Electronics have a few thing... [*]RPM Tone ring [*]Fuel Solenoid [*]Timing Solenoid Once again I'm not 100% sure of this but like several articles about people removing the electronics to repair a blown chip inside by soldiering in a new one. But if change the electronics you had to re-calibrate it for TDC, and the 2 solenoids so the pump behaved properly. I think mechanically they are all the same inside but once again ont 100% sure... Man how I wish I could get my hand on a Bosch VP44 rebuild book.

Like ISX would say, "You don't count!"

Correct...

Right on... Adding to the diesel family... Gotta see pics...

Pull the knee bolster out and the switch is right there near the pedal arm...

When CajFlynn clears 900K+ miles on normal petroleum oil it makes you wonder...

Well that won't work from what I know of this subject... When the electronics fail and get replaced that's when you get into trouble. Because now you got to calibrate the eletronics to the mechanical part hence getting the right key for the shaft...

You stole my water jug out of the back of my truck...
