Help, I went to adjust the voltage on my apps sensor, removed sensor and now there is no tag to go from. How do I adjust? I realize I shouldn't of done this... Thank you

do you have a live data tool to read TPS?    Since you have already pulled it off, all you can really do is put it back on and adjust until you get 0 % tps at idle. 

 

Where you trying to solve an issue? 

All I have is a voltage meter? Am I stuck buying a new one? 

Tons of forums out there. Figure I'd try to get truck to run perfect. I've never owned a cummins before. I have a smarty S02. It seems to help a bit but nothing crazy. I use truck for work so I don't need tons of power. I just want the truck to run good and efficient. I don't pull a trailer. I've done exhaust, intake, HX35 turbo and smarty tuner. Just seems as if my mileage isn't good and... when I'm on the throttle a bit then let off it seems to accelerate slightly split second before off the throttle. 

there is a lot of stuff out there on the forums that try to suggest trying to fix something that isn't broken.   

 

 

What do you consider not good mpg? 

 

What mods do you have? Lift? tires? gears?   What speed do you typically drive? 

 

You can try slapping it back on and adjust until the ovltage is less than .45v but it will be a crap shoot as to it working or not. 

 

 

What settings do you run the smarty on?  I have done a far bit of datalogging and I am really not a huge fan of the S03 smarty, sw3 was really the only level that worked well in my mind.  Depending on driving style higher levels would cause pretty poor mpg if you drive spiritied

Ok, 4" exhaust, intake, hx35 turbo (auto tranny), smarty tuner, 3:73 gears, 285/75r16 tires. No lift. Highway is prob 14-15L/100km (Canada). I carry a bit of tools and have a snowmobile deck on. Max weight in bed is approx 1000lbs. I bought truck used with 300,000km. It has a reman Bosch inj pump with a fass drp lift pump (replaced before I bought truck). I'm concerned injectors, or lift pump, or inj pump going. Oh and it's on stock tranny which slips slightly. I know it will need to be replaced soon enough. Thank for the help. 

are you sure your gears are 3.73?  that would be very strange unless someone did a gear swap. 

 

Honestly with a snowmobile on deck and 1000 lb 15/16 mpg ( 14l /100k) isn't bad.    Bigger tires is not helping, slipping trans is also not helping.  

 

Any codes? or any real reason to be worried about your injectors / pump etc?  The vp44 is really a lot tougher than most give credit for, our injectors are good to beyond 300,000 k on average. 

 

 

I would suggest you unload the smarty until you get the trans sorted.  Depending on how you have the smarty setup it can and will go right to full fueling right offidle, which is VERY tough on a trans and also very poor for mpg.  

Stock APPS sensor is safe at 0.4 to 0.5 volts.

 

Timbo APPS doesn't have a voltage setting it completely mechanical.

 

Wells APPS is safe at 0.5 to 0.6 volts.

 

The voltage adjustment is not for anything else but the idle validation switches. This has zero to do with transmission shifting, or lock up.

So the instructions I've followed in he past to see the voltage read by the APPS is to put a paper clip in pin #3 (green wire) and that will allow you to read the real time voltage, which the adjuster screw will change as you turn it. .65 volts at idle sounds right to me, but that is for a Timbo APPS, which may have a different idle voltage from an OEM one
