Hey everyone have an update.
Codes from PCM:
-0463 Fuel Level Sensor A Circuit High Input
-1693 Problem On The Network (companion)
Codes from ECM:
-0122 APPS Sensor Signal Voltage Too Low
-0123 APPS Sensor Signal Voltage Too High
-0216 Injection Timing Control Circuit Malfunction
On the 0216, the injection pump & lift pump are both brand new.
I also was getting the APPS codes from the PCM before, now there not appearing?
Here's where the fun begins!
I got the stock TPS back and installed, of course after reconnecting batteries the next day alarm was going off! Here are my findings. My tag reads 0.525 so I ended up setting it at 0.50. My initial test drive was same results (horrible) but after a short stop I got back in the truck and it ran like it was brand new.
I disconnected batteries again and redid the APPS calibration procedure. Truck ran awful again so decided to check voltage on TPS again without removing anything from the truck. It was reading 0.52 while idling so I adjusted back down to .50 and still gained 0.05 bringing it well over the recommended tag setting over 20 mins of idling and flicking to WOT. Something odd I also found if you barely pressed I would occasionally get a -0.02 drop right off of idle. Finally when slowly pressing the motor wouldn't start to rise till 0.64.
Its seems to me to be a faulty TPS, time for timbo?! Also, after doing some research a lot of people in other posts had a similar problem and where recommended to search for grounds but they never did a follow up saying if they where successful or not, if weather permits should I check them tomorrow? If so, is there any main ones that are known to go bad on these trucks?
I truly do appreciate all your guys help,
ready to get onto the fun parts of building a diesel up and not these gremlins. Starting to think I should have kept my 12 valve!
