P Pump? I thought we were talking about a standard 01 VP truck. You have not said otherwise. But if it still has the same APPS bell crank and sensor on the block for a 98.5 to 02 what I said still applies. The sensor output ill not drop below idle of .5 volts if is properly adjusted on back with the loosened screws. That is the built in electronically stop point for voltage regardless of what the crank is doing. Idle and idle validation signals can't drop below that .5XX setting. Now above that when throttle is applied, slop at that point could very well jump around.
If it is the standard crank and apps it sounds like someone has installed a sensor at the bottom of its rotation and then tried to adjust the idle voltage with the stop screw on the bell crank. This is not the correct way to adjust the apps idle voltage. The screw is just to adjust cable slack before taking up acceleration.
So what exactly is your setup. Pump? APPS year, brand APPS.
Pictures? Is the culprit bearing a ball bearing or bushing?
We are talking about my 01. I understand it all applies thats why I mentioned the ppump having similar problems. If ppump bell cranks can wear, why couldn't a vp44 do the same if they are so similar. No one tried to adjust the apps with the set screw ever not once.
I adjusted it right properly. Back to .503 because prior to that it would fall under volt and set off a check engine light giving me a dead pedal . Its the ball bearing being the shaft in front of the apps. Im not going to dismantle my truck in the rain for a picture. I know whats wrongs with it Im telling you the bearing is worn and has play in it sending my sensor reading askew. There is no doubt about it.
I asked about a replacement bearing and you seem to be hung up on the fact if my bearing went bad. It did there isnt a question about if it did or didnt.
Do you have or know of a part number to replace the bearing on the shaft in the bell crank?
