Throttle Position Sensor on a Diesel truck

Yep.

2 factory lift pump's then an upgraded Aftermarket lift pump. I ran pre and post filter fuel PSI sensors.

"The VP44 killer is low pressure from the lift pump"!

The sensor "TPS" is not hard to replace and calibrate!

Never lost the VP44 in 270K miles! Before upgrading to my 2015 6.7 HO.
