Not sure what this code is meaning. Ive looked everywhere online and cant find anything, all im finding is loss of hydraulic pump prime. Im very clueless if someone could assist me id be grateful. Truck drives finex shifts gears fine no really issues i only code the check engine light on because my o2 sensors and catalytic converter are bad

 

So what is the code in the title if the only code you have is for o2 sensor and converter? At any rate, P0944:


The Loss of Prime Test is used to prevent transmission defaults and erroneous fault codes during temporary loss of pump prime that may occur with low transmission fluid under severe braking conditions, start-up, etc. and to point towards more subtle problems such as a plugged or ruptured oil filter. The Loss of Prime fault is set by a loss of hydraulic pressure in the transmission system. This condition, if sustained, will result in the vehicle being unable to move.


Possible causes being:


- Low transmission fluid level
- Shift Lever Position
- Plugged Transmission filter
- Faulty Transmission Oil Pump

 

The code read p0420 and p0430 i know what those are for. Then it gave me the code p0944
