P2803
Transmission Range Sensor "B" Circuit High
DTC P2803, sometimes indicated as P280300 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing transmission range sensor "b" circuit high.
This code is caused by a problem with the transmission range sensor "B" circuit. The most common cause of this problem is a bad sensor, but it can also be caused by a bad wiring connection, a bad ground, or a problem with the PCM.
The first thing you should do is check the wiring and connectors for the sensor. If there is any damage or corrosion, clean or replace the wiring and connectors. Then check the ground connection for the sensor. If the ground is good, test the PCM for problems. If the PCM is good, replace the transmission range sensor.

My service transmission warning and check engine light keep coming on with code P2803. Spoke with the mechanic and he stated this is an ongoing issue and should have a recall issued for it as it is an ongoing issue with Jeep Cherokees. This has happened several times. I purchased the vehicle 7/23/2019. Code and light cam on the first time 8/27/2019 and was cleared then it came on again 9/19/209, was cleared that morning and came back on that afternoon.

P2803 & P2800 sensors..Both sensors are defective and the cost to repair is far above fair pricing. Hydraulic control approx cost to repair 4100.00 dollars. This is ununfair repair costs. This vehicle has been maintained with above average care and has not been misused. Checking web site have found that this is not an uncommon problem with this model. Public should be warned about this defect in this model and a possible recall should me made.
