Code P0883 Jeep Description

The Transmission Control Output circuit is used to supply power to the Transmission Solenoid/TRS Assembly and to the Powertrain Control Module (PCM) when in normal operating mode. The purpose of the Transmission Output circuit is to allow the Transmission Control System to turn off the power to the Transmission Solenoid/TRS Assembly in the event that the transmission should need to be placed into "limp-in" mode due to a Diagnostic Trouble Code (DTC).
After a PCM reset, (ignition switch turned to the run position, or after cranking the engine) the Transmission Control System verifies that the Transmission Output circuit is open by checking for voltage on the Transmission Output circuits before the Transmission Control System requests for the circuit to be powered up. If voltage is detected on the Transmission Output circuits before the request is sent, the DTC will set.
This DTC is set if the PCM senses greater than 3.0 volts on the Transmission Control Relay Output circuits prior to a request from the PCM to energize the Transmission Output circuits.
