The automobile fault code U1119 indicates a problem with the Transmission Control Module (TCM) or its related wiring harness and connectors. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty TCM, an open or shorted TCM harness, or a poor electrical connection in the TCM circuit.

The repair importance is high as it affects the transmission system’s performance. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour. To fix the issue, one should visually inspect the wiring harness and connectors for any damage or corrosion and check for broken, bent, or pushed out connector pins.
