P07E4 — Unable to Engage Park
The TCM commands the park pawl to engage but the position sensors do not confirm engagement — typical for shift-by-wire systems where the park actuator (motor or solenoid driving the pawl) is faulty, the cable is broken, or the pawl is jammed against a tooth and cannot drop in.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
