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.
Is it safe to drive with P07E4?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
