P275E
Transmission Fluid Temperature Sensor D Circuit Intermittent
The fourth transmission fluid temperature sensor signal jumps or drops out intermittently. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
