P274E Transmission Fluid Temperature Sensor C Circuit Intermittent

P274E stands for an unsteady sensor C signal: short interruptions or spikes that recover before a permanent low or high fault can mature. No manufacturer publishes this code or its debounce logic. Comparable intermittent coverage exists for the main sensor, where Ford's 2012 transmission strategy lists P0714 next to the open, short and in-range checks. Because the signal returns to normal, the warning may come and go, and the stored freeze frame is often the best clue: note temperature, speed and road condition when it appeared. A terminal with poor contact pressure, a harness rubbing on the case or moisture in the connector are typical; replacing the sensor without checking the wiring rarely helps.

Likely causes

Symptoms

• Intermittent warning lamp
• Temperature C drops out briefly on the scan tool

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
