P0711: Transmission Fluid Temperature Sensor "A" Circuit Range/Performance

P0711 means Transmission Fluid Temperature Sensor "A" Circuit Range/Performance. The transmission fluid temperature sensor helps the transmission control module adjust shift timing and torque converter lock-up. The signal is inside its electrical limits, but it does not make sense compared with what the module expects from other sensors or from engine conditions (a "range/performance" fault). The part is often working electrically but reporting a wrong or implausible value.

Can I keep driving? Drivable with care. Diagnose soon: performance, economy or other components can be affected.

Common symptoms

  • Check engine light on
  • Harsh, delayed or erratic shifts
  • Limp mode
  • Possibly incorrect gear display or speedometer issues

Possible causes

  • Failed sensor
  • Wiring or connector fault (check the transmission connector for fluid)
  • Low or contaminated transmission fluid
  • Misadjusted range sensor or shift linkage (range sensor codes)

How to diagnose P0711

  1. Check fluid level and condition.
  2. Inspect the transmission connector and wiring.
  3. Check the sensor signal on a scan tool.
  4. For range sensor codes, check the gear display matches the selector in each position.

Generic codes have the same definition on every OBD-II vehicle (petrol cars from model year 1996 in the US, 2001 in the EU; diesels later). Manufacturers can add their own enhanced codes; those are not listed here.

General guidance only. Fault codes describe what the engine computer saw, not which part failed: confirm with testing before replacing parts, and follow the vehicle's service information.
