What Does P1711 Mean?
The transmission fluid temperature sensor signal is outside the expected range during self-test procedures. The sensor reading is either too high, too low, or not changing appropriately during the test cycle.
Common Causes
40%
Faulty transmission fluid temperature sensor
30%
Damaged wiring or corroded connector at temperature sensor
20%
Short or open circuit in sensor signal or ground wires
7%
Failed transmission control module reading incorrect sensor values
3%
Transmission fluid extremely low causing sensor exposure to air
Diagnostic Steps
1
Step 1: Monitor transmission fluid temperature sensor reading in live data and compare to actual fluid temperature
2
Step 2: Disconnect temperature sensor and measure resistance across sensor terminals at various temperatures
3
Step 3: Check sensor signal voltage at control module connector with sensor connected and disconnected
4
Step 4: Inspect sensor connector and wiring for oil contamination, corrosion, or damage
5
Step 5: Verify ground circuit continuity and check for voltage drop on sensor ground wire
Estimated Repair Cost
$120 - $450
Parts + labor, varies by vehicle and location
The transmission fluid temperature sensor signal is outside the expected range during self-test procedures. The sensor reading is either too high, too low, or not changing appropriately during the test cycle.
The most common cause of P1711 (Transmission Fluid Temperature Sensor Circuit out of Self Test Range) is: Faulty transmission fluid temperature sensor
Typical repair costs for P1711 range from $120 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission may not shift properly when cold or hot. Control module may prevent shifting or use default values that cause harsh shifts or reduced performance.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1711 to identify the root cause.
