Laymans terms

This code means that the car's computer thinks the sensor that checks how hot or cold the transmission fluid is, isn't working right.

Explanation

The Transmission Fluid Temperature (TFT) sensor measures the temperature of the transmission fluid. This information is used by the vehicle's computer to adjust transmission operation for optimal performance.

Technical description

The P0711 code indicates a problem with the TFT sensor circuit. The sensor provides data to the Powertrain Control Module (PCM) to help manage transmission shifting and torque converter lock-up. A range/performance issue suggests that the sensor's readings are outside the expected range or inconsistent.

Symptoms

• Check Engine Light is on

• Transmission shifting issues

• Poor fuel economy

Common Causes

• Faulty Transmission Fluid Temperature Sensor

• Damaged wiring or connectors in the sensor circuit

• Transmission fluid level or condition issues

Glossary

Transmission: The system in a vehicle that transfers power from the engine to the wheels.

Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the TFT sensor and its wiring for damage.

• Check the transmission fluid level and condition.

Repair procedures

• Replace the Transmission Fluid Temperature Sensor.

• Repair or replace damaged wiring or connectors.

• Change the transmission fluid if necessary.

Tools required

• OBD-II Scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$150 - $300

Difficulty level

Moderate

Commonly affected vehicles

• Toyota Camry

• Ford F-150

• Service the transmission as per the manufacturer's schedule.

Error code type

Sensor Issue

User experience recommendations

• Do not ignore the Check Engine Light.

• Address transmission issues promptly to avoid further damage.

Warranty information

Check with your vehicle manufacturer for warranty coverage on transmission components.

Historical data

P0711 is a common code for vehicles with high mileage or those that have not had regular transmission maintenance.

Urgency level

Moderate – It should be addressed soon to prevent potential transmission damage.

Testing conditions

• Engine at operating temperature

• Vehicle in park or neutral

Component location

The Transmission Fluid Temperature Sensor is typically located inside the transmission or on the transmission housing.

FAQs

Q: Can I drive with a P0711 code?
A: It's not recommended to drive for long periods with this code, as it can lead to transmission damage.

Q: How often should I check my transmission fluid?
A: It's good practice to check your transmission fluid at least once a month.
