Laymans terms

Your car's computer thinks the temperature sensor for the transmission is not working properly because it's reading too low. It's like when a thermometer says it's freezing when it's actually warm outside.

Explanation

The Transmission Control Module (TCM) monitors the temperature sensor circuit. If it detects a voltage signal that is too low, it sets the P1711 code.

Technical description

The P1711 code indicates that the Transmission Control Module (TCM) has detected a low voltage signal from the transmission temperature sensor circuit. This sensor is responsible for measuring the temperature of the transmission fluid, which is crucial for optimal transmission performance and longevity.

Symptoms

• Check Engine Light is on

• Transmission may shift harshly or erratically

• Poor fuel economy

Common Causes

• Faulty transmission temperature sensor

• Wiring issues such as shorts or open circuits

• Faulty TCM

Diagnosis steps

• Use an OBD-II scanner to confirm the P1711 code.

• Inspect the transmission temperature sensor and wiring for damage.

• Test the sensor's resistance and compare it to specifications.

Repair procedures

• Replace the faulty transmission temperature sensor.

• Repair or replace damaged wiring or connectors.

• Replace the TCM if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Error code type

Sensor Issue

User experience recommendations

• Do not ignore the Check Engine Light.

• Have the vehicle inspected by a professional if unsure.

• Avoid driving aggressively until the issue is resolved.

Warranty information

Check if the vehicle's powertrain warranty covers sensor issues.

Historical data

The P1711 code has been associated with sensor failures and wiring issues in older vehicles.

Urgency level

Moderate – It should be addressed soon to prevent further transmission issues.

Testing conditions

• Engine at operating temperature

• Vehicle parked on a level surface

Component location

The transmission temperature sensor is typically located on or near the transmission housing.

FAQs

Q: Can I drive with a P1711 code?
A: It's possible, but not recommended as it may lead to further transmission damage.

Q: How do I reset the P1711 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
