Transmission Fluid Temperature Sensor Circuit Range/Performance
The P2741 code indicates that the Transmission Control Module (TCM) has detected a signal from the Transmission Fluid Temperature (TFT) sensor that is outside the expected range or performance parameters. This sensor monitors the temperature of the transmission fluid to ensure proper shift scheduling and torque converter lockup. A faulty sensor, wiring issues, or low fluid level can cause this code.
01. Most Common Causes
- Faulty transmission fluid temperature sensor
- Damaged or corroded wiring/connectors to the TFT sensor
- Low or contaminated transmission fluid
- Internal transmission problems
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or overheating
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check TFT sensor wiring and connector for damage or corrosion.
Step 4: Test TFT sensor resistance with a multimeter and compare to manufacturer specs.
Step 5: If sensor and wiring are OK, check for internal transmission issues.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause transmission overheating and damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Typically $50-$150 for sensor replacement, but could be higher if wiring repairs or transmission service is needed.
