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 shifting and prevent overheating. A faulty sensor, wiring issues, or low fluid level can cause this code.
1. Most Common Causes
- Faulty transmission fluid temperature sensor
- Damaged wiring or connector to the TFT sensor
- Low or contaminated transmission fluid
- Internal transmission failure
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping or overheating
- Reduced fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for additional codes and check freeze frame data.
Step 2: Inspect the TFT sensor wiring and connector for damage or corrosion.
Step 3: Test the TFT sensor resistance and compare to manufacturer specifications.
Step 4: Check transmission fluid level and condition; top off or replace if necessary.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can lead to transmission overheating and severe damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Typically between $50 and $150 for sensor replacement, but costs can vary if wiring repairs or fluid changes are needed.
