Transmission Fluid Temperature Sensor B Circuit Range/Performance

Where it lives

For P2741, start at the sensor the description names.

Check these first

• A transmission fluid temperature sensor B reading outside its expected range
• High resistance in the transmission fluid temperature sensor B circuit
• A failed transmission fluid temperature sensor B
• A transmission fluid temperature sensor B that has drifted

What to do next

1. Read transmission fluid temperature sensor B on a scan tool
2. Compare transmission fluid temperature sensor B to a cold start reading
3. Test the transmission fluid temperature sensor B circuit for added resistance
4. Check the transmission fluid temperature sensor B connector pins
5. Replace transmission fluid temperature sensor B if the reading drifted
6. Clear the code and retest
