Hi there,

This code is for the transmission fluid temp sensor. This is inside the transmission and usually requires a scan tool for testing and the wiring should also be tested. Here are the details.

Trouble Code Conditions:
When 15 minutes or more have elapsed after engine is started, No. 2 ATF temperature sensor resistance is more than 156 kOhm. (4.915 V) for 0.5 seconds or more (1-trip detection logic)

Possible Causes: 

• Open in No. 2 ATF temperature sensor circuit

• Transmission wire (No. 2 ATF temperature sensor)

• ECM
