Diagnostic code P1870 indicates a problem with the Transmission Fluid Temperature (TFT) sensor or the transmission control module (TCM) in vehicles. To repair this code, first, inspect the wiring and connectors related to the TFT sensor for any damage or corrosion. If the wiring is intact, test the TFT sensor for proper operation and replace it if necessary. If the issue persists, further diagnostics may be needed to evaluate the TCM and its programming.
