Q: What does code P2751 mean?

Intermediate Shaft Speed Sensor 'C' Circuit No Signal. P2751 means the transmission control module (TCM) is not receiving any signal from the intermediate shaft speed sensor 'C' circuit, so it cannot verify the actual speed of the intermediate shaft inside the transmission. The TCM sets this code when the sensor circuit stays silent while the vehicle is operating, which usually forces the transmission into a default shift strategy and may disable certain gear ranges.
