P0701Transmission Control System Range/Performance
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P0701 means the transmission control system works outside its expected range or its function is implausible – without a circuit fault. What exactly is checked is up to the manufacturer; no GM, Ford, Saab or bulletin document available to us describes the strategy. The only manufacturer evidence is Ford's engine module list for 6.8 L E- and F-Series trucks, where P0701 is stored without the check engine light. Typically the control cannot plausibly achieve the requested gear, pressure or torque, and the transmission goes into limp mode. Individual components have their own codes (P0705 ff range sensor, P0715 ff speed sensors, P0750 ff solenoids).
