  P1140 Load sensing A "P1140 Load Sensing" diagnostic trouble code (DTC)  indicates an implausible signal from the engine's load sensing system . The exact meaning and cause can differ significantly depending on the vehicle's make and model.   The load-sensing system uses several sensors to measure the amount of work the engine is doing to help the powertrain control module (PCM) adjust the air-fuel mixture, ignition timing, and other functions for optimal performance. When the PCM detects an inconsistent or unexpected signal from these sensors, it can trigger the P1140 code.   Vehicle-specific meanings Porsche:  For some models, such as the Boxster, P1140 points specifically to an implausible load-sensing signal. Possible causes include issues with the cruise control operating cable, a faulty throttle position sensor (TPS), or vacuum/air leaks. Nissan:  For vehicles like the Pathfinder, P1140 can relate to the variable valve timing control (VTC) position ...
