What Does P0727 Code Mean?

OBD-II Code P0727 is defined as a Engine Speed Input Circuit no Signal

The Engine Speed Sensor tells the Transmission Control Module (TCM) how fast the engine is spinning so the correct gear can be engaged. When the TCM receives an inaccurate signal from this sensor, it can't properly shift the vehicle from gear to gear as the vehicle needs to change speed and rates of acceleration. Most vehicles use the crankshaft position sensor for this information. The engine control module (PCM) or TCM will set code P0727.
