The 07E9 error in a Ford vehicle is not considered a specific OBDII code. It indicates a system malfunction or in lay terms, points owners toward the source of an operating problem. 07E9 refers to the Ford's transmission control module. To identify areas of repair, an OBDII or similar scanner must be used to search for diagnostic failures within the transmission's powertrain. Failure of the transmission control module is often accompanied by slowed acceleration, the inability to shift gears and gear slippage. The TCM works closely with the transmission fluid temperature sensor, turbine speed sensor, and the throttle position sensor. If any one of these components fails, shifting will be compromised. The average cost to replace the TCM is $500-$900 in parts and labor, depending on make and model.
