In the condition of electronic controlled acceleration system, APS Sensor is the only and the most important parts to reflect the will of driver. Especially, the non-reference type APS is the critical part of this system. It can`t provide the cross-reference values and it will make the vehicle goes into the `NMC(Non-moveable condition)` or `Limp-home mode` on the malfunction situation easier. If the situation is happened, it`s very dangerous condition for the drivers, soldiers and war material systems of battlefield. The electronic control is not a necessary system for the tactical vehicles. The tactical vehicles must be prepared the manual control system independently from the electronic control system to escape, save and rescue the soldier`s life and war materials. Therefore it was studied the water-penetrated broken APS output. If the output value was changed without driver`s will, even the cross-reference type APS, it will effect the uncontrollable engine RPM changing or the performance down on limp-home mode. It means the manual control system of tactical vehicle is needed for any kinds of APS.
