Detailed Description

Walker 256-1107 is engineered to restore proper oil pressure signal function in vehicles that rely on an engine-mounted pressure switch for warning light or ECU input. When oil pressure falls, the switch activates the circuit to alert the driver or control system, helping reduce the risk of internal engine damage from low lubrication.
