Check voltage supply (T87) + and ground connection for sensor, signal wire to DME; check sensor installation; if OK, replace sensor

Engine Fault! Reduced Power

No remaining NWG is available to assume the role of master. At least one NWG is needed to calculate the engine's current position. If the last remaining NWG fails while the engine is running, it remains possible to calculate the engine's position using the KWG. Once the engine is off, it is not possible to restart it.
