ENGINE 5 Cam sensor Knock sensor 3 Cam sensor: The cam sensor is fitted on the timing gear cover front. The position sensor is a magnetic field sensitive transducer and generates a voltage output proportional to the rate of change of the magnetic field near a “sensed target” configuration. The cam sensor senses the position of the circular slot on the timing gear and gives you a feed back to the ECU. The synchronization of cam and crank sensor indicates 1st cylinder piston TDC. 4 Knock sensor (Accelerometer): The knock sensor is fitted on the cylinder head. The knock sensor is a mechanical vibration sensitive transducer that mounts to an engine and generates a voltage proportional to the mechanical vibration in a predetermined location. It senses the knocking in the cylinders during combustion.This sensor is used for Accelerometer strategy.It is a wide brand sensor gives high output and flat response.It has got robust and environmentally sealed integrated connectors. 5. Boost Pressure and Temperature Sensor (TMAP sensor): This sensors is fitted on pipe connecting intercooler to engine intake for measuring air flow pressure and temperature. This sensor gives the pressure and temperature of the air entering the engine after compressed by the turbocharger.Fuel quantity and injection timing are optimised based on these inputs T - Map sensors
