SENSOR STANDALONE DIAGNOSIS Use TATA diagnosis tool to check for : Signal voltage - > than 0.5V or < than 0.4V Switching frequency - > than 0.2 Hz Use multimeter to check the heater function by measuring the heater resistance. Heater resistance at room temperature - 90 ohms Supply voltage - 12V DC Check the signal voltage (Between pin number 2 and 3) Signal Voltage - 0.68 ± 0.25V DC- at idle position Signal Voltage - 04.25 ± 0.45V DC - at WOT position CAMSHAFT POSITION SENSOR III. COMPONENT DETAILS A typical Hall Effect Sensor has three wires or terminals: one for ground, one for supply or reference voltage and one for the output signal. To produce an output signal, a Hall Effect Sensor must be supplied with a reference voltage. When a metal/wheel passes through the air gap between the magnetic field (Magnet) and silicon chip (CAM sensor), it blocks the magnetic field and causes the chip’s output voltage to suddenly drop to zero else the chip’s output voltage is 4.7 Volts. COMPONENT LOCATION The cam phase sensor is mounted on cylinder head. 1. Intake Camshaft Sensor Petrol Engine Ph-2 (CAFÉ)_DCT 179
