How many camshaft sensors does the Qashqai have?
1 Answers
The Qashqai has two camshaft sensors: one is the intake camshaft position sensor, and the other is the exhaust camshaft position sensor. The camshaft position sensor is a sensing device, also known as a synchronization signal sensor. It serves as a cylinder identification and positioning device, providing the ECU with camshaft position signals, which are the primary control signals for ignition. The methods for measuring the condition of the camshaft position sensor are as follows: 1. The camshaft sensor is generally a three-wire Hall sensor, with one wire being a 12V or 5V power line, one signal line, and one ground line. 2. Unplug the connector, turn the key to the second position, and use a voltmeter to confirm that the power line has voltage output. Use the meter to identify the ground line. With the voltage setting, connect one probe to the confirmed power line and the other probe to the remaining two lines. The line that shows voltage is the ground line, and the remaining one is the signal line. 3. At this point, turn off the key and disconnect the signal line, plug the connector back in, start the engine, and measure the signal line and ground line to see if there is a signal voltage. The output voltage should be less than the supply voltage. If no signal voltage is detected, the sensor is faulty.
