Where is the CMP sensor on a camshaft?
Disconnect the intake CMP sensor electrical connector and remove the retainer and the CMP sensor. Torque : 89 lb. In (10 Nm) Position aside the radio ignition interference capacitor. Disconnect the exhaust CMP sensor electrical connector and remove the retainer and the CMP sensor.
Where is the intake camshaft sensor located on a BMW E90?
Be sure to work with a cool engine. The intake camshaft sensor is located at the front of cylinder head on the left side (green arrow). The exhaust camshaft sensor is located at the front of cylinder head right side (yellow arrow) Using a scan tool, read fault codes to determine which camshaft sensor you have to test.
Where are the camshaft position sensors located on a car?
They are located on the rear of the cylinder head. There are two per cylinder bank, one intake, one exhaust, for a total of four sensors. I have included a factory description in the diagrams down below.
When to check a camshaft position fault code?
When you are dealing with camshaft position fault codes, be sure to test the sensor and confirm it is faulty. Other items could also set a camshaft position fault code, for example a dirty or defective VANOS solenoid. If you have a fault code for either camshaft position sensor, check the VANOS solenoid first.
What happens when the camshaft timing pin leaves the sensor head?
When the Camshaft Timing pin comes close to the sensor head, the voltage at the signal wire drops to zero. It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).
What’s the difference between the cam and the intake?
It makes no difference how you degree the cam in the engine, the lobe separation angle is ground into the cam. The intake centerline, on the other hand, is the position of the centerline, or peak lift point, of the intake lobe in relation to top dead center of the piston. This can be changed by “degreeing” the cam into the engine.
Where is the camshaft timing pin on a DTC p0340?
It is mounted at the end of the Intake Camshaft (See Fig. 2). When the Camshaft Timing pin comes close to the sensor head, the voltage at the signal wire drops to zero. It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).
How is the camshaft position sensor connected to the ECU?
The wiring harness should be routed away from the high-tension cable to prevent interference. This procedure will determine if the Camshaft Position Sensor is able to send signal to the ECU. This is done by measuring the voltage across the signal and ground wires of the sensor.
