CAMSHAFT POSITION SENSOR—PCM INPUT DESCRIPTION The camshaft position sensor attaches to the rear of the cylinder head. The cam (red) is rotated by a shaft (gray) powered by a belt linked to the crankshaft (not shown). "The crankshaft position sensor was deleted for 2001 and 2002 models; engine speed, crankshaft position, and injection timing information will be derived from the camshaft position sensor signal. The PCM uses the Camshaft Position Sensor to tell it when the Crankshaft Sensor signal is correct, when a given Crankshaft Position Sensor signal is timed to Cylinder #1 for timing, and it is also used for fuel injector synchronization / start of injection. 60-2 magnetic crank, hall sync (crank offset is different than previous generation) M52 (single vanos) 60-2 hall crank, frequency inductive sync. Crank is by the crank, camshaft is by the crank. 7L v8? the truck wont start & all other issues are ok there is fuel & power , the spark plugs have spark, the injectors are not opening, I heard that between the camshaft position sensor & the crankshaft position sensor are my best choice to replace for my problem, can that. That is the amount of difference compared to new that you can see using an oscilloscope on the cam and crank sensor signals. Page 59: Accessory Drive Seal - Removal. The camshaft position (CMP) sensor supplies a 50-percent duty-cycle signal from the camshaft to the PCM to indicate the stroke (intake or exhaust) for any given cylinder. 25″ trigger wheels. "Monitors") The basic difference between a CMP and CKP(96+) is the number of pulses generated, per revolution. Also of note, even if the cam magnet was off a touch is shouldn't make a giant difference in how the car runs. You can also disable the cam sensor in the Custom settings as a test, if you determine it to be the cam sensor causing the issue, instead of the crank sensor. P0016 Meaning The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. There are two, one for the intake cam, and one for the exhaust cam. But there’s a big difference between the two as they perform different functions in the vehicle and have different symptoms when something goes wrong with them. The ecm stores this valve as ”vvt learned value” (when the difference between the target valve timing and the actual valve timing is 5 or less, the ecm learns it). The task of the camshaft sensor is to work with the crankshaft sensor to define the exact position of the crankshaft drive. Relationship between the exact time a plug is fired and the position of the piston in terms of degrees of the crankshaft rotation. But it isn't covered under the powertrain warranty. So for camshaft position sensing, a Hall sensor is typically better than a VR sensor, as it produces a full strength signal at low speeds, unlike a VR sensor. The computer uses the camshaft sensor to determine crankshaft position but uses the crank position sensor for all the ignition timing and exactly when to fire the injectors. I replaced the crankshaft postion sensor (crank sensor) after the check engine light came on, reset the ECU, turned the light off. 2001-’05 Escape/Tribute. trying to fix something you might not need to. Crankshaft – Camshaft Position Sensors serve essentially the same purpose as the ignition pickup and trigger wheel in an electronic distributor.
