this is a bit of a history lesson:
On early computer controlled engines the cam sensor was only really needed when the car started so the computer knew where the combustion cycle was. They ran a cross check with the crankshaft position sensor to insure the calibration was correct but complete failure would not cause serious trouble until the engine was shut off and a restart attempted.
Next level was when the manufacturers realised that if they measured the wear on camshaft drive components and or error in where the camshaft was timed they could make the engine run better and make less pollution.
Now with variable cam timing on multiple camshafts the computer measures the camshaft rotation to adjust the camshaft timing.
where are the camshaft position
check for the camshaft/crankshaft sensors... where is your camshaft/crankshaft sensors
On crankshaft position sensor, one camshaft position sensor.
The Crankshaft sensor and the Cam sensor monitor the position and or the speed of rotation of the crankshaft. Together they send signals to the ECM. The ECM uses that information along with info from other sensors to send spark and fuel to the cylinders at the correct time. Some engines only have only a crank sensor to perform that job. Other engines that have both crank and cam sensors that split the duties.
Nope. Rumor is crankshaft (near the bottom of engine) is only used for diagnostics, now camshaft sensors(s), are needed and are located near the top of the engine.
there is no timing belt sensor, only camshaft position sensors and crankshaft position sensor.
Answeron the rear of the engine, towards the transThe cam sensor is in the distributor.
poo17 is the powertrain control module uses the crankshaft position sensor and the camshaft position sensor information is to monitor the correlation between the crankshaft and the camshaft position sensors if the deviation exceeds a calibrated amount dtc poo17 will set see the dealer to have this updated
check the crankshaft and/or camshaft position sensors, if they are not working the ECU will not "see" the engine turning, therefore no need to spark..
It would bolt in, but will not run. The tone rings for the camshaft and crankshaft position sensors are different.
It does not have one. Crankshaft position sensors are used in distributorless ignition systems to tell the ignition control module where the crankshaft is in its rotation. The 1982 thru 1986 2.8L engines had distributors so they had no need of a crankshaft position sensor.
Check the idle, crankshaft and camshaft sensors.
