SOURCE: camshaft position sensor location

crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.

The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.

Crank sensors in engines are usually comprised of magnets and an inductive coil. They are principally based on the Hall effect. Common mounting locations include the main crank pulley, the flywheel, or occasionally on the crankshaft itself.

Some engines, such as GM's Premium V family utilise crank position sensors which read a reluctor ring integral to the Harmonic Balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

SOURCE: P0340 Code Camshaft Position Sensor


The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No. 1 is on its compression stroke. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors.

On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single "vane" spinning around by virture of a synchronized shaft which is driven by the camshaft. 

The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

change the crankshaft positon sensor in the rear of the engine above the oilfilter. Also check the wiring to this sensor, they have a problem shorting out. You have to change the camshaft and crankshaft sensors at the same time. Make sure you give your car a major tune up. Did you check yor starter?.........runjoe

SOURCE: camshaft position sensor

This V-6 has a very hard to find/hard to reach CKP - it is directly under the Distributor, about 4 inches below, inwards toward the Transaxle "bell". Almost dead-center in the back of the engine.
Your going to have to take the Air Filter and the air manifold that runs to the engine off. After that, take off the horn assembly to gain very, very limited access to wedge an extended ratchet into the bowels of the engine. 
I think the same socket that undid the horn assembly fit the CKP nut. It takes 10 minutes to undo the bolt a couple ratchet clicks at a time, at least 15 to get the thing to wiggle out, probably 15 minutes to unconnect, reconnect, and snap back to the fram the wire harness, and at least another 10 minutes to ratchet the bolt back in click by click.

Now you know why they say shops charge $500 in to do this - I think they must take the entire engine out... Very painstaking job that requires patience and precision... but quite satisfying to finish it yourself. 

Good luck and hope this helps,

SOURCE: need help finding camshaft position sensor

2.0L 2.4L Removal The camshaft position sensor is mounted to the rear of the cylinder head.

Remove the negative battery cable. Disconnect the PCV hose and reposition Disconnect electrical connectors from the camshaft position sensor. Remove camshaft position sensor mounting screws. Remove sensor.Loosen screw attaching target magnet to rear of camshaft and remove magnet.
Instalation The target magnet has locating dowels that fit into machined locating holes in the end of the camshaft.
- Install target magnet in end of camshaft. Tighten mounting screw to 3 Nm (30 in. lbs.) torque. Over torqueing could cause cracks in magnet. If magnet cracks replace it.
- Install camshaft position sensor. Tighten sensor mounting screws to 12.9 Nm (115 in. lbs.) torque.
- Carefully attach electrical connector to camshaft position sensor. Installation at an angle may damage the sensor pins. - Connect the PCV Valve hose. - Connect the negative battery cable.
2.7L V6 Removal
The camshaft position sensor is mounted in the front of the head.

Disconnect electrical connector from sensor. Remove camshaft position sensor screw.
CAM Sensor Location 2.7L
Without pulling on the connector, pull the sensor out of the chain case cover.

Installation - Install sensor in the chain case cover and push sensor in until contact is made with the boss on the head. While holding the sensor in this position,install and tighten the retaining bolt to 12 Nm (105 in. lbs.) torque.
- Attach electrical connector to sensor.

Good luck and hope this helps

06 bmw 525i codes p0174, p0171, p1338, p0340, p0365, and p1315


codes p 0171 and 174 refer ti system too lean
codes p 0338,340,365 refers to crank. and can shaft position sensors
code p1338 again is camshaft position sensor
code p1315 again is camshaft position sensor
too lean can be from fuel pump pressure too low
and position sensors can be wiring , connections sensors.
Involved in all these , one of the possible causes is the ECM
IF it is possible get a serviceable replacement ECM unit and substitute it first as there is no point in replacing all the rest if the ECM is faulty
could be water in the connections , corrosion etc
it is always suspect when so many different codes suddenly appear at the same time

My 1997 Mitsubishi Eclipse wont pass emissions because trouble code P1390. I dont know what this means? Ive researched it everyway I know? My check engine light wont come on at all? Help anyone? Thanks!


This is the direct definition of this code
Mitsubishi DTC P1390 - Timing Belt Skipped 1 Tooth or More.
Probable Causes,
-Timing belt improperly installed
-Camshaft position sensor improperly installed
-Camshaft position sensor connector improperly connected
-Crankshaft position sensor connector improperly connected
-Camshaft's relative position not relearned after one of the following have been serviced: Camshaft, Camshaft sprocket, timing belt tension-er, cylinder head, head gasket, crankshaft sprocket, crankshaft cylinder block or the PCM.

Sounds like something to do with the timing belt it self. You can go to any Autozone or Checker and ask for a code reader (they will let you use it for free) and it will show this code again. You can also reset the cars computer with the code reader to see if it comes back with the same code.

How do you check and change a camshaft position


The camshaft sensor wouldn't explain the clattering noise. But a timing chain would explain both. Clattering from a loose chain and the camshaft sensor code from when the chain broke and the camshafts stopped turning.

After changing the camshaft censor and the car still wont start what could be the problem also is there a fuse that needs to be replaced this is a 2004 pt cruiser the code say its the camshaft censor also...


P0016 crankshaft/camshaft timing misalignment
p0340 camshaft sensor

intermittent crankshaft sensor

PCM detects an error when the camshaft position is out of phase with the crankshaft position
