SOURCE: 2005 Dodge Stratus ? Camshaft Position Sensor causing problems (I

I had the same problem with my '05 Stratus SXT 2.4 DOHC. I've replaced the cam pos sensor and it seems to be running fine right now. On the Dodge forums a lot of the guys say that you need to replace the crank pos sensor too. I've bought one of those just in case it comes back again. Hope this helps.

SOURCE: Where is the cam shaft position sensor located?

It's not that hard to replaced, and can be done with common tools.  3.4 camshaft sensor removal:
Remove the serpentine belt, Disconnect the sensor wire harness, Remove the power steering pump (just remove it from the mount and out of the way), Remove the attachment bolt to the sensor, Remove the sensor, (note spray around the sensor with brake parts cleaner before removal to keep dirt from entering the engine)
To install: Lubricate the new O ring with engine oil before installing the new camshaft sensor, Tighten the retaining bolt to 8 ft.lbs.  connect the sensor's electrical wire, reinstall the power steering pump, reinstall the serpentine belt. 
Start the car and go out for the night with the money you just saved, You can pick up the camshaft sensor at Auto Zone and they can also give you the step by step instructions to getting the job done. Good luck and hope this helps. Take's just under 1 1/2 hour to do. You can do it in under 1 hour though if your good with tools.

The crankshaft should have the timing mark on the crank pulley (Notch in the outer edge of the pulley near the keyway) It should align with the timing mark on the oil pump. (With the keway turned to about the 3 O'clock position.)

Align the marks on the camshaft timing pulleys with the corresponding dots on the front plate.

If you are installing a new belt, it should have 2 solid white lines printed on it that you would align with the timing marks on the cams and a dotted white line to align with the timing mark on the crank.

It makes a difference which way you put the belt on. (Which edge faces the front of the engine.) Most, but not all brands of belts have arrows and the word "FRONT" on them to tell you which edge of the belt shoud face the front of the motor. If there is no mark to tell you which edge is front, the letters on the belt must be able to be read correctly as viewed from the front of the vehicle.

Hi trying to set the timing on my j1 elantra its a 16 valve and each cam has two marks on it.so my question is what positions should the cam lobes be at when timing is supposed to be correct.thanks


no 1 piston tdc
the cam lobes for no 1 piston should in such a position so that a slight turn of the cam shaft one way makes the exhaust start to close and the inlet start to open or the other way the inlet start to close and the exhaust start to open
this is known as valve rock or valve overlap and occurs when the cam shaft is properly timed to the tdc position of the piston
for a twin cam engine the cam lobes position will be the same operation just that the inlet cam rock will be for the inlet cam and the exhaust cam rock will be for the exhaust cam

It seems to me that if the belt breaks , even on an interference engine: the valves will slam shut . Maybe it 50/50 chance either way.


belt has to be replaced any way
compression test on the cylinders.. tells you straight away
zero or low compression numbers ..valves bent

in an interference engine OHC or DOHC belt breaks
the cams stop dead and pistons continue to move up and down

non interference there is a gap between pistons and valves

These are interference engines. If the timing belt was never replaced and the car has over 120000 miles on it, I bet the belt broke and then the pistons hit the valves and you have trouble.

Without spark plugs in, you should be able to use a large wrench to turn the engine. If there's any resistance, you probably have a piston touching a valve.

What I would do is to remove the valve cover and possibly the cams, then with all the valves closed, see if I can turn the crank over.
You might be able to get a small inspection camera down the spark plug holes to look in the cylinders, and maybe even with all the valves closed do a leak-down test to see if the valves are sealing.

If you can get all the valves to seal, they're not bent or broken AND the pistons are sealing well (meaning, no holes in them). Then you could adjust the timing and put a new belt on it and see if it runs.

Actually - that might be the best way to start. Align the cams and put a belt on, then rotate the engine to where you can leak-down test each cylinder. Any big leaks and you have a problem.

A used engine might be a good idea, but I'd verify there's a problem first. You CAN get lucky and the belt broke when the engine was started and nothing got damaged.

Cam timing for ford focus 2004 duratec 1.6


Are you needing the twin independent variable cam timing info or is this a cam replacement initial cam timing setting? the variable valve timing itself is dependent upon the part design, and is usually controlled by oil flow (causing the timing to change hydraulically and seems transparent to the driver). However, when replacing the cam, the timing is more of a position issue using the marks on the engine and camshafts to make sure the shafts are in the proper position.
If this is for a replacement, use the marks on the block ensuring the current valve position is the proper in relation to piston position (otherwise your pistons will punch the valves and blow the head)

2002 VOLVO S80 T6 CODE P0017


the word correlation means relationship between two or more items . In this case it means that when the crank shaft sensor is triggered then the camshaft sensor has to be in agreement that the position of the piston and valves is in the right position to allow spark and fuel.. there are air gaps between each sensor and the rotor that triggers them and if this is not correct or there is dirt in the air gap ( the sensors may be a bit advanced or retarded in the fitment holes) then this relationship of positions is being interfered with and so you get the fault code. If after rechecking the fitment of the sensors and using a scanner to put the engine light off ,you still have a problem ,I would suggest that you find an accredited shop the does a lot of work on your make of car to assist with the fault.

Finding out how to find lost cam timing mark on a 1997 volvo 960


you are in a bit of a bind. Turning the engine over will result in bent valves so do not touch the crank shaft. you have to loose off all the rockers/ cam followers even to the point of removing the cam shaft. having done that remove no1 cylinder spark plug and by the use of a thin piece of wire turn the crank until the piston reaches top dead center. find this by rocking the crank back and forward until the piston dose'n move up or down check for the crank timing mark next replace the cam shaft and position the cam lobes for no1 piston in such a position that the inlet and exhaust valves move slightly up or down when the cam is moved slightly left or right. this is called valve over lap and with the piston on top dead center means that you now have valve timing for the engine. Cam timing marks can be dot on gear to shiny link on chain or if using a belt a dot on tooth lineing up with mould mark or join on head before starting up do a compression check to prove that there are no bent valves. if you are not mechanically minded enough to attempt the valve timing method it may be cheaper in the long term to let a qualified person do the job

On driverside of engine, oil leaking out around where I call the back cam ( one closet to firewall) at end. I am talking about opposite end from timing belt on engine. If I removed cap ( w/two star screws...


That seal typically comes with a pack that includes all the cam bearing seals and the valve covers seals. It very easy to replace. Remove the valve cover and discard the old seal, remove the old cam shaft bearing cap seals. Replace the bearing cap seals and the valve cover seal and replace the cap and cover. Tighten the bolts to about 30 lbs and that should resolve the problem.

What about it??
I wouldn't try it if you don't know how, (specially if this is what is known as an interference engine). Valve timing is *very* delicate and stray pistons love to chew them up!
