Why is the camshaft out of sync on my Chrysler 300M?
Why is the camshaft out of sync on my Chrysler 300M?
They are out of sync and suggest that I should bring back to the dealer who replaced the timing belt. When I brought the car to the dealer, they told me that chrysler 300m 2004 tolerates up to 12 degrees difference so the cam and crankshaft are not out of sync. Nothing to do with the timing belt that they installed.
Why are the timing marks on my camshaft out of sync?
The cam and crank sensors must be synced exactly. It doesn’t matter if the belt is made of rubber. It’s a reinforced rubber belt so it can’t stretch to compensate for the mistiming. This shows how the timing marks must align exactly when installing the timing belt on your engine. http://www.ricekiller.com/forums/thread76681.html
Why is my p0016 Cam sync signal not working?
P0016 cam sync signal can be caused by an intermittant cam signal or the belt is installed wrong. Checking the fuel trim data can support the suspicion of the belt being out of time, the bank that is off will show +10% or more greater fuel trim than the other side. This may be why they believe the oxygen sensor needs to be replaced.
How many degrees can a camshaft be out of sync?
And the car can tolerate up to 12degrees differences in camshaft and crankshaft sensor. I’ve seen old timing chain engines with the chain worn badly enough that the cam timing is retarded 5-10 degrees.

Do you need a crank signal to start a Chrysler engine?
For a Chrysler engine to start, the PCM must receive a good signal from both the CKP and CMP sensors. Once the engine is running, the cam signal is no longer needed for operation on vehicles built after 1996. However, the PCM needs the crank signal to diagnose a potential problem with the cam signal, and vice versa.
Why are the cam and crank sensors out of sync?
The independent mechanic is correct. The cam and crank sensors must be synced exactly. It doesn’t matter if the belt is made of rubber. It’s a reinforced rubber belt so it can’t stretch to compensate for the mistiming.
When does the cam signal no longer need to be in sync?
A scan tool can report on the presence of the CMP and CKP signals, and whether they’re in sync. For a Chrysler engine to start, the PCM must receive a good signal from both the CKP and CMP sensors. Once the engine is running, the cam signal is no longer needed for operation on vehicles built after 1996.
What to do if your crankshaft is out of sync?
The ignition timing can be compensated for by simply rotating the distributor as the chain and gears wear…Even with the cam timing retarded, these engines seldom have any drivability problems…
