What he said, these usually get full of water. However, once they start to give problems, it is usually best to replace them .

 

My cossies crank position sensor was full of water. This was causing faults on my car when i first bought my car. I cleaned the connection out and put electric tape round the connection to stop anymore water getting in.

 

this is a regular thing on the cozzy and can be caused by bad earths on the inlet manifold and elsewhere on the engine,also the 3 big block connectors at the back of the engine bay are also known to be a cause of this problem,have a check of all the engine earths and open and close the block connector a few times to make a good connection and do the same with the ignition amplifier connector

 

I will have two have a look at my car. Its mad cause the fault with mine is only every now and then.
