The cam sensor is the distributor, The crank sensor is in the front bottom left side of the timing cover. Behind the balancer.
try replacing crank sensor
yes but the cam sensor and the crank sensor work to geather so make sure to have it tested if you can to make sure wich is bad .
In the back by the coil pack.
I don't think it has one only crank sensor. It is right under the balancer it takes a number ten socket and then pulls out
The crank sensor is on the left side top of the bell housing behind a shield. One bolt to remove but be careful as the wires are extremely thin.
1391 is for an intermittent loss of the cam sensor or crank sensor signal

crank position sensor
It's a pain in the neck, the sensor is under the engine mount by the starter and the mount has to be removed to access the sensor.
