P0340 Camshaft Position Sensor Circuit Malfunction

Breeze, 4 cylinder: check fuse # 5 (20a), fuse #1 (10a), fuse # 10 (10a)- in the power distribution box. Check for power to the coil on the dark green wire with orange stripe. If power there, test the coil. If coil is good, suspect the cam position sensor or the crank position sensor.
Breeze, 6 cylinder: check fuse # 5 (20a), fuse # 10 (10a). Check for power to coil on the dark green wire with orange stripe. If no power to coil, try a new or known good Auto Shutdown Relay (in the power distribution center). If still no power to coil, may be a problem in wiring harness. If there is power to coil, and still no spark, test the coil. If coil is good, suspect the cam position sensor (in the distributor), or the crank position sensor. If all check good, may be a problem in the wiring or the pcm (computer).
Good luck.

good posability

I guess my problem was the new crank sensor has failed.
Replace crank sensor again , it has fixed the problem.
Not too sure if this was any help or not.

If i remember, it's located near the passenger side of the car behind the oil filter. There should be 4 screws holding it in place in a square pattern, 1 in each corner and the size is around 5mm.

Hope this helps.

Most probably ur crank position sensor or the pick-up coil is defective (or nearly). What that does is the computer knows where the No.1 cylinder is so that he knows when to send the spark to the correct spark plug. Now ur computer doesn't seem to know where the No.1 cylinder is, so he fires at random. Eventually the spark lands at the right place at the right time, hence ur engine is long to start.
That is my best guess.
