Try replacing the crank shaft position sensor. Normally 7x and 24x were only used for the 3.1 engine. The 7x crank sensor is in the side of the block and the 24x crank sensor is behind the balancer, but that is only on the 3.1 engines. I don't know why you would get that code for a 2.3? Anyway the crank sensor is at the back of the engine on the 2.3.
Good luck.
