Crankshaft reluctor ring.
Camshaft position sensor.
Ignition control module.
4 separate ignition coils.
Eight spark plug wires and conduit.
Eight spark plugs.
Powertrain Control Module (PCM). Camshaft Position (CMP) Sensor
Right hand rear of the engine, near the power steering pump

Ignition coil driver module
Crankshaft position (CKP) sensor
Now which part do you want to replace ?
Cap and rotor
Camshaft position sensor
Gear drive and shaft
The camshaft drives the distributor shaft which rotates providing a spark to the correct cylinder by way of the cap and rotor. The camshaft position (CMP) sensor functions much like the crankshaft sensor previously described but provides only a 1x signal to the VCM. That is, for every 2 rotations of the crankshaft, there is 1 rotation of the camshaft. Note that the camshaft position sensor will not affect driveability. The sole purpose of the camshaft position sensor is to provide the VCM with the necessary information for the misfire diagnostic trouble codes (DTCs).

This diagnostic trouble code (DTC) is generic and applies to all makes & models of vehicles. The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.
The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together.
If the PCM detects that the crank and cam signals are out of time by a specific number of degrees, this DTC will set. Bank 2 is the side of the engine that doesn't contains cylinder #1, the "A" sensor is most likely the intake camshaft side.
Note it is not uncommon on certain models to see this DTC in conjuction with P0008, P0009, P0016, P0017, and P0019. If you have a GM vehicle and have those multiple DTCs, check for service bulletins that may apply to your engine.
Symptoms of a P0018 will or may include:
