I cant find a detailed picture of where the location is to check these items.

Hello Rod, your Camshaft position sensor will be located on the engine, usually around the accessory drive pulleys. Your local Auto parts retailer will be able to provide a accurate drawing detailing the location and wiring colors.

it depends on the vehicle. and you did not say what type of vehicle. most general motors C/S sensors are located at the front of the engine above the timing chain cover . some are located on the Rt. sice of the cylinder head

For testing crank sensor,check the help link below:---How to test Crankshaft Position Sensor? http://fordrepairhelp.blogspot.in/2012/03/how-to-test-ford-focus-crankshaft.html

Fig. 1 Camshaft Position Sensor - 2.4L DOHC
The camshaft position sensor is mounted to the rear of the cylinder head.

Sounds like the Crankshaft sensor is damaged and needs to be replaced.
The Camshaft position sensor works along with the Crankshaft position sensor.
Determining the timing and injectors’ pulse, to deliver fuel to the cylinders.
The Camshaft position sensor is a hall sensor, which it triggered by a magnet in the Camshaft.

On 4 cyl(2.4) models the Camshaft position sensor is located to the left side of the timing cover.
On the V6(3.1 & 3.4) it’s located at the front of the engine block (passenger side), below the power steering pump.
Check the terminals for breaks and looseness, repair if needed.
Here is the plug indentification picture.
The wires are different for the 4cyl and V6, Please note below.
Though the plugs are the same three wire connectors.
Plug is as listed : 1 - Camshaft position sensor signal on 4 cyl,
12 volt supply on the V6
2 – Sensor ground 4 cylinder,
Camshaft position sensor signal on the V6
3 – 12 volt supply on the 4 cylinder,
sensor ground on the V6

First check for voltage and ground circuits from the PCM.
Disconnect the electrical connector from the Camshaft sensor and connect the positive lead (on the wiring harness) of the voltmeter to the red wire(#3) on the 4 cyl and the red/white wire on the V6(#1).

Connect the negative to the pink/black wire on the 4 cyl(#2), or black on the V6(#3).
Turn the key on, the voltmeter should read 12 volts, if not check the wiring to the PCM.
If the circuits are good, have the PCM checked out by a Dealer or other properly trained shop.
To check the operations;
Reconnect the Camshaft position sensor, using a probe to back probe the brown/white wire terminal of the camshaft PS. Plug locations on4 cyl (#1) and theV6(#2)
Connect the positive lead of the voltmeter to the probe and the negative to a good engine ground.
Turn the key on, the voltmeter should read approx 10 volts.

*Rotating the engine by hand with a breaker bar attached to the crank pulley. Watching the voltmeter, the voltage should remain a steady 10volts then quickly drop to zero and back to 10vlts as the magnet passes the sensor.
If the tests results are incorrect then replace the camshaft position sensor.

* Rotating the engine slowly, and at least two full revolutions of the engine for accurate results.


Camshaft sensor Replacement

On the 4 cylinder
- Disconnect the electrical connector
- Remove the camshaft position sensor-mounting bolt and pull the sensor out of the camshaft cover.
- Replace the “O” ring and lightly lubricate it with clean engine oil.
- Install in the reverse of those procedures.

On V6
- Remover the drive belt.
- Remove the power steering unit but don’t disconnect the hoses, just lay it aside.
- Disconnect the electrical connector from the harness; paying attention to the route the wires are in.
- Remove the camshaft ps mounting bolt and pull the sensor out of the block.
- Install in reverse procedure.

If the sensor flange breaks off and you cant remove the CPS, try screwing a heavy screw into the top of the sensor and pulling it out with plyers/vise-grips.
Good luck and thank you for using Fixya

P0340 OBD-II Trouble Code
Technical Description
Camshaft Position Sensor Circuit Malfunction

What does that mean? This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms
Symptoms can include:

• Hard starting or no start
• Rough running / misfiring
• Loss of engine power

Causes A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

Possible Solutions With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Visually inspect all the wiring and connectors in the circuit
• Check for continuity in the circuit wiring
• Check the operation (voltage) of the camshaft position sensor
• Replace the camshaft position sensor as required
• Check the crankshaft position circuit as well
• Replace circuit wiring and/or connectors as required
• Diagnose/replace the PCM as required

Also, the cams/crank are out of alignment, thats why you are getting a cam position code (P0340). For more details about your model, you can visit autozone.com (free register)

Hope helped whit this (remember rated this help) Good luck.

The camshaft position sensor sends a signal to the PCM, powertrain control module. The PCM then determines spark plug firing. Could be the camshaft position sensor.

1996 is all I have
Camshaft Position (CMP) Sensor 3.0L (2V) Engine
The camshaft position sensor (CMP sensor) (12126):

• is a single Hall-effect magnetic switch activated by a single vane which is driven by the camshaft (6250).
• provides camshaft position information which is used by the ignition coil (12029) and the powertrain control module (PCM) (12A650) for fuel synchronization.

3.0L (4V) Engine
The camshaft position sensor (CMP sensor) (6B288) is:

• a variable reluctance sensor.
• triggered by the high-point mark on the LH exhaust camshaft sprocket (6256).
