The service light is on. I had a check run and was told the camshaft sensor was the problem. But they can't find it. Can you tell me where it is located this is on a 1998 Saturn SL1 with auto transmission.

It doesn't have an actual camshaft sensor. What they do is monitor the collapsing electromagnetic field of the 1-4 coil with the ignition module.
The fix is to remove the two coils, remove the ignition module, and using a scotchbrite pad clean the module mounting surface on the transmission thoroughly. Once it is cleaned reinstall the module and the coils. Use new bolts that are available from Saturn/GM dealer. Clear the codes. and you should be good to go.
In rare cases the ignition wires and/or the ignition module will also need to be replaced.
This is or was a pretty common problem with saturns. There is a TSB for it.

You need a mechanic with a professional grade scan tool computer. That will do a full scan of the vehicle and say which part is causing the transmission not to shift. Is the Engine Malfunction Light on? A simple scan tool can read those.
What Are the Symptoms of a Bad or Failing Camshaft Position Sensor?
Check Engine Light Comes On. The most common indicator that the camshaft position sensor is failing is a lit Check Engine light. ...
The engine light is telling you that the CPU has found sensor/s outside set parameters during the checking process. Have the fault codes read before wasting time and money guessing what has failed. Replace with genuine items only as aftermarket units are not always compatible with the settings in the CPU.
CMP Sensor connector is damaged, open or it is shorted.CMP Sensor signal circuit is open or shorted to ground or to battery voltage or 5v supply circuit.CMP Sensor 5v supply circuit is open or shorted to ground or to battery voltage.CMP Sensor ground circuit is open.CMP Sensor is damaged or has failed.CKP Sensor is damaged or has failed.PCM has failed.I would make a copy of this and tell him that the camshaft needs to be replace or what ever is causing problem,they probaly know.
P0340 - Camshaft Position Sensor 'A' Circuit Malfunctionhttp://engine-codes.com/p0340.htmlForum CodePossible causes- Camshaft Position Sensor harness is open or shorted - Camshaft Position Sensor circuit poor electrical connection - Faulty Camshaft Position Sensor - Faulty starter motor - Starting system circuit - Dead (Weak) battery Tech notes Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code. When is the code detected?The camshaft position sensor signal is not detected by the Engine Control Module(ECM) during the first few seconds of engine crankingSymptoms- Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of Power - Engine StallP0340 Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.
Hi there: The camshaft sensor is located in the hood, beside the engine. However, it isn't always easy to find it. This is because the exact position of the camshaft sensor depends on the car brand. That said; whichever the car, you'll find the camshaft sensor in either one of three locations: by the side of the engine block, behind the cylinder head, or in the car's lifter valley.
The camshaft sensor is a small, but significant, magnetic device. It gathers and sends information about the car's camshaft speed (and as a result the position of each piston) to the car's electronic control module. This information is received by the computer, which then uses this data to further calculate the time of ignition and the timing of fuel injection required by the engine. This information is vital for engine function.
At times, either due to accidents or due to wear and tear, the camshaft sensor can weaken. In the case of a camshaft sensor failure, the weak or disrupted signal is interpreted by the computer as a problem, and this affects the proper running of the vehicle. A failing camshaft sensor can be identified based on any one of the 3 following symptoms.
1. "Check Engine" Light The first symptom of a failing camshaft sensor manifests as a warning from the car's control module. As the camshaft sensor fails, the computer sends the driver a warning sign via the "check engine" light on the cars dashboard. When the check engine light first comes on, the driver has enough time to service the car and replace all faulty parts, including the failing camshaft sensor. However, if you ignore this flashing light for a considerable time, it could later lead to severe engine trouble.
2. Disrupted Driving Another symptom of a failing camshaft sensor is experiencing constant disruption while driving. If you are experiencing symptoms like frequent stalling, poor idling of the car at 500 to 600 rpms, a massive drop in the rpms slowing down the car to a crawl, a noticeable drop in engine power, poor mileage, abnormal acceleration activity, frequent stumbling, etc., it probably means you have a failing camshaft sensor that needs immediate attention. If you are experiencing these symptoms, it is best to seek a mechanic before the situation gets worse and the car gives up, refusing to start at all.
3. Ignition Trouble If you ignore all of the above symptoms, you end up with one that really can't be ignored-no ignition. Remember, as the sensor begins to weaken, so does the signal it transmits to the cars computerized control station. If you let the problem carry on for too long, the engine will suffer from a "no spark" situation. Once the signal switches off, so will your engine, thereby stranding you. Thus, it is best not to let your car get to this stage.

Yeah so bank 2 is the drivers side and 5678 are on that side you posted this in ford so it's either a 5.8 Windsor motor or a 5.4 and the camshaft sensor is on the timing cover under the valve cover about 2 inches or so go to rockauto.Com and look up your vehicle and the parts described here then you can see it before you buy it
I have a 1999 BMW 740 il My SES light came on so I hooked up my OBD code reader p0340 - Camshaft Position Sensor Circuit Malfunction is what came up. so I went to the BMW parts department and bought the Camshaft Position Sensor.
I Replaced the with the new. My SES light was still on so I hooked up the OBD reader again hoping it may reset my SES light but it didn't what did happen is the OBD reader came up with the same code (p0340 - Camshaft Position Sensor Circuit Malfunction) witch is what I just replaced. now I'm at a loss. I'm not sure how to reset my SES light and if I just replaced the Camshaft Position Sensor why dose it the OBD code p0340 still come up. Any suggestions?
hi, i have infinity fx 35 2003 it light on the service engine camshaft position sensor bank 1 , i replaced the bank 1 after 3 hour it light on again service engine + VDC off and slip i put the scanner it told me camshaft position sensor bank 1 again what can i do ?
