    I have the same problem. The car seemed like it was missing on a cylinder so I checked the plugs and wires and was getting good spark on each one. I took it to a shop to have them check the computer code and it said camshaft sensor. The mechanic told me this car does not have a camshaft sensor and that I needed a new ignition module. Would a faulty ignition module cause a camshaft sensor code to appear and is a camshaft sensor the same as a crankshaft sensor?

    Yes, the resistance on cylinder 4 compression fire is what causes the code. It most like is not the module, but rather a bad wire, plug or ground on the module itself. Try changing plus, wires and clean all grounds and contacts on module and coil with steel wool.

I hate to tell you this, but there is not Camshaft Position Sensor on any 1.9L Single or Dual OHC. I assume you had someone read a Diagnostic Trouble Code from your PCM. They probably told you that you needed a Camshaft Position Sensor, and then offered to sell you one. I would recommend changing your spark plugs and your plug cables with FACTORY REPLACEMENTS. This will usually make the DTC go away. Aftermarket plugs and wires rarely work well for this engine. If you are looking for a CRANKSHAFT position sensor, look between the engine and transmission on the back side of the transmission. It is also known as the "transmission input speed sensor". More often than not though, your engine will not fire up if the Crank position sensor is not working. Hope this helps.

    I have the same scenario right now (2002 Saturn SL1 with cam pos sensor code and Check Engine light). My mechanic says there is no Cam Pos. Sensor, and suggested I go to a Saturn dealer. I'm going to try the Saturn plugs/wires first however. I'll report back. Danny from Eagan, MN 2/2/11

    A Saturn tech informed me that this code can be caused by the corrosion on the bolts that hold the ignition module and coils to the bracket. He said that the module is grounded through these bolts and that removing and cleaning them often fixes the problem.

    I'm confused...the dealer says there is no camshaft in a 2002 SL2 Saturn. Yet they sell camshafts for this vehicle online.Which is it??

Yes there is a such thing as a camshaft position sensor, for gods sake they sell the replacement part! It's location is hard to get to as it's located behind the starter, I've replaced two of them so far failing after only about 30k miles use. From what I read Saturn's often have these fail and symptoms are car running until warmed up and then shutting off and not restarting until it cools down again.

    how much will this cost to have part and labor done?

    These cars do not have a camshaft position sensor. The computer reads the current to fire the spark plugs during the wastes spark cycle and uses that to determine camshaft position. Worn spark plug wires or corroded grounding lug can cause this code to come up

I can't find the camshaft position sensor. I don't know much about this stuff. I have went to auto zone and advance auto and heard 3 different stories. Came home and tore the car down 3 different places...


The cam shaft position sensor is located right behind the exhaust cam by the fire wall. It is held by two 10 mm bolts, one on each side of the sensor. If you got the hood up and looking at the engine the cam that is on the right hand is the exhaust cam. To get to the CPS you have to remove the intake and cam top cover.

Thank you for using fixya and good luck. Auto Zone or Part Source will have the part you need and the instructions no how to do it.

Engine light is on...


P0137--O2 Sensor Circuit Low Voltage-Bank 1 Sensor 2

P0139--O2 Sensor Circuit Slow Response-Bank 1 Sensor 2

P0152--O2 Sensor Circuit High Voltage-Bank 2 Sensor 1

P0300--Random Multiple Cylinder Misfire


I would suspect that the camshaft position sensor is bad. This is a quote from the tech manual:

The Powertrain Control Module (PCM) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The PCM constantly monitors the number of pulses on the signal circuit. The PCM compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the PCM receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the PCM. Some PCM systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the PCM misfire diagnostic will likely be affected.

The part costs $50.....simple to change. It is NOT the O2 sensors so don't go wasting money on those. They are being affected due to related symptoms....they fault because the problem is happening upstream.

I did a diagnostic test at home on my 04 Dodge Stratus and it said something about a camshaft malfunction/failure. Can u tell me how much getting that fix cost? Or how much a camshaft cost?


That would be a cam shaft sensor issue .The cost of the sensor is about $65 With about .8 hours of labor .So for about $150 you can have the sensor installed :)
