If you removed the fuel injection system the cam sensor will not be needed. The cam sensor informs the computer about cyl identifacation for fuel delivery. If you now have a carb, it wont be needed so you can just leave it where it is

It sounds like it is running rich - possible injector poppets hanging open. Clean the injectors - You need to have a pressurized fuel injection done (which requires special tools). You will want to remove the mass air flow censor from the induction tube; remove the four torque bit screws; seperate two metal ends from plastic piece and clean the little wires on the censor with brake clean and used compressed air to dry.

Before changing anything else, I would suggest getting a can of starting fluid and spraying in the air filter. If the car starts then you will know that it is a fuel problem. If it doesn't start then it is going to be an ignition problem. If it is a fuel problem, you should take off the gas cap and listen for the fuel pump to come on for about 3 seconds.If you don't hear the pump then check to make sure that the pump is not getting power. If it is getting power then it could be the fuel pump driver module. If it is getting power then it is the fuel pump.

This diagram shows the sensor as being connected on the outside of the distributor. It may not have been replaced when the distributor was. This also has instructions for checking and changing it.

2000 trail blazier with random misfire,sulfur smell, glowing convertor. New cap,rotor button plugs,plug wires and convertor NO CHANGE ! ANY IDEAS ?

Is the check engine light lit ? Any DTC'S - diagnostic trouble codes ? What engine ? 4.3 L vortex . Leaking fuel pressure regulator under the upper intake manifold . Leaking fuel injectors ! Ignition timing problem . How does the engine run ? Who installed the plugs an wires ? are they right ? Fuel pressure leak down test, fuel injector balance testing . Check distributor drive gear an slop in the shaft . Did you have distributor out ? Is it in the proper position ? What cylinder is misfiring ? engine mechanical problem ! What do spark plugs look like ? fouled , soaked with fuel . Do a engine compression test .
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 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 CMP sensor will not affect driveability. The sole purpose of the CMP sensor is to provide the VCM with the necessary information for the misfire DTCs.

How do you change the Camshaft sensor on the 98 2.3 honda accord, i think it maybe inside the distributor iam not sure if it is or not.

The 1998 Accord 3.0L has a camshaft sensor. The 2.3L has a "Cylinder Position Sensor" (CYP), which is used to detect the position of the #1 cylinder for fuel injection purposes. This sensor is located internal to the distributor and if it fails, the distributor must be replaced as a unit.

p 0300 code is for random misfires
random misfires are more from dirty /faulty injectors or low fuel pressure than anything else
have a pressure test done to check pressure regulator , filter and pump operation
use a can of quality injector cleaner or remove and clean the injectors

Where is the cam position sensor on a 1997 chevy 5.7L

The camshaft position sensor (also known as the distributor pickup) is inside the distributor which is driven by the camshaft gear and directly below the water pump, the water pump must be removed to access the distributor to change the sensor. Here is a picture of the camshaft position sensor.

I received a P0340 on my 1995 Nissan Altima. It says I need to replace the Camshaft sensor. The dealers say that my car does not have one in it and that it may be in the distributor itself. Is this true....

They may be right. I cannot find the part. here is what the manual says:

REMOVAL & INSTALLATION The camshaft position sensor is located inside the distributor. On some distributors, the camshaft position sensor is not serviceable (replacement parts may not be available separately). If the camshaft position sensor is serviceable, use the following procedure.

  1. Remove the distributor cap and wires.
  2. Remove the rotor.
  3. Remove the camshaft position sensor cap.
  4. Remove the camshaft position sensor mounting screws.
  5. Carefully remove the camshaft position sensor.

To install:
  1. Position the camshaft position sensor in the distributor and tighten the mounting screws securely.
  2. Install the camshaft position sensor cap.
  3. Install the rotor.
  4. Install the distributor cap and wires.

If you did not put distributor back to where it should be then timming may be retarded or advanced. I would start there. Put distributor back to base timming. Put #1 cyl. at top dead center (TDC) remove dist. cap and take notice of were the rotor is pointing. Make sure that it is pointing at #1 on the cap. Further adjustments can be made later with a timming light. You may need to check the rimming specs and procceedure once you get to this point but base timming first. Good luck

Try the camshaft possition sensor. I know it sounds stupid being that you changed your distributor, but most are rebuilt and they only check the continuity not function of camshaft sensor. Hope this helps!
