What does the cam sensor inside the distributor do?
NOTE: The following ignition system wiring diagram may be of help: Ignition System Wiring Diagram (1998-2000 2.5L V6 Chrysler Sebring). The camshaft position sensor inside the distributor, in conjunction with the RPM info the crankshaft position sensor provides, is used by the PCM to control injector pulse width and ignition timing.
How to test the camshaft position sensor ( 1992 )?
The distributor cap must be in place to hold down the camshaft position sensor. With the red multimeter test lead, probe the tan with yellow stripe (TAN/YEL) wire of the cam sensor connector. NOTE: The camshaft position sensor must remain connected to its engine wiring harness connector to be able to read its signal.
How to know when to replace your camshaft position?
The same procedure applies for the crankshaft sensor. Diagnose the problem through the process of elimination. Taking into consideration that the cam sensor has a direct effect on the operation of the fuel injectors and the crank sensor on the ignition, check for spark at the plugs. Pull one of the spark plug wires off one of the plugs.
Is there a Hall effect sensor on the camshaft?
The camshaft sensor and the crankshaft sensor, although both hall effect sensors, serve different purposes. They both can be diagnosed using similar procedures. Neither sensor should have any glitches or dropouts in their respective sine waves when checked on an automotive oscilloscope.
NOTE: The following ignition system wiring diagram may be of help: Ignition System Wiring Diagram (1998-2000 2.5L V6 Chrysler Sebring). The camshaft position sensor inside the distributor, in conjunction with the RPM info the crankshaft position sensor provides, is used by the PCM to control injector pulse width and ignition timing.
Where is the camshaft position sensor located on a car?
The camshaft position sensor is generally mounted in the block or cylinder head, depending on engine design. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector. Remove the electrical connector by pushing down on the tab and sliding it off.
How does the Hall effect work on a camshaft sensor?
The Hall effect design has three wires going to it: reference, signal and ground. The PCM sends a reference DC voltage to the camshaft sensor and the sensor sends a return signal back to the PCM in accordance with camshaft position.
How much does it cost to replace a camshaft sensor?
The camshaft and crankshaft position sensors are vital for proper engine operation. A failing sensor will often not allow an engine to start, or it will run terribly. Replacement of these sensors costs a few hundred dollars at the dealership, but armed with some DIY knowledge you can save a lot of money.
What kind of distributor gear do I need for roller cams?
If you have an austempered ductile iron hydraulic or solid roller cam, your two options are: 1. Melonized or hardened steel distributor gear 2. Composite distributor gear 1. Bronze distributor gear 2. Composite distributor gear cores. If the steel gear is not hardened, it is not compatible with either of the roller cam types. it will work fine.
How to test crankshaft and camshaft position sensors?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.
How do you test a Hei performance distributor?
To test for a good ground, a jumper wire can be attached to the distributor by connecting it anywhere on the housing and running it to the negative side of the battery. If all of that checks out, the following steps will help you to test the coil inside the cap, and the magnetic pick up.

What does distributor reference Hi signal mean on ignition module?
This digital signal is called the: Distributor Reference Hi Signal in the majority of the service literature. Also, after receiving the pick up coil signal, the ignition control module starts to switch the primary current (of the ignition coil) On and Off.
How often should a performance distributor test a module?
Sometimes, heat can cause these to not work properly, so it is recommended to have them test the module 3 – 5 times as the module may not show to be bad until it develops some heat.
