Cam Sensor Battery Voltage

Cam Sensor Battery Voltage. Easy to use with microcontrollers. If reading is about battery voltage, go to step 11).

Disengage the wiring harness connector from the cmp sensor. Remove the ignition coil, radio capacitor and ignition coil bracket. I charged the battery and still won't fire.

The Battery Voltage Was Showing Yellow, 12.2V.


The cam sensor on your 4.6l or 5.4l ford pick up (or suv) is a variable reluctance type sensor that has two wires coming out of its connector. Not only that, to produce this digital dc signal, the three wire type crank or cam sensor needs an external voltage power source (unlike the two wire type crank or cam sensor). The power to the red wire at the cam sensor comes from the computer so you will need to see if there is power on terminal 39 at the computer, if there is there must be a broken wire between the computer and the cam sensor.

Circuit goes hot when you turn on the key. So unpluged u will alwase have 2 5v wires and one 60 ohm ground wire. Measure voltage at cmp sensor harness connector between sensor feed circuit and sensor ground circuit.

The Way The 5Volts Work Is The Pcm Gives 2 5 Volt Signals And When The Switch Closes U Get A Voltage Drop Across The Switch And The Pcm Knows By The Drop Where It Is Based Off The Voltage.


The sensor may also monitor the voltage, state of charge and state of health of the battery (aging). Using the signals of the crankshaft position sensor and that of the camshaft position sensor the ecu can tell which piston is in the power stroke and which one is in the intake stroke. Use a voltage tester at the fuse, with key on, anything?

The Battery Monitoring Sensor Monitors An Individual Cell Or Bank Of Batteries, As Well As Dc Power Systems Like Solar Panel Arrays.


In some cars, it even measures the temperature of the battery. It rises back to 12 volts when the pin leaves the sensor head. If reading is not as specified, go to next step.

So I Took Out The Old Grey Version—The Original Black Cps Had Long Since Been Replaced—And Threw It.


Measure voltage between cmp positive connector at cmp sensor harness connector and ground. If the voltage reading varies more than 0.1 volt ac, the sensor is okay. The cmp sensor determines whether a cylinder is on a firing stroke or on an exhaust stroke.
