Where is camshaft sensor on nissan altima

The camshaft position sensor assembly is really a crank sensor, since the fuel injection computer uses it to control the creation of spark thru' the power transistor and ignition coil. As the engine turns, the camshaft position sensor assembly starts to create two specific position signals that it sends directly to the computer.

When the computer gets these two camshaft position signals, it does its little song and dance and shoots a Triggering Signal to the power transistor. When the power transistor gets the Triggering signal from the fuel injection computer, it now starts to switch the ignition coil's power On and Off.

If any one of the two camshaft position sensor signals is missing, your Nissan Altima will crank but not start due to a lack of spark. The first order of business is to check and verify that the camshaft position sensor is getting juice, in the form of 12 Volts.

The wire that delivers these 12 Volts to the distributor is the wire labeled with the number 5 in the photo above. With the red multimeter test lead, probe the wire labeled with the number 5 , see photo above. Connect the black multimeter test lead directly on the battery negative - terminal. This is the correct test result and confirms that the camshaft position sensor is getting power.

The next step is to check that the camshaft position sensor is creating its two position signals. This tells you that the cause of your Nissan Altima's no start is due to this missing voltage, since without this voltage, the distributor is not gonna' work.

Although it's beyond the scope of this article to troubleshoot this missing voltage, finding the cause of these missing 12 Volts will solve you no-spark no-start condition on your 2.

Home Misc Index Chrysler 2. After we cut off the camshaft position sensor wire harness connector, all we had to do was splice it up to the '02 Altima with butt wire connectors. If necessary, you could also just twist the wires together, wrap them in electrical tape and use cable ties to secure the tape. Thank you! Note: I am not a registered charity.
