Camshaft Position Sensor on a 302 5.0
So, recently had a CEL come up on my Explorer. P0340, if you’re interested to know. The code is “Camshaft Position Sensor Circuit Malfunction”. The likely causes could be the CPS, PCM, or a short/break in the wire. I’m going to give the wires a look over first, but if I don’t see anything I’m going to swap the CPS. I already have a spare, so it’s cost effective. Any tips and tricks on how to do it? I’m sure the location and method of removal/installation is the same on all newer OHV 5.0s, including the Mustangs and F series trucks. Any help would be appreciated!

You might want to have the battery tested first, and the alternator..That code on the mustangs, is generally associated to a bad alternator, or bad connections to the battery.. Might save you some time in doing the sensor if it is a bad battery connection, or bad alternator..
(EDIT) yes. it is a bad “Camshaft position sensor, or a bad ground, or whatever in the CPS, but the cause is generally electrical related.. and above is generally the cause..
Just wound up putting a new battery in it, as the last one died from sitting too long. The code came before the battery swap, and is still there afterwards. I know that the alternator is good, as before I swapped the battery, I had to use boost cables to start it. It contained no battery, and kept on running. This was with the stereo in it turned up a fair bit.
