Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
The common cause for the code P0341 to set on your 3.4 is in most cases caused by a failing Camshaft Position sensor , that being said its best to test it before replacing it. Are you able to do the testing?
Well if you can get some help with testing it I have enclosed the steps. I suppose you could just replace the sensor and see it it resolves the code but testing is always the best step to assure your not throwing parts at it . See the steps in the link below for testing it as well as the sensor location. I will help you any way I can from here.https://dl.dropboxusercontent.com/u/104923897/Cam%20sensor%20location%20Sept%2024.pdfhttps://dl.dropboxusercontent.com/u/104923897/Cam%20sensor%20Sept%2024.pdf
Your very welcome and thank you as well. Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.Thank you again.
The pins at the sensor are marked. If you take a close look at them you should be able to see them.
That means if you are getting the square wave signal from the Sensor back to the PCM and the PCM is not reading then that would indicates its bad. Do you have the square wave pattern from the sensor at the PCM?
The cam sensor crates a square wave signal the is sent to the PCM, if the PCM can not read it then it would be a bad PCM. If the Cam sensor is not producing the signal then the sensor would be bad.
Unfortunately if you are not able to do the testing then you are going to need someone who can help you. I can not do that from here. You could just go ahead and replace the sensor and gamble on it being the proper fix but testing is usually the standard procedure to verify if in fact that is the case. I am not sure how to advise you from here. If you would like me to open the post back up for you I can do so. Let me know.
good afternoon my name is ***** ***** I will assist
in order to do the test Ron was telling you is to have a scope. I assume you dont have a scope.
do you have a volt meter???
ok, since you are not familiar with testing, you need to check for 5 volt reference signal to the sensor. if you have that signal, most cases is that the sensor has failed. the signal return that Ron spoke about cannot be tested unless you have a scope. like I said, if you have the 5 volt reference voltage, replace the sensor.
does that make sense???
please dont forget to rate me as it is the only way I get paid for my efforts
how did you make out
