Causes and Fixes Ford P0345 Code: Camshaft Position Sensor “A” Circuit (Bank 2)

How to fix a Ford P0345 engine code: Camshaft Position Sensor “A” Circuit (Bank 2)

The P0345 Code is triggered when the ECM detects an inconsistent signal from the Camshaft Position Sensor.
The Camshaft Position Sensor measures the rotational position and speed of the camshaft. The ECM uses this information to control the ignition spark and the fuel injector timing.

Possible Causes of a Ford P0345 Code:
Bad Camshaft Position Sensor
Wiring Issue
Bad Phaser
Timing Components (Belt, Chain Tensioner)

By using this information user assumes all risk of use.

Excellent video, puts in detail the possible causes for that code and, thank you

My son's car, a 2014 Infiniti Q70 3.7 L, V6, died and would not start. Brought it to my mechanic and he said the engine is gone. We changed the Fuel Pump and the Camsfaft sensors (both). Now the reading my mechanic is getting is P3045. He said that they will have to open the engine to check out what you mentioned and that would cost a lot. He told us to right it off as engine gone, but my son still owes $11, 000 on the car note. I should say that my son was late in changing the oil (he has learned the hard way I presume). They said that they ran some sort of cleaner and added oil. My son's vehicle starts but does not go over 40 mph. They also said that everytime they run it they have to clean the camshaft sesnors from I assume from oil sludge at the bottom. I am not a mechanic but I don't want to right it off yet. Thank you!

Hello. Could you please tell me how to check the sensor. I will start there. Hopefully, it's just the sensor. Thanks for the video and your time.

I have a 2007 Lincoln navigator with a 5.4 triton periodically when the engine is warm especially during the summer time I get a P0345 code and the engine runs rough to the point you have to put it in park bring the RPMs up to smooth it out I was told that the timing chain the followers in the cam phasers have been replaced but I still have the same issue. It only happens after the engine has been running for a while more notice volt when you’re backing up in reverse could you enlighten me please

hey I replaced my sensor after getting this error, would I have to reset anything to clear the code or would it clear itself if resolved?

Where does it say the "A" Circuit is Bank 2?

[thutch]

If there was to be a short, would it not blow a fuse? And if so, which fuse?

Where is it located on a 2012 mustang v6?

How much would this repair cost. Worst case scenario

[omertadacode]

Won't start, changed both sensors and cranked once and shut off
