cam position sensor
 

SES code said cam position sensor, intake side. I saw the DIY on the board for the 3.0...I have a 4.4, is the DIY just as easy? Is the location the same? Should I replace both sensors? OEM price quoted is 130 and change, I've read bad stories about aftermarket sensors and would like to stick with BMW parts. Thoughts? Opnions? I replaced the FSR, is the DIY any more difficult for the cam position sensor. Indy cleared the code, when I change the sensor will anything else need to be done?

Thanks in advance for any advice
