Replacing all three camshaft position sensors either tonight or tomorrow. Never done this before. Looking for advice or a diagram on how to do this correctly. I have purchased two uppers & 1 lower cam position sensor. Any help would be greatly appreciated!! Nissan said this is something we can do ourselves with little or no issues....Is it true I will need to get Nissan to 'reset' so the error code disappears??????? Thanks in advance!!
