  • My 06 maxima was having problem in driving and starting when warm up
    little. Code was 0345. Changed the camshaft sensor (rear, that's what
    they call it I guess there is another one at front as well, are they
    called bank 1 and bank 2?). Problem is still there now getting codes
    0340 and 0345. Now confused what to do, I mean no point spending until I
    know where the problem is. Does it mean the other sensor is replaced
    wasn't reason? Looking for your suggestion on this. Thanks

  • There is a chance that the wrong sensor was replaced, but regardless which sensor was replaced, the correct one or the wrong one, it is highly recommended to replace both sensor, and to use factory OEM sensors. I have try many with aftermarket sensors and most of the times the light comes back.

  • I have a 06 Nissan maxima SL I replaced the camshaft position sensors and put a new connector on but its the black and green connector the original connector was all green but both were made for my Nissan.
    so my question is what sensor does the black and green connector take?

  • The difference between the connectors is a tab (groove) inside the connector, which prevent connecting the wrong connector.
