Having problems with your 2004 Nissan Maxima ?
I need to replace my crankshaft sensor, how do i do this?My transmission is jerking on my 04 Maxima and after researching it seem that I need to replace this.
Pull the Diagnostic Trouble Code(s), if any, from the on-board computer and let that be your guide on where to begin. If you aren't familiar with that process, go to Autozone, where they will pull the code(s) for you for free. Other parts houses may do it for free or a nominal fee. The code will provide your starting point. Your diagnosis to date appears doubtful as the true cause of your issues.
Look for a leak in the hoses between the PCV valve in the crankcase and the intake on the motor. A vacuum leak of this type can cause a jerkiness (runs rough) and will make the transmission seem to be malfunctioning because the motor is trying to correct for incorrect air-fuel ratio. Check to see if there are soft squishy or very oily spots on those hoses (would indicate a hole at that position).
