Case Studies : How to fix the P0345 OBDII error in a 2006 Infiniti G35

My 2006 Infiniti G35 Sedan has served me quite well for a number of years, and despite it’s high mileage, been an excellent car for most of it’s life.

With over 200k on the odometer, I guess I cannot fault the Infiniti for acting up recently but I’ve had a difficult time diagnosing it’s current issue. It doesn’t happen all the time, but when warm, the car begins to sputter and misfire and occasionally lurches off idle or with  slight acceleration.

After which time, the check engine light never seemed to light off, but the VCD and ABS lights would stay lit after the car would sputter. After wrongly assuming it was coil related I started testing them, until the car finally threw a code so that I could diagnose it.

And lo and behold, it’s the good ol P0345 OBDII error – P0345 Camshaft Position Sensor Failure A Circuit Bank 2 ; this code indicates that a problem was detected in the camshaft position sensor circuit of bank 2 ( which is the driver side of your VQ35DE).

Case Studies – 2006 Infiniti G35 Stereo Removal

This G35 has the 6 disc changer option from the factory, and it refuses to spit out discs or play discs anymore. Instead of operating, now the unit simply makes an odd buzzing sound and turns off when you attempt to access the CDs.

So removing the G35 stereo is our next step, tools you will need for this install.

  • a plastic panel popper
  • phillips screwdriver

First, locate the shifter ( if auto ) and push down on the chrome clip to access the retaining circlip inside the shifter.

Next carefully remove the golden circlip, and pull up on the shifter knob to remove. Next, use your panel popper ( or spatula ) and carefully unclip the accent bezel located above the 2nd glovebox.

Now carefully run the panel popper ( or spatula ) across the length of the trim piece, take caution as to not break or lose any clips or plastic pieces.

Now with that trim removed, go back to your shifter base and using your panel popper carefully pull up on the lower right panel to pry up the entire base.

Pull up on the entire assembly to gain access to the center console area.

Next, carefully unplug the hazard switch and clips from underneath the shifter base area.

Now undo the 4 screws located around the trim of the lower center console, make sure not to lose the 2 screws that are located towards the front of the car.

Phew! You are halfway there! Now turn your attention to the clock and the top trim above it, using your hands press inwards to release the clips while at the same time pulling upwards. Here is a pic of how you depress the dash and release the clips.

With both clips pushed away, you can now carefully pull away on the top panel.

Now using your panel popper, undo the lower bezel from the clock, pulling away from the face of the clock and towards the back of the car. After getting the bezel loose, simply pull up and away.

Now using your Phillips screwdriver, remove the one screw holding the top radio bracket in. This is located directly under your clock, sorry for the blurry picture.

Move back to the back half of your center console and slide the entire assembly forward, now unclip the side panels and push inward.

Now turn your attention back to the lower center console, and carefully pry upwards and away on the side panels of your center console.

Pull up……

Now repeat the process for the left hand side to gain clear side access to your radio. There are 2 screws holding the bracket in place, that are located under the silver bezel we removed earlier, the 2 other screws are located directly under your radio unit.

The entire assembly should now be able to be lifted up and out of the dash, take care not to scratch the dash when removing your stereo as the clock bracket is rather long and can cause damage if you are not careful.

Now with your stereo removed, you can now service / replace / or throw away as desired!

Best of luck!

Case Studies – Cam Angle Sensor and Drive Belts on a Infiniti G35

My G35 has been driven hard and put away wet by many various members of my family, and just the other day the car threw the dreaded P0340 CAS error. Oh well, I guess I can’t be too upset considering the G35 has over 230,000 miles on it.

What better time to replace my drive belts and freshen things up on my VQ35DE?

Tools you will need to do this job.

Although this job can be performed with the car on the ground, it can become rather cumbersome. Instead we head to the garage and get it up on the 2 post for an easy install.

First disconnect your negative battery as always.

Next with the car raised, undo the 10mm bolts holding the lower G35 splashguard in place, along with the pushpin in the center of the splashguard.

With the guard removed, you now can see the undercarriage and subframe clearly. Locate the 2 tensioners for your drive belt assembly.

Here you see the power steering and alternator tensioner, and on the opposite side of course you see the air conditioning tensioner, shown below:

Now take your 14mm socket and lightly crack the center nut holding both tensioner pulleys tight.

With both pulleys cracked loose, now undo the 14mm tensioner rods that are shown in the first two pictures. Undo the tension slowly until the tension in the belt is loose enough to slip the belts off.

Make sure to remember your belt layout, and that the A/C belt must be put on the car first before slipping the power steering and alternator belt in place.


Unfortunately, before installing the cam angle sensor we find that the dealer sold us the left bank when it’s the right bank we require.
