Alright, so I've searched the multiple threads on this subject and still have a couple questions regarding it; mainly because the part Autozone told me isn't mentioned a whole lot in these threads (it was a $189.00 part that looks nothing like the camshaft sensors). In another post RICH@GRUBBS responded with what's below, and I think this is what Autozone was trying to make me buy:


My check engine light has been on for the past two weeks and it currently idles at 1k-1,200. Today it just stalled while driving and it took me a few tries to get it going again....after I got home I stopped/started it a few more and it had trouble turning on as well. This was the best response I saw regarding the P1078 code:


2 years ago I replaced 23731-6J90B (straight sensor) on the passenger side, but now realize we have 4 sensors.

So if I now need 23731-AL61A (angled), do I get two or just one? For driver or passenger side?

What about the Solenoid Valve Timing Control (VTC), is this unnecessary to get, and I just need the angled sensor?


Thanks in advance for any help

 

These sensors are tricky. if you replaced 6J90B, you just need to replace the driver side as mentioned, and you need to replace the sensor that is under the car. That's right there's a third sensor underneath. The fourth sensor is deep in the engine, you need to get below the fuel rails and it's annoying. Then you have to replace the harness that goes to that sensor as well. Try the other 2 you haven't replaced yet, then do the last one if all else fails.
the VTC is more rare, and again, much harder than the 3 position sensors.

 

Here are the 3 position sensors


The other sensor I got from z1 because it came with the harness that i hear can cause problems. But again, this would be something i would do after the 3 position sensors are replaced.

 

....another day another issue. So my car will take a couple of seconds with the key turned to turn on, and the VSD and REV light are now lit.

Thanks UR2EZ, that really helps and hopefully I can sort this out myself

So here's my question: I've read 23731-6J90B and 23731-AL61A were the only two sensors and there are two on the driver and two on the passenger side...but you have 23731-AL60C and some other one with a harness as the other two I need. Am I following this right? Because I thought I was supposed to buy an angled sensor for the passenger side....

So now I need the drivers side (angled) and another one under the car (23731-AL60C)....if so, where's this third one located?

 

05 6MT, so rev-up motor

....and I meant to say the SLIP was lighting up earlier, not the rev

 

for the same engine.. on the driver side (Bank 2), the EVT sensor is straight and throws the p1084 code...

 

If he's throwing a code for exhaust valve timing he obviously has a rev up haha. Not the first thread I've seen on the subject of evt lately... DE ftw!

 

Thanks for the help everyone

I'll get the angled sensor for now and go from there

 

Alright, so I replaced the driver side angled sensor (bank 1) and it fixed the rough start and the VSD and Slip light went off, but the Check Engine light is still on. The idle is still a bit high at 1,000 - 1,200 RPM instead of the normal 750.

It seems like people have different takes on where these sensors are located also

.......looking at the picture, I see only one on each side and Bank 1 should be the drivers side, right?

.....isn't 23731-AL60C the same as 23731-AL61A (an angled sensor)? And if you're correct, where is this third sensor located under the car?

Thanks for the help as always

 

Bank one is passenger side, third sensor is on the bell housing. Jack up drivers side, you can get at it with just that side off the ground. It has RTV on it, I would re-RTV (ultra gray) permatex.

 

Ok, thanks for the clarification on that pic. Really appreciate it

I'm doing my rotors and pads this weekend so I'll locate that third sensor then.

So I'll buy 23731-AL60C it sounds like.....but again, isn't that the same as 23731-AL61A?

 

Are there any common issues with these cars? Im looking to buy one soon and I've never owned an Infiniti before. Any advice would be appreciated !

 

I know I found several videos on youtube with common issues and even some likes and dislikes videos from people that own them. I am sure there is a list here somewhere as well. I have had my G35 for about a week now, and in spite of a couple of issues I really love the car. Happy hunting.

Yeah a simple google search of "G35DRIVER vehicle common problems" with the year and style of your car should return a few hundred results.

I also strongly recommend you watch this short video on forum ettiquette.

 

What is the part number to clear code P1078? I think the code refers to Exhaust Valve Timing Control Position Sensor Bank 1, but I just need the exact part number. There seems to be so many different part numbers that looks like the part I need. If it's it's bank 1, then the sensor should be straight and on the passenger side, right?
