Ran diagnostics bc "service engine soon" ", "slip" and "VDC Off" lights were on. Came up with Trouble code P0340 which means there is a problem with the camshaft position sensor. There was a recall on most 03 coupe's but ironically mine missed the recall dates by about a week. I was wondering if anyone has any experience with replacing the camshaft position sensor. The sensor is only 60 bucks, but naturally the dealship wants 350 to repair, and my local repair shop is asking 200.

SPECIFICALLY- where is the sensor located? is this a manageable job? I think there may be information in the Engine Control chapter of the Service Manual, so I may have to check that out.

The recall language calls for replacement of the camshaft sensor and possibly the crankshaft sensor (if the camshaft doesn't work).

Thanks- any advice is appreciated

 

Took my mechanic 5 minutes to replace...he actually teased me and said he would need the car overnight and while he opened the hood to "inspect it" siad...you're done gtfo.

there are 2 sensors and we decided on buying the right side sensor because it seems to be the one that breaks the most.

 

yes my old 03 had the same problem also, the passenger side camshaft sensor broke and the same light appeared.

 

did you maybe SEARCH the DIY section? im pretty sure i wrote the DIY for this. like a million % positive i did.

anyway depends on if it is bank 1 or bank 2 i believe bank 1 is the drivers side easy to get to. bank 2 is the pass side you have to take the upper and lower plenum off to replace both parts are about 140 ea. from the NISSAN dealer more from infiniti and you can take the plenums off in about 10 mins all in all about 25-30 mins of work you can do in your driveway.

replace them both get it over with.

 

I search the DIY setion but I'll search it again in case I over looked it. Thanks guys...founded the DIY snakes1021 I appreciated. https://g35driver.com/forums/engine-...n-sensors.html

 

You don't have to remove the plenums if you know where you're going, but its a tight fit. Taking the plenum off will save you a likely headache if you haven't done this before.

 

damm im going thru the same trouble right now.. but gonna get it fixed hopes by next week

sensor- $65 By Auto parts Warehouse

LAbor - $$ - By R&J

driving the G35 smooth and happy - Priceless lol

 

On the rear of each cylinder head.

 

same **** happened to mine. I bought the sensor at cerritos infiniti and swapped it out. I read somewhere that the little O ring on your new sensor must be slightly oiled before you install it. Either way, i took care of it, super tight fit but it got done. Let me know if anyone needs help in socal

 

Thanks, you were right about the recall for the 03's. So, how can I find out if mine will qualify? I think it's a 6/02 production date.

Can anyone for certain advise which sensor "Bank 1" is located? Passenger or driver side? Thanks!

 

There's a thread with DIY cam sensors says easy version in the title. All these questions are answered. A reminder, do not buy non OEM cam sensors

 

Does anyone know how to separate the sensor from the green clip for the camshaft sensor? I can not separate them? HELP!

 

It has been awhile, but you push the green clip "in" then pull them apart, it is hard to explain but it is not like other clips when I say push it in more like slide it toward the sensor. They can be tricky but that is my best description of how to do it.

 

So I replaced both sensors and my car still takes a while to start. I originally had the P0340 fault, now that one is gone and I'm receiving a P0345 fault, service engine soon , VDC and SLIP lights. I don't know what is wrong with this car
