I hope it is not intake sprockets

 

IVT codes. And no, the sprockets are mechanical, it would take a catastrophic event to make those go on their own and not have any other codes or failures.

It could an IVT solenoid, crank or cam sensor.

I would reset the codes and see if they come back. This happened to me a while back, years a go, and they have yet to return. I think it;'s unlikely something is wrong since the both came on. They seem to be more sensitive to phase error than say a crank or cam sensor since they trip before, and the cam/crank sensors have yet to.

But in any case, I would say that it would more than likely be the solenoids if the code does come back, though again strange like mine that they both tripped at or near the same time.

 

The engine (VQ35DE) have two camshaft sensor

P0011 (Camshaft Advanced Timing Bank 1)
p0021 (Camshaft Advanced Timing Bank 2)

Replace the two Camshaft Sensor
Both on the driver side
Both with rubber O ring
Both with green tab on the Connector ( to remove it PUSH down the green tab and pull the connector)
Camshaft Sensor Bank 2 (near the radiator with angle connector)
Camshaft Sensor Bank 1 (near the firewall with straight connector: need to remove the air filter assembly)

Replace the Crankshaft position sensor (below the engine in front of the radiator: Straight sensor without O ring

Replace it with oem parts.

You must be a Nissan service tech, because that's their mentality.

Way to essentially cut & paste from the FSM.

I'd reset it before I went through all that trouble. As stated prior, I had the same codes a while back, car was fine, codes just popped up, I reset, and they have yet to return, some 30k/2.5 years later.

 

 

Check your oil level.
Number one reason for this code - engine low on oil.

Really.

 

is this drive able for short distances with the 0021 code on ?

 

you are replying to a 10 year old thread, first check your oil level, then follow the code, if it says crank then replace the 3 CPS sensors. i wouldn't recommend driving with that code, the car may literally shut off while you are driving with no indication or hint of it prior to doing so, putting you and the car at risk.

 

Would the coolant leaking have been the cause of sensors being damaged ? Or im on an 03 reaching about 145 k is it about that time ?

 

you could have oil leaking past the cam sensor o-rings and getting to the connectors, that's what happened to me.

 

Thanks for the input ok so after doing a bit of research and teaching a few videos , I apparently got the 0021 code meaning the sensor closer to the front near radiator which is where most of the coolant leaking was near. . It's a 2003 with 145 k . . So I maybe just swap out the front one only ? or just do both while we're here ? also the guy who responded to me said there is 3 sensors and the man in the video says there is 2 sensors.. so yeah I'm sort of confused now. .

 

two cam sensors and one crank sensor.
​​​​

 

​​​​​​Awesome ok now I just gotta find some info on where that crank one is at thank you bro
That clarified a lot since the part I ordered comes in a 3 pack.

 

the crank sensor is on the oil pan where it meets the transmission bell housing, on the radiator side of the engine.

where did you order them in a 3 pack from?

 

From eBay . User said it was located in. Corona, CA so they should be getting to me pretty fast and w free shipping
Also yeah I saw a video for it late last night, I'll have one of my boys who is a little more handy handle this fix though. Not crazy amount work but I'm a noobie at this car stuff.

 

I usually avoid buying engine electronics from ebay, you never really know what your getting. Rockauto has been my go to for the past 8 or 9 years now.

 

I guess I kind of gave into impulse since I haven't been on the road since Feb 18th when my fuel pump gave out. . So basically when I was barely starting to drive this after the fuel pump now I have this code appearing and the RPMs feel very off . My dad has ordered a lot from eBay in the past and he's never had any issues on his older Tacoma.. I will for sure post when i get the part and this worked on Friday afternoon. Thank you gentlemen for all the positive input

 

yea for any major electronics these old cars prefer OEM, i had evap code issues and dorman parts did not fix it, i put on OEM and problem went right away.
CPS sesnors i replaced with napa , problems came back in 12 months, replaced with OEM and never saw the problem again.

 

I just received my Crank sensor a 1/2 hour ago. Hitachi. I understand Nissan is OK with using this brand. I will be replacing this week. I've replaced 2 cam sensors, light came back. Same P0011 code. Hoping this works.

 

my car is at 348,XXX miles and it still has the same crank position sensor that came with the car when I got it in December of 2012 with 175,XXX miles on it.

I'm guessing it must be OEM. I just keep it clean as well as it's mounting surface.

 

Part says OEM Nissan Motors Ltd on the packaging. . I should be okay right ?

 

Good to know, I guess will see..........

 

Ok my bad for taking so long to get back after the fix so anyway the whole process went smooth ive driven it about 300 miles since the Crank sensor replacement, and about 360 total after my fuel pump replacement and everything is feeling good and the RPM thing isn't acting up.

I hope These non official but OEM " still on the package w Nissan logos and LLC or whatever they looked and felt exactly the same as the original ones as far as sturdiness, I was about to weigh them and see if they were the same exact weight but I was just trying to stay outta my mechanics way when he was here working on the car . .

SIDE NOTE: Is Anyone Knowledgeable with all the T5 bulbs in the interior.? (Cluster , Climate ctrl panel , Glove / Ash ) I've manged to literally change out everything to Ice Blue LEDs except the damn Shifter light. What is the best way to access it ? I followed instructions from a different website but it felt hopeless reaching it following those directions.. so does anybody got advice on this or can maybe refer me to a thread on here..?

 

I don't understand why on Rock Auto there are 3 cam position sensors and 1 crank position sensor. All 4 sensors are unique in design. I think those combo packages on Ebay are legit. I don't know for sure if there the same as member from East Los Angeles that bought from a seller in Corona, which is east of LA by 45 miles or more. The parts look legit, at least in the pictures they do. There a lot cheaper than Rock Auto.

 

at that price those 3 "oem" sensors are most definitely counterfeit.

 

stay off eBay and Amazon when it comes to engine electronics and fueling

there's only 2 cam position sensors, one for each intake cam and 1 crank position sensor which reads the flywheel...

 

Definitely fake as F***
Or the old original defective units that were TSB'd off the Stealership shelves and someone bought their old stock inventory and is now selling you trash for you to crash! Beware! Rockauto has Hitachi and they are the real deal!

 

definitely stick with Rockauto. I remember years back hearing about eBay and Amazon having counterfeit spark plugs lol

 

The price difference is significant but, I've trusted RockAuto for at least 2 decades and told all family and friends forever. I was going to try for just $30/ebay for all three but chose not to. uptownsamv, thanks for all your solid info. Been reading your knowledge for years. That picture shows driver's side, Left and Right sensors on both Left and Right heads of the engine. That 3rd sensor that reads the flywheel has to be a cross section of the transmission, down below. All have rubber washers that can be cleaned, lightly lubed and reused? Clean mounting surfaces really well, alcohol with microfiber towel. I will apply a tiny amount of dielectric grease to all metal to metal contacts/junctions. May clean metal contact points with electronic cleaner before.

uptownsamv, could you clarify, just order all 3 Hitachi [Left, Right and Lower] and I don't need that Denso one under Crankshaft Position Sensor in my first picture above^^^

CMax03, to your point about TSB parts with official Nissan logos:

 

the Hitachi CPS0006 listed as lower in your cart seemed odd but after looking things up that's actually a crank position sensor. for some reason Rockauto has it listed under both crank and cam sensor.

the crank sensor also looks like one of the cam sensors so don't get them mixed up.
