Any Nissan experts here? 2002 Sentra

[89VWdieselGolf]

I've got a 2002 Nissan Sentra 1.8L

After driving for about 15-20 mins it will stall. Wait 5-10 mins before it'll restart. Drive a bit longer, dies again, wait 5-10 mins before it will start again. Repeat.

Code is P0340 (Camshaft position sensor)

I've searched google, and it seems everyone replaces the camshaft/crankshaft sensors (both sensors are same part number and nissan recommends replacing both at the same time) and doesnt fix the problem.

Nissan had an ECU foam recall (R87) and it has been done on the car.

Little backround. Car was purchased new by my mother, always dealer maintained, 397,000kms! Because of this problem they quoted her an ECU, cam sensor, crank sensor, o2 sensor $3000 so she bought a new altima and gave me the sentra. I want to see if i can get it running because it is in really good shape.

Anyone here delt with this first hand. Seems there is alot of other people asking this question when searching google but no one comes back to post the solution.

thanks!

Just a shot in the dark, but maybe a bad ground?

If not that, it's clearly just a result of your mother chirping third constantly.

Do the B15s suffer from clogged IACV as the GA15DEs did?

could, but why would waiting 10 mins (letting it cool down) make a better ground?

although, could be the second explanation

[GolfTango]

I'd just start with the smaller stuff.

Clean the MAF and throttle body. Then pop off the IACV and clean it well with tb cleaner. Then perform the idle relearn procedure. Maybe check the function of the PCV. Also check the connection of the ECM. Could be some fretting. Use a little dielectric grease on the connectors and reseat it.
But it may well just be the camshaft sensors are toast.

Then perform the idle relearn procedure.

Could you please elaborate on the procedure?

[89VWdieselGolf]

thank you.

I'll try that stuff.

Any chance it could be something like a coolant temp sensor? Reading wrong when hot, let cool and runs fine again.

maybe try that if the ecu reset procedures don't work and see how it goes

Nissans of that vintage were notorious for crankshaft and camshaft sensor failures. A missing signal from either one will cause the engine to die and/or not start. I used to see this exact problem all the time a few years back, when the affected cars were just coming out of warranty and landing in my bays. Nissan has revised the parts several times over the years, and I believe they finally got it right because it's been a long time since I've seen this issue now.

Start by replacing the cam sensor.

And they were heat/drive time issues also?

This may be unrelated, but I have a 2004 and whenever there is anything plugged into the 12v outlet (either one) the ECU goes crazy, the engine revs and transmission acts up as well.. So my solution was to unplug my phone charge and it works just fine. So I came here to ask if there's anything plugged into your 12v outlet.

A friend of mine has a 2004 SER and does the same thing as mine.

[89VWdieselGolf]

nothing is plugged in. Thats a good one though

I've ordered a cam sensor, and will try reseting the ECU, pedal, tb, ICV.

[Anony00GT]

Yes. Resistance in the hall sensor increases with temperature.

It's not uncommon for hall sensors in general to give faulty signals as they get hot.

how did she trade it in and give it to you?

whoops, didn't mean to write that... she bought a new car, and gave me it*

**UPDATE**

Replaced the camshaft sensor; $33 part from the dealer (didnt do any of the relearns)

Went on a 35km road test - No issues
Went on a 75km road test - No issues

I'm going to drive it to work and back a few times and see what happens, but knock on wood, i think that fixed it.

Working in a dealership myself, i have a feeling the tech decided "This car has 400,000kms on it, throw everything at it that it could be and scare her away"

thanks for everyones input. I'll update more once i'm sure of a final verdict

Dude. Thanks for updating. So often we get no resolution.

I hope it worked.

Good deal!

And not a single post asking if it chirps third!

Yes, I should have mentioned that. The dealer is the ONLY place you should get this sensor from. No re-learns are necessary after replacement.

Glad to hear it's resolved

We don't even know if it's a stick...do we?

Nope, it's an auto.

If it were a stick i'd want to turn it into one of these:


old Nissan Sentra spec series we had in Ontario in 02/03

Nissan sprung thos sentras so soft even a lil wind can make the suspension move

They aren't bad for getting aroudn i must admit
