2011-2017 VW Jetta 2.0 liter P0340 / P0341 camshaft position sensor replacement

[@kennethmcdaniel7796]

Got one ordered. Replaced crankshaft position sensor and it worked great for 3 weeks then failed to start in grocery parking lot. Fifteen minutes later it started up fine. Same problem I've had every since i bought it.

[@Teds_Garage]

These cars with all the computers and sensors can be aggregating.

[@DKGARAGE_FL]

Because the pulley is literally cutting the sensor. if you hear something hitting, is that. so, or you have to replace the pulley or try to figure out where the pulley is touching the sensor.

[@franka6680]

I replaced mine and it still doesn’t turn on. It does the same click noise it did before e

[@DKGARAGE_FL]

@@franka6680 I notice that noise when I reassembled the pulley (I been doing timing belt). And the noise come off when the sensor broke up.

[@franka6680]

@@DKGARAGE_FL I was told it could actually be the starter. Since the car won’t start and the sensors can’t compute any cam rotation when you scan it it’ll give you a cam position sensor code. But ima try to see if this is true

[@gregspreeman2032]

So, we have a 2012 VW Jetta S, 2.0. It will stall out while at slower speeds. What is more likely, a camshaft sensor or a crankshaft sensor? Already replaced the coil pack.

[@Teds_Garage]

Greg, are you getting any OBD2 codes? Those sensors are more likely when you’re having a misfire. Does it run fine at idle? Just coming off idle it stalls? A 2012, so probably lots of miles. Have you checked fuel injectors, try fuel injection cleaner with only 2-3 gallons of gas in the tank (makes it more concentrated). If it gets better? Do this several times. Maybe replace injectors (WARNING $$$$). You replaced the coil pack… did you replace plugs and wires? I’d also look at cleaning the intake and sensors… the computer is making fine adjustments all the time, so even the O2 sensors on exhaust adjust the fuel at the injectors…. And will make the engine run roughly and lose mpg…the catalytic converter will get red hot and exhaust is stinking… So just a few of my initial ideas… greg let me know how it goes..take care.

[@thoeuthsrey4494]

When I first bought my used 2013 Jetta it was having the same problem. It will stall out when slowed down to lower speed. Ran fine at higher speed and idle good. I replaced the crankshaft sensor and never got the problem again.

[@FOOTZ_213]

@@thoeuthsrey4494I had a bad Key Fob that set off the immobilizer which caused the same issue

[@thoeuthsrey4494]

How did you diagnose the bad camshaft sensor? What were the symptoms?

[@Teds_Garage]

Engine was skipping and my son replaced the plugs, wires, coil pack and it was still missing. We replaced the easy (and less expensive) parts first.

[@Teds_Garage]

The misfire and running poorly even after replacing the plugs, wires and coil pack.

[@boostg20able]

I watch it and how did you tighten that tensioner

[@chronickruk7849]

My 2011 2.0 s just completely turned off when I was in traffic and would start back up just crank but no start can it be because the camshaft position sensor??? I already bought it but don’t wanna waste time if it could be something less

[@Teds_Garage]

Sound’s more like the crankshaft sensor for no start…. Camshaft might also be bad too, but it would probably still start and just run poorly.. Good luck 👍

[@crashmtz1]

How did you turn the engine to get the mark on the pulley on top?

[@Teds_Garage]

Yeah that can be a problem…. This car is manual transmission so we removed the right front wheel … screwed a few lugs back on and put transmission in gear….and using a pry bar turned the axle…which then turned the engine..

[@kylearredondo5140]

That just seems like so much to do is there and easier way?

[@kylearredondo5140]

Ima try it though

[@kodab928]

Will a bad cam sensor cause a no start?

[@Teds_Garage]

It could… cam sensor tells computer when to send signals to the coil pack. So older engines had points and a distributor cam lobe to signal the spark. This modern engine uses cam sensor and crankshaft sensor to signal timing (and adjust timing when running). You may have other problems though… see if cam belt broke (look behind the plastic cover if it’s turning), if you are getting spark at the plugs (also consider coil pack), with plugs out are you getting compression (if it’s a mechanical failure)?, etc.. I had one car with security issues … when the key was inserted it was supposed to disable security… the same key that had worked for years… the engine still turned over but wouldn’t start.. You would think security would disable the starter, but no…😣 So it could be a lot of things and can be hard to isolate… start with pulling the plugs and check for spark.. Good luck..👍

[@Teds_Garage]

Sounds more like a crankshaft sensor for no start condition. But it could be the camshaft sensor.

[@crashmtz1]

Also thanks for the info. Dealing with this right now. Great info

[@crippledanasian5822]

Is the mark on the bolt important or not as much as the marks on the gear/belt????

[@Teds_Garage]

The gear is the only mark that is important. The belt can be moved around so don’t use marks on the belt for reference. The mark on the cam gear must line up with the alignment mark on the metal back plate. The engine must be at TDC (Top Dead Center) on #1.

[@adrianromero6454]

I have a 2013 2.0l S Jetta n my car just won’t turn on. The belt on the alternator turns but not the belt on the camshaft. Sometimes it turns though. I replaced cam sensor like you did n nothing. Will it be the crankshaft sensor. I got p0016 code then p0343 code once I replaced the cam sensor

[@Teds_Garage]

If you are cranking the engine with the starter and the camshaft belt is not moving… sounds like you stripped the camshaft belt… that belt has to turn continuously when the engine is turning. It has ridges on the bottom and they could have been stripped off… sounds like you may need to replace the camshaft belt…

[@Dana-ro5gj]

@Teds_Garage what codes/ problems where you have that you decide to replace this

[@Teds_Garage]

@Dana-ro5gj .. After getting the ODB II code P0340 .. which P0340 is an OBD-II diagnostic trouble code (DTC) that indicates that the powertrain control module (PCM) has detected a problem within your Jetta’s CPS circuit .. caused by an issue with the wiring harness going to the camshaft position sensor (CPS) or the camshaft position sensor itself.

[@franka6680]

What side does the cam bolt rotate? Is it the same lefty loosy righty tighty?

[@Teds_Garage]

Not sure on your first question what you are asking… yes lefty loosely…

[@franka6680]

@@Teds_Garage I figured it out. So I did the sensor. Finished the job codes never came back but the car still didn’t start. After a few days my friend got a second opinion and was told her engine was seized which to me makes no sense cz it was running before it went bad

[@Teds_Garage]

@@franka6680 engine is seized = will not turn over. So if you are getting the starter to turn the engine it is not seized. If the crankshaft is turning then it is not seized…. Now it could still have a more serious problem but not seized.

[@pysof]

Would a bad camshaft position sensor cause poor fuel economy? My car is giving 6-7km per liter and OBD2 scanner showing P0343 code.

[@Teds_Garage]

It will misfire and have less power… so yes.

[@thepicklefish]

Is there a way to test it before replacing?

[@Teds_Garage]

Maybe with ohmmeter/multimeter, and a VW garage with their expensive computer… Not sure on the pin out though but if you have a oscilloscope you could see the signal….

[@thepicklefish]

@@Teds_Garage thanks for your input. I got someone to crank it for me while I inspected and the crank was turning but the cam was not. Pulled timing belt and the teeth on the belt had broke off. New belt and water pump and am good to go!

[@Teds_Garage]

Glad to hear you got it fixed and going again..👍

[@MrOutchini]

How Can I remove the screm without air gun ?

[@Teds_Garage]

Sorry but I don’t understand what you’re asking…?.

[@MrOutchini]

The screw * of the crankshaft because mine turn when I try😅

[@Teds_HomeRenovation]

The camshaft? or the crankshaft? You should be removing the camshaft bolt to get to the camshaft position sensor. Either way I put the car in gear (manual transmission) and it locks the engine. If you don’t have an impact tool, use a tight fitting wrench and tap the end lightly with a hammer…. Don’t get too aggressive. I think they used a “lock-tight” and just a slight tapping will get it to release. If you have an automatic transmission - first try the tapping method above. If still stuck you hold the crankshaft to remove the camshaft gear bolt. This requires a special tool… that fits your crankshaft. VW has different types over the years and different engines so get the right tools. You need to check your auto parts store for if they have the tool and some places will rent/borrow the tool for the day. If not (not recommended) you can use a wrench/wood wedged into the alternator belt to hold the engine…. But be careful not to damage the alternator pulley or belt.

[@KingKing-rg8tv]

I guss it is mtch essiyer to get out the timing belt, may be I am wrong??

[@Teds_Garage]

You have to get the timing belt off the crankshaft (which is difficult) and keep the crankshaft and camshaft in place with the timing markers.

[@KingKing-rg8tv]

@@Teds_Garage Yes for sure it is much easier get out the timing belt of and remove the camshaft sensor

[@Flacidross]

I have a 2013 1.6t Jetta and it turns on then turns off and stalls out. Could it be a cam sensor?

[@Teds_Garage]

It could be…but also many other things… you need to do more troubleshooting… bad gas, water in gas, plug gas filter, etc…

[@kylearredondo5140]

You didn't explain how you were able to rotate the the timing belt and which way to rotate it to get the mark

[@Teds_Garage]

Slowly turning the ignition to start…ie on and off to get the engine close until you can see the mark. Remove the spark plugs and the engine will turn easier…. Turn the engine at the crankshaft to get the markings aligned. It requires a special tool… that fits your crankshaft. VW has different types over the years and different engines so get the right tools. You need to check your auto parts store for if they have the tool and some places will rent/borrow the tool for the day. I didn’t have the tool….so.. Otherwise…Carefully pulling on your alternator belt and don’t pinch your fingers… with spark plugs out it will turn… You should be removing the camshaft bolt to get to the camshaft position sensor. To hold the camshaft/engine from turning while removing the camshaft bolt: I put the car in gear (manual transmission) and it locks the engine. If you don’t have an impact tool, use a tight fitting wrench and tap the end lightly with a hammer…. Don’t get too aggressive…. they used a “lock-tight” and just a slight tapping will get it to release. If you have an automatic transmission - first try the tapping method above.

My car won’t start, and it’s giving me code p0016, I already changed the crank position sensor but still won’t start, do you think this might be the case?

[@Teds_Garage]

If you’re sure the timing belt is good and you have compression. Do you have spark at all your plugs? Coil pack could have died.. and is much more common and easy to replace. If all the above is good then maybe look at camshaft sensor.

[@thenewera-real8474]

Were you able to fix P0016 code I have same issue but mine one starts with a little extra cranking and checks engine light pops up on every start, clear the codes while engine running no issue, restart engine again same code. How did you fix it?

[@thenewera-real8474]

I even replaced the camshaft position sensor still same issue

[@iraklisulakvelidze-b7g]

When driving, the car stops, when I slow down, it stops moving, what could be the fault?

[@Teds_Garage]

It could be many things, from water in gas, to ignition problems or fuel problems… You will have to start somewhere and eliminate possible problems…
