P0341 Camshaft Position Sensor Circuit
« January 28, 2018, 06:44:06 »
2012 Hyundai i30 Elite (1.6 Auto)
90k's. fully serviced and only recently out of warranty

I noticed my check engine light very occasionally came on, typically after driving the car a bit harder.  I bought a ODB2 reader and I can see this error.

:link: OBD-II Trouble Code: P0341 Camshaft Position Sensor Circuit Range/Performance

I'm not stressed as it's just an alert saying timing wasn't perfect (plus the fact it only occurs when I hit it hard but I thought I should ask. 

My fuel economy does suck on the car (9L/100) and I have had the occasional hard start issue (push button doesnt start, I need to press it again).  The car is due soon for a big timing belt service soon.

I don't think it's just a broken sensor (unless the sensor is causing the car to have occasional hard start issues).

Any experienced this one before?

Hmm that sensor actually provides important info to the ECU both regarding start and continous running and incorrect info will affect starting and general fuel economy.

How does one typically determine if the sensor is faulty or if the sensor is correct and the timing of the engine isn't correct?

@noes_oh  Have had this with weak CVVT oil control valves. Easy to replace. First, check oil way to the valve is clear (gauze filter can be clogged). More likely to be this than a sensor fault.

Hi @nzenigma just had it checked out.

Came back as I needed a new sensor. 

Do you mind confirming for me what sensors would typically be replaced?

Shop 1 said (who confirmed the sensor needs to be replaced) $320 and replaces the one sensor
Or.
Shop 2 said two sensors need to be replaced and itíll cost $420

Is it two or one sensors? lol

Hi noes-oh,

There is only one cam sensor. However I have never had a faulty one, not that this means they are always ok.
The culprit is usually this baby;  :link: 24355-23800 Timing Oil Control Solenoid For Hyundai Kia 2.0L Valve/VVT Engine | eBay

As you drive, your camshaft will alter its shape and timing position (CCVT) to accommodate the work the engine is doing. This  movement  is done by the oil control valve. It can wear and cause problems, but sometimes it is the oil feed to it that is clogged (at gauze filter). This must be checked.
 If the control valve is not functioning properly, the camshaft does not move correctly and the  sensor , which is perfectly ok, simply records the fault.

So the question to ask your team is which one is faulty and why? And where is the filter?  :winker:

Added: the control valve above just indicates the type of device, you will need to get the correct one for your model.
