I recently purchased a 2013 Mini Cooper S with 81k miles on it. I've been struggling to fix the P1338 code for over a month now. Whenever the code appears, the car is slow to start and runs at reduced power. I've tried-

New camshaft sensor
New timing chain tensioner
New timing chain/guides/cam sprocket
New upstream O2 sensor which still reads as very low voltage (around 0V) after replacement but everything electrically seems fine.

Absolutely NOTHING has solved my issue as the code comes back before I can even get the car down the street.

Have you swapped out the VANOS solenoids?

 

That's the only thing I haven't tried yet. I'm going to take it out and clean it up today and see if that works

 

Just pulled out the solenoid and it seems to be in the process of failing. Reads as 7.5ohms (normal range I saw was 8-13). So I'm going to order a new one today.

 

Went ahead and swapped the old one out with a brand new one and still no luck on getting rid of the code.

 

Hello.
Wondering if you have any update?? Were you able to get rid of the code?

 

I was able to fix P1338 with "reset variable camshaft timing adaptation".

 

hello
I am getting the same code after timing chain and stem valves replacement. what is that camshaft adaptation?

 

Are you absolutely sure the mechanical timing is dead on correct? If not, double check that first.

 

This should help you.

I don't see a DTC index in MItchell1, but an internet search indicates your P1338 codes is for a camshaft position sensor (not sure if its for the intake sensor or the exhaust.) Both sensors are 3-wire Hall Effect sensors. Pin 2 (yellow wire) on both sensors is the signal wire. The first step would be to connect a lab scope to the signal wire and look for an abnormal wave form. If there is no wave form, then you would need to check the 5 volt reference circuit from the DME to the sensor and then check the sensor ground wire. Pin 1 is the 5 volt reference. With the connector disconnected from the sensor, you should see 5 VDC on that pin. With the connector reconnected, you should see the voltage drop. Also with the connector connected to the sensor, you should not see any more than 300 mV on the ground circuit pin 3.

As for your upstream oxygen sensor, the upstream sensor is a 5 wire wide band sensor. You don't look for voltage on a wideband sensor like you would on a narrow band sensor, you look for current switching. Keep in mind current goes negative with a rich mixture and positive with a lean mixture (opposite that of a narrow band sensors voltage).
