Fix for Mini Cooper One error code P0343
Hello,
This is just for reference for Mini Cooper One owners (1.6) as I couldn't really find a specific fix on the internet for this error code so
hopefully this may help others out in the future who search for this error code and need a solution.
Had the engine warning light come on in the girlfriends Mini Cooper One 1.6 2010. I plugged my OBD2 code reader in and it detected "p0343
Camshaft Position Sensor "A" Circuit High". I suspected it was the camshaft position sensor which was faulty so picked another
genuine one up from eurocarparts for around £30. The issue turned out to be this which was good. however I want to point out some of the issues I had
and the solutions which may speed up the fix for people and reduce the gray hairs appearing.
I couldn't figure out which sensor was faulty to start with so i used a multi meter to check the voltages. When looking at the connector into
the camshaft position sensor from the front with the locking clip on the top the first pin on the left is earth, the middle pin is the signal
connection and the pin on the right is the +5v. When checking the signal connection should fluctuate between 2.2v and 2.7v which the faulty sensor
didn't. This is how i figured out which was faulty.
The other problem i had was clearing the code. my software requires the code to be cleared with the ignition on but the engine off. With the mini
cooper you have a push button start. and having the key in with the engine off doesn't mean the ignition is off I found. This caused me to doubt
that the sensor was the fault as the code appeared to keep flagging up. however I cleared the code by starting the car then stalling the engine which
then kept the ignition on. This enabled me to clear the code and sort the problem.
The crankshaft sensor Bosch part no. is 419120057
Pictures for referance below. (I grabbed the image from www.pelicanparts.com to indicate the sensors and for refernace)
The intake (inlet) camshaft sensor is located on the left rear of the cylinder head (green arrow). The exhaust (outlet) camshaft sensor is located at
the left front of the cylinder head (red arrow)
Hope this helps some people out.

To get the ignition on just hold the start button down without your foot on the brake pedal.

It always says key on engine off when clearing codes but I yet find a car that codes wouldn't clear key on engine running, in any event the code
would clear itself after a couple of drive cylcles.
