Hi. It could be the cam adjuster or the Timing chain stretched.

SOURCE: mk4 golf 18t code po340 camshaft sensor a circuit

The system will erase the fault code when the system senses that a component is functioning within three starting cycles. Even if you replaced the cam sensor three times it will store the same code if the wire harness or connector has is not supplying data from the magnetic pickup to the ECU. Until you have isolated why it doesn't read the sensor you'll be stuck with a no start situation.

P0340 - Cam Timing

SYMPTOMS/CONDITIONS
of a mistimed camshaft system (all must apply):
  1. Camshafts have previously been removed from the engine.
  2. Engine runs rough.
  3. Vehicle sets P0340 (camshaft sensor code).
  4. Camshaft sensor has been checked with a known, properly operating camshaft sensor.

CORRECT:
The diagram in the manuals should show the timing marks on both cam gears to be on the blue timing chain links.

HELLO, I HAVE TROUBLE CODES PO330,PO340, ON MY OBD2 READER WITH THE MAINT LIGHT ON IN 96 BMW Z3 ROADSTER 4CYL., PO330 IS KNOCK SENOR, PO340 IS CAMSHAFT POSITION SENOR, I WANT TO KNOW HOW TO FIX THEM BOTH....


The Cam Position Sensor is a common item to fail. However, the cam positioning mechanism can fail too giving that code.

There are two sensors and the Exhaust Cam Sensor is most common to fail. I always replace both.
Te CKP's are on the top front of the engine next to the cylindrical operation solenoids.

Knock sensors fail too and need checked or correct feedback to ECU with a scanner.
Find a shop near you at http://www.iatn.net/shopfinder/

These engines require regular oil changes with quality synthetic oils and OE filter....not a FRAM or WIX !

Buy only BMW sensors ...aftermarket have high failure rate.

DTC - PO340, PO325


My Nissan micro 2004 model just stopped in the middle of the road one day then the engine management light came on, anyway took it to my local garage TWK Thomas who said it was a cam shaft sensor problem. OK so sensor was put on, engine management light went off for two days only. So went back to the garage they said that another sensor should be fitted on the opposite side. And then the problem should be rectified, but i had given the £160 for this problem to be fixed the first time. I decided it was time to take it to another garage Nis Tec they put it on the computer and a code po340 came up would this mean another sensor or the cam chain has stretched please help. ...claire

I have a 2000 chrysler concorde that the engine light just popped on - the error codes are po302, po420, po340


P0302-cylinder #2 misfire detected
P0420- catalyst efficiency below threshold bank 1
P0340-No cam signal at PCM.
The Cam sensor most likely needs to be replaced first. Clear the codes after that and drive and see what comes back on.
