Mk4 golf 18t code po340 camshaft sensor a circuit bank 1 or single sensor circuit malfunction changed cam sensor still the same thought sensor faulty got another one still the same

code to 0340 refers to cam shaft (CMP) sensor A , bank 1 ---circuit malfunction===causes -- wiring--- CMP sensor --- ECM
check all wiring and connections to the sensor , replace the sensor

you are dealing with 2 issues
code p 0325 refers to knock sensor (KS) 1 bank 1--circuit malfunction ====causes ---wiring ---poor connection ---KS
code p 0340 refers to camshaft position sensor(CMP) sensor A bank 1--circuit malfunction===causes wiring--- CMP sensor ---ECM
code p 0344 refers to CMP sensor A bank 1 --circuit intermittent===causes --wiring --poor connection---CMP sensor --ECM
check wiring and connections before replacing the CMP as the wiring may be the cause of all the codes

bad news
those is the main /cam sensor
if fail hard, engine stalls, no spark
which engine, 4.0liters?

cam single dead or dropping out 1 to 10 times
it does give early warnings. (can)
check wires to it.

Wiring.
Vehicle speed sensor (VSS).
Engine control module (ECM).

P0345 = Camshaft Position Sensor "A" Circuit Bank 2P0340 = Camshaft Position Sensor "A" Circuit Bank 1 or Single Sensor

code p 0320 refers to crank shaft position sensor (CKP)/engine speed (RPM ) sensor---circuit malfunction====causes ---wiring---CKP/RPM sensor ---ECM
code p 0340 refers to camshaft position sensor (CMP) sensor A bank 1---circuit malfunction===causes wiring---CMP sensor ---ECM
following engine work , it is always best to check that all of the harness connections were assemble properly
check for broken wires during the work

P0340: Camshaft Position Sensor A - Bank 1 Circuit Malfunction

- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery

3.3 and 3.8 front of the engine near the timing chain look down between the thermostat and the alternator. It near the motor mount. 3.0 engine in the distributor.
