06 bmw 525i codes p0174, p0171, p1338, p0340, p0365, and p1315


codes p 0171 and 174 refer ti system too lean
codes p 0338,340,365 refers to crank. and can shaft position sensors
code p1338 again is camshaft position sensor
code p1315 again is camshaft position sensor
too lean can be from fuel pump pressure too low
and position sensors can be wiring , connections sensors.
Involved in all these , one of the possible causes is the ECM
IF it is possible get a serviceable replacement ECM unit and substitute it first as there is no point in replacing all the rest if the ECM is faulty
could be water in the connections , corrosion etc
it is always suspect when so many different codes suddenly appear at the same time

P0340 code


DTC P0340: Camshaft Position (CMP) Sensor Circuit
P0340 ?€¢
The ECM detects that the starter is commanded on and the engine has been cranking for more than 4 seconds without a CMP sensor pulse.


OR


?€¢
The ECM detects that the engine has started, but did not received a CMP sensor pulse during the first engine revolution.


OR


?€¢
The ECM detects that the engine is running, but does not receive a CMP sensor pulse for 800 of 1,000 engine cycles.


The 4X camshaft position (CMP) sensor circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, low reference circuit, and an output signal circuit. The CMP sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 4-tooth reluctor wheel attached to the camshaft. As each reluctor wheel tooth rotates past the CMP sensor, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The sensor returns a digital ON/OFF DC voltage pulse of varying frequency, with 4 varying width output pulses per camshaft revolution that represent an image of the camshaft reluctor wheel. The frequency of the CMP sensor output depends on the velocity of the camshaft. The ECM decodes the narrow and wide tooth pattern to identify camshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses CMP sensor output information to determine the camshaft relative position to the crankshaft, to control camshaft phasing, and for limp-home operation.
You need a cam sensor or have wiring problem !

Changed the camshaft and crank sensor now getting a code p0340 no camshaft reference signal at PCM for my dodge durango 2000


code p0340 refers to camshaft position sensor (CMS) A bank1--circuit malfunction===causes wiring---CMP sensor ---ECM
IN replacing the sensor there are air gaps to rotor to be adjusted and other items listed in the manual that have to be check out .

2001 jetta vr6 cranks but won't start have fuel and spark replaced camshaft sensor, new plugs valve cover gasket got code of PO343 and PO740


code po740 refers to torque converter clutch(TCC) solenoid-circuit malfunction==causes --wiring--TCC solenoid-ECM/TCM
code p0343 refers to cam shaft position sensor(CMP) A bank1-high input.==causes --wiring short to positive--CMP sensor---ECM. check which cam sensor you replaced and check the wiring connectors. use a code reader to reset the cpu when finished

No spark or fire to plugs


Sounds like a bad crank position sensor or a bad camshaft position sensor.... If the sensors can't tell the ecm where the position the crankshaft or camshaft is, the ecm won't know when to send a spark. So the ecm won't send any spark.
