A P0340 will illuminate the MIL when the computer sees two drive cycles where bank one cam shaft is not aligned with the crankshaft

Therefore, in addition to sensor issues, wiring and connector issues you could also have electrical interference PLUS the gear attached to the cam has spun or is damaged

That being said, here is the information you requested...
I have a 2000 BMW - 5c0e348.gif
furthermore... here are the procedures from my service manual... nothing tough at all!

Removal & Installation (3-Series - E46)
To remove intake camshaft sensor...
Remove intake air filter housing.
Remove VANOS adjustment solenoid valve located next to oil filter housing.
Disconnect sensor electrical connector.
Remove sensor screw.
Remove sensor from cylinder head
To install, reverse removal procedure
Replace sealing ring as necessary

To remove the exhaust camshaft.
Disconnect exhaust camshaft sensor connector on front of cylinder head. Remove sensor screw. Remove sensor from cylinder head. To install, reverse removal procedure. Replace sealing ring as necessary


if you need anything else just let me know!

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

Possible causes- 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

Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code.

I have the code p0340 for slip n tcs is telling me is a sensor but it show2


I am not sure what "slip n tcs" means but on the 2005 nissan maxima the code P0340 is for the camshaft position sensor circit on bank 1, which is in the rear of the engine compartment. Code P0345 is for camshaft position on bank 2, which is in the front of the engine compartment. The images show the Cyl banks and a cam sensor.6_29_2012_3_38_07_am.gif6_29_2012_3_40_48_am.gif

P0340 OBD-II Trouble Code - Camshaft Position Sensor Circuit Malfunction

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
* a wire or connector in the circuit could be grounded/shorted/broken
* the camshaft position sensor may have failed
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required



P0133 OBD-II Trouble Code - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
* Check and fix any exhaust leaks
* Check for wiring problems (shorted, frayed wires)
* Check the frequency and amplitude of the oxygen sensor (advanced)
* Check for a deteriorating / contaminated oxygen sensor, replace if necessary
* Check for inlet air leaks
* Check the MAF sensor for proper operation


Hope this helps (remember to rate this answer).
