P0340 -- Cam Shaft Position Sensor
A friend has an '00 323 that has stalled twice in recent weeks, once today,
and the Service Engine Soon light comes on during the event, but then goes out again and remains out. She pulls to a stop sign, waits her turn to proceed, then the car stalls when she attempts to go. The symptom set she described to me sounded as if there was a problem delivering fuel, but since the Check light flashes on, I elected to check for stored codes before lining up my wrenches. The only stored code is P0340, which translates to a failing cam sensor. She also says that under load -- freeway driving -- on long inclines, the car does not hold its speed as well as it once did, and she feels a need to put her foot into it more than she remembers, and this prompts a downshift that she describes as very harsh. I don't know what this means because a single gear change from 5th to 4th shouldn't be a memorial event, but if the car was dropping from 5th to 3rd, that would be something to write home about. She does not mention that the Check light comes on during this kind of event. Obviously, if the cam forgets where it is then the engine is not going to run well, and this could explain all of the symptoms with a single cause. Where does the cam sensor physically live on the M52 motor? What is the price range for a new one? |

They are different, but both retail for right at $110 US each. You should be able to find them in the $50 to $70 range. |

Turns out, the intake cam sensor lives right next to the Oil Filter Canister, and is easy to replace, if the directions I downloaded are accurate. There is one screw holding the sensor on, but the screw is hidden so other stuff has to come off first -- basically a hose or two and another screw. The guy that did the write-up says an hour for the first time, quicker after that. Thanks. |
