Cam sensor
 

I went to Azone and used the OBD tool. I pulled a sensor code. Went to BMW/Fairfax to get the new sensor. Replaced it and the SES light went out. Great.. But last night i get in and guess what. The damn light is on. Do i need to clear the code now? Also, my airbag light is on from when i unplugged it. Can i clear that somehow at AZone?

Did you replace the correct sensor?
AB light - Buy a Peake AB reset tool.

Post the code and the sensor and someone might be able to help you.

P0348.
Camshaft positioning sensor. Bank 2. I was told that is was on the passenger side of the engine. And BMW said both sides are the same part and number.. I dont have the paperwork in front of me.

I'm not familiar with P0348. It's listed as UNKNOWN and I don't have my Bentley manual handy. When I replaced the intake cam sensor on my 330 I reset the code. I would see if the SES is caused by the same code. If it is then you need to reset it.

PO348 Cam Position Sensor A Bank 2, High input. Wiring short to positive, faulty sensor or ECM.

And i changed the Sensor, now the light is back on. Sansor A bank 2, is that the right side of the block? If i did change the right sensor, do i need to just clear the code?

You do need to clear it. I had to clear it last year when a sensor was replaced.

Thanks for all your help..

^^^ yup need to clear code like Zulu95 said, because it's still in memory, once cleared your light will go away for good ;p

I think i love you people...lol

Well i went back to clear. And minutes into the drive it came back on?????
I am i correct bank 2 snsor a is on the passenger side of the X5??
Any ideas???

Has this been addressed by the dealer at all? I did not see any service
done in your post. Just wondering if have a true engine problem?

Not addressed by a dealer. And i am worried that it is a true engine issue.

Did you try changing the other sensor?

I didnt try to change the other. I would hate to spend another $125.00 for no reason. I may try to move the new sensor to the other side. just switch them up. Is that smart at all?

You could switch them. Good for trouble shooting. If the problem follows to the other side (bank one) you'll have your answer.

If you still have the old sensor you may want to put it back in the original side and put the new sensor in the other side (bank one). That way you'll only need to change them once if that's the problem.

Any updates on if switching the side worked? I'm having the identical problem.

I hate to revive such an old thread but I guess it's better than creating a new one! I've just run across this same problem. I replaced both sensors for good measure since they were never replaced and for a little while all was fine. Then one day, on startup, it threw the above mentioned code. I reset it and it stays off for the duration of the drive, but as soon as I restart the truck the code reappears.

Anyone have any luck diagnosing this? TIA!

Exactly the same problem recently. I changed the 2 sensors as a preventative maintenance. The intake one failed immediately, throwing the code and causing some issues while starting the engine. Replaced by the old one and all went well. The exhaust one failed about 3 weeks later, once again I put the old one...
My fault, I ordered some aftermarket ones (Ekon brand) instead of the OEM...

Not necessarily so. I hooked up my Actron CP9135 and cleared the code. Drove about 25 miles and the SES light is back on. Hooked up my Actron and again, code P0348 - Camshaft Position Sensor A - Bank 2 circuit High Input.

I was told it is on the passenger side near the front/top of the engine. Did I replace the correct one? If so, now what?

I know it's been 8 years, but does anyone know if bank 2 is on the pass. side? Same issue here and want to replace the correct one '02 4.4i

On the M62, bank 1 is the right side of the engine (passenger) and bank 2 is the left side of the engine (driver).
