First time dealing with CPT sensor. Which one, and where is it.
 

Hi all.

I got an SES today while driving around the city all morning. This is the second time in 2 years that this came up. I have not scanned with INPA yet. Just used my quick and dirty OBD2 cheapo scanner that I keep in the glove box.

So I have this.
P0021 - Intake (A) Camshaft Position timing - over - advanced (Bank 2)
P0355 - Camshaft Position sensor A circuit (bank 2)

I forget which is bank 1 and 2 on these cars.

Also, where the hell is this thing located. I have never had to deal with one on any of my previous BMWs.

Here is a realoem link.
RealOEM.com * BMW E53 X5 4.8is Sensors

Thanks in advance guys. Hope to place the order tomorrow.

No one had this issue?

кому не спится в ночь глухую???

sorry man, i have no idea about this problem... just stopped by to say Hi... :)

2 kids. This the only time to post. I see you're up as well. I might have to text TTGTR. I think he we t through something similar on his 4.4.

Oh and Hi.

Bank one is normally where number 1 thru 4 spark plugs are located and bank two is where number 5 thru 8 spark plugs are located.

Ok so bank 1 is the pass side. Bank 2 is the Drivers. Thank you TTGTR.

Now, realoem shows 3 of these on the engine. Does anyone know which is the intake side.

Ok so figured it out and fixed the problem.

Intake side is bank 2, which is driver side. Sensor is at top read of valve cover, plugs into the intake manifold area. The plug was lose. As soon as I pulled on it, it fell off. Put it back on with solid click. Hope no more issues. Love free fixes.

I just experienced that code related to cam sensor, ses light came on, there is 4 sensors on mine (4.4 n62) 2 were shot with oil leaks in and out....my INDY bought it from OEM BMW (do not go fot cheap ebay) ...$199cdn each :wow:...i've changed 2 ...idle is great (not perfect) and SES off...

Mine is N62 as well. Except 4.8. Yea we have 4, but one is the intake side, and it has the wire attached to it. Thats the one on the bank2, drivers side. Mine was plugged in, but not fully. Thats why i guess i got that random code.

Good catch!

Pure luck. Found the sensor and was tracing the wire back. Once I got close to the connector, it just fell off. I said WTF, and plugged it back in, this time it's on good.

I know the feeling of complete relief coupled with the can't be this simple anxiety that soon overrides until there is proof all is well. What should be lasting is not that you were lucky but pride that you were wise to do the troubleshooting rather than buying new parts.
