Here we go again, so I have a 02 Max GLE auto tranny 127,000 miles everything stock. A while now I been experiencing a loss of power, its been getting progressively worse over time. When accelerating slightly there's sort of a rattling sound that also gotten louder. You only hear it under slight acceleration, under load the sound is gone. I also hear the same rattling noise at start up.(Mainly cold starts) I had no check engine light so wasn't sure where to start. Yesterday my check engine light came on codes P0455, P0011, P1448, P1615. I'm not sure if these codes have anything to do with the loss of power I've been experiencing. The last code P1615 is for the anti theft system, I'm sure its unrelated to the others. I'm sure its one malfunctioning part causing the other codes to go off. Can anyone point me in the right direction so I won't have to change a bunch of parts before I get it right. Thanks in advance

also that rattling is your timing chain tensioner on its way out, I would advise to let the car warm up a bit before driving until you can fix it

as said above, the P0011 code might be your problem, if you're going to replace that sensor, OEM only please

 

Can you tighten the timing chain tensioner?

Also I have a extra crankshaft sensor I bought I'll change it maybe later or 2morro to see if it makes a difference

 

Ok so I just install a brand new crankshaft position sensor (OEM) this morning, car still feels the same. Anymore advice?

 

Help! Still having same issues

 

Did you check your connections for all the sensors?

 

alternator all good?

 

Yeah I did everything is all connected

 

I'm 100% sure it's not alternator, been working on cars long enough. Car as brand new alternator btw

 

Legit brand?
