Last couple days the engine on my 07 GL450 randomly stalled. When It was driven it started back in a split second but when idling, did not.
Check engine light came on and ESP, then both went away. Still there’s a few codes stored as it follows
P2004
P2610
P0335
I live in Vegas and it’s been 115 last couple days. I suspect is the heat combined with a loose connection, maybe a faulty sensor closing the intake manifold.
What are your recommendations on where to start first?
Thanks

 

Crankshaft position sensor is the most likely culprit here.

the 0521 is for a broken intake manifold tumble flap actuator - they all break - and can be left alone.

 

Is there a way to test it? Or just have it replaced?
thanks

 

I’ve never found testing a CPS to be worth the cost of a new part and labor - it’s a fairly easy fix.

 

I dropped it at the shop in the morning. The mechanic said the intake manifold assembly needs to be replaced and the crankshaft sensor as you said. Parts and labor with taxes is $1630. I asked them to replace my spark plugs while is taken apart and they’ll charge me another $160 on top.
I need the car running by Thursday and they had the parts in the shop, so I agreed with them...
Thanks for your help man.
