I have a 2011 Chevy Express with a Collins School Bus body, 6.6 Duramax engine. I am getting two codes that will not clear. PO187 and PO673. Which I believe can be fixed by replacing the glow plug #3 and the Fuel Temp Sensor. I have been unable to locate the Fuel temp sensor and glow plug #3 hits the frame before it unthreads far enough to remove. I'm stumped.

Hi:

There are actually two fuel pressure temperature sensors. The one that is relevant for code P0187 is sensor 2 (or B).

I attached information below. The last pic is the best one I found showing the location of sensor 2.

As far as the injector, are you able to get enough clearance if you lift upward a bit on the engine with a floor jack?

Let me know. Also, let me know if this helps.

Take care,

Joe
