Re: My check engine light is on.

P1406 - EGR system... Check downstream hose hose off or blocked.

Re: My check engine light is on.

I don’t want to sound like a newb but were is it? is it the metal pipe from the manifold to the egr? If so what do I do to fix it?

thanks

Re: My check engine light is on.

2 electric blue tubes on driver's side of engine connect to a sensor. They could be disconnected from the sensor or underneath the car.

+1.

If memory serves me right (which it's been sketchy lately...LOL), the connection is near the EGR - between it and the firewall.

Re: My check engine light is on.

Ok guys, thanks I’ll see if I can get this stupid light off. BTW can I reach both locations by hand with the car on the ground? And I don’t think it would but will it hurt to drive it until I can fix it?

Thanks again.
