94 DPFE hose routing

[awood]

Can anyone give me a quick description where the two EGR DPFE sensor hoses are routed? My 94 is fairly new to me, and I don't have another to compare with. Their current position doesn't look natural.

Just trying to figure out a CEL after getting above 40 to 45 mph, with lean banks 1 and 2 codes. Seems to run ok though.

The DPFE Hoses run down below the sensor to two metal tubes off the exhaust.
I think if I remember right one is above the other and just a little behind the sensor and the other is practically straight down.

Take a picture of your's and we'll be able to tell you if it's right or not.

Found a drawing on Google images. The hose that attaches above the orifice restricter in the riser tube goes to the port labeled "Ref" on the sensor.

The other hose goes to the other port.

Thanks.
