I have a 99 Tropi-cal with a first generation Triton V-10
Every so often I get the service engine light trip with a a code 1406 which apparently refers to the Differential Pressure Feedback Electronic Sensor Circuit Downstream Hose. It seems to come on mostly when I have the rig under hard acceleration such as when merging on to an interstate with a short ramp. The problem is that I can't seem to find the thing on the engine. It is supposed to look something like this. Anybody know where it is, maybe have a picture of it's location? Thanks in advance for any help.
