2002 Pathfinder 3.5 V6 P1401 SES code EGR Temp Sensor

[bablazer]

SES code indicates EGR Temp Sensor fault P1401

Just replaced IAC Valve after P0507 code and followed re-learning procedure and engine will not idle when hot, no power, throttle response is sluggish.

Problem: cannot locate EGR valve and EGR temp sensor at all. Removed upper and lower plenum and replaced PCV valve and no EGR valve to be found.

Anyone out there follow my dilemma? I've been working on cars for almost 40 years, not a rookie.

Haynes manual shows NOTHING for 2002 with 3.5 V6?

Help!
