input sensor

[halbec78]

Could You Please Tell Me The Location Of The Input Sensor On My 2000 Dodge Durango, V-8(318),auto? My Ouput Sensor Went Out And I Was Told, (by A Reputable Mechanic) To Change The Input Sensor At The Same Time. I Have Already Purchased Both Sensors From The Dealer, But They Will Not Tell Me Where They Go. I Found The Output Sensor And Changed It And Got Rid Of My Trouble Codes, But They Want $75.00 Plus The Cost Of The Sensor To Do The Job. It Should Not Be Hard To Change If I Know Where To Look, My Chilton Book Does Mention It At All.

Thanks For Your Help,

Hal Morgan
