Ford 4.2L CHT Sensor Location Diagram - Service Illustration AV1682-A

This document is a single black-and-white line-art service illustration bearing the Ford illustration reference number AV1682-A. It depicts a section of an engine with surrounding wiring harnesses and hoses, and a large bold arrow calls out the location of a specific sensor/electrical connector on the engine. The image contains no legend, part numbers (other than the illustration code), torque values, or descriptive text, so its meaning depends on the service procedure it accompanies. Based on the uploader's filename ('4.2 cht.gif'), the illustration is filed as showing the cylinder head temperature (CHT) sensor location on a 4.2L engine, though the document itself does not state this. A reader can learn the physical location of the indicated component relative to nearby engine features and harness routing, which is useful for locating and disconnecting the sensor during diagnosis or replacement. The album it belongs to contains many Ford truck (F-150 era) wiring diagrams and engine illustrations, suggesting this page is one figure from a larger factory service manual set rather than a standalone document.
