1987 Ford LTD Crown Victoria 5.0L Vacuum Diagram - Calibrations 7-22/7-23

This document is a scanned vacuum routing diagram (Fig. 4) from Mitchell Repair Information Company (© 2003), credited as courtesy of Ford Motor Co., for the 1987 Ford LTD Crown Victoria with the 5.0L engine. It applies to a specific set of engine calibrations: 7-22B-R00, 7-22E-R00, 7-22E-R10, 7-22G-R00, 7-22H-R00, 7-22H-R10, 7-22I-R00, 7-22J-R00, 7-22Q-R00, 7-22S-R00, 7-23B-R00, 7-23C-R00, and 7-23R-R00. The schematic shows vacuum hose routing among emissions and engine-control components, identified by abbreviations: MAP sensor, PCV valve, vacuum reservoir (VRESER), fuel pressure regulator (FPR), vacuum check valve (VCKV), EVR, air control valve (ACV), two solenoid valves (SOL V), air bypass valve (ABV), four manifold vacuum (MAN VAC) taps, EGR valve, air pump, CPRV, vacuum restrictor (V-REST), fuel tank line, and charcoal canister (CAN). Solid lines indicate vacuum hoses and dashed lines indicate reference/other connections, with orientation noted as "FRONT OF VEHICLE." A reader can use this diagram to verify or restore correct vacuum hose routing on a matching 5.0L calibration, useful when diagnosing emissions, EGR, air injection, or evaporative system problems. Figure ID number 200742 appears on the diagram; the page was printed February 13, 2004.
