Fig. 91 MAP sensor installation. 1984 V6-231
The MAP and Vacuum sensors are accessible through the engine compartment. The BARO sensor may be located either in the engine compartment or
strapped to the ECM harness under the dash panel. Other than checking for loose hoses and electrical connections, the only service required of these
sensors is replacement, should diagnosis show any sensors to be faulty.
