The ground terminal(terminal No. 5) is grounded with ECM (terminalNo. 40).• A voltage that is proportional to the atmosphericpressure is sent to the ECM (terminal No. 85)from the barometric pressure sensor output terminal(terminal No. 2)..TECHNICAL DESCRIPTION• The barometric pressure sensor outputs a voltagewhich corresponds to the barometric pressure.• The ECM checks whether this voltage is within aspecified range..TSB Revision
