EXHAUST GAS RECIRCULATION (EGR) SYSTEM 6E– 5
INSPECTION
Vacuum Switch Valve (VSV)
Check the resistance between the VSV connector terminals
using a circuit tester.
Cold Resistance: 37 - 44 (Ω) (for 12 volt)
Connect battery voltage between VSV connector terminals and
make sure of the continuity between the ports.
EGR Valve
With negative pressure applied to the diaphragm chamber,
make sure that the valve is smoothly actuated to make the
area between (1) and (2) ventilated.
Startup: About -18.66±2.67 Kpa (-140±20 mmHg)
Check to see if EGR valve is normally actuated under the
following conditions:
QWS off (After warming up)
Engine coolant temp: 80°C or higher
