Grand Vitara 4WD L4-2.4L (2009)
EVAP leak check pressure sensor output voltage for initial (barometric) pressure (Terminal "4" voltage 4.5 - 5.5 V at ambient temperature of
20 - 30 °C (68 - 86 °F))
2. Reference vacuum pressure (reference orifice vacuum) check:
a. In the state of Step 1), operate EVAP leak detection pump by connecting 12 V-battery to terminal "1" and terminal "5" of EVAP leak check
module. Check that pressure sensor output voltage (reference orifice vacuum) becomes lower than pressure sensor output voltage of Step 1) by
approx. 0.1 V.
If sensor voltage is out of specification, replace EVAP leak check module.
