6E-208 EMISSION AND ELECTRICAL DIAGNOSIS
Working Check
Apply powervoltage between the terminals, there
is no problem if the negative pressure does not rise
when applied to the input port.
Caution:
When measuring resistance with a circuit tester, be
careful not to damage or deform the terminals.
3. Exhaust Gas Recirculation (EGR) Valve
With negative pressure applied to the diaphragm
chamber, make sure that the valve is smoothly ac-
tuated to make the area between (1) and (2) venti-
lated.
Startup: About -13.3
± 2.7 kPa (-100 ± 20 mmHg /
-1.93
± 0.39 psi)
Check to see if EGR valve is normally actuated un-
der the following conditions:
Engine coolant temp.: 80
°C (176°F) or higher
