INSPECTION
1. EGR VALVE ASSY
(a) Check for sticking and heavy carbon deposits.
If a problem is found, replace the EGR valve.
2. VACUUM CONTROL VALVE
(a) Connect the MITYVAC (Hand–Held Vacuum Pump) to
port S of the VCV.
(b) Plug port Z completely with fingers.
(c) Perform pumping 3 times and apply vacuum as shown in
the illustration.
(d) Stop the performing pumping and check the indicated val-
ue of the MITYVAC after about 10 seconds.
Standard value:
15 – 24 kPa (112 – 180 mmHg, 4.4 – 7.1 in.Hg)
If the indicated value is not as specified, replace the VCV.
3. E.G.R GAS TEMPERATURE SENSOR
(a) Resistance inspection
(1) using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance:
At 50C (122F) 69.4 – 88.5 Ω
At 100C (212F) 11.89 – 14.37 Ω
At 150C (302F) 2.79 – 3.59 Ω
