EGR Valve Inspection

• Check EGR valve for wear or damage.
CAUTION
!
Do not disassembly EGR valve.
1) Check resistance between following terminals of

specification, replace EGR valve.
EGR valve resistance
Terminal
Between 1 and 5 terminals 2.96 ± 0.3 Ω at 20 °C, 68 °F
Between 2 and 4 terminals 6.5 ± 0.6 kΩ at 20 °C, 68 °F
2) Check EGR valve operation as following procedure.
If check result is not satisfied, replace EGR valve.
a) When connecting battery positive (+) terminal to
