Measure the resistance at the following terminals:
- EGR valve terminal A-EGR valve terminal C.
- EGR valve terminal E-EGR valve terminal C.
- EGR valve terminal B-EGR valve terminal D.
- EGR valve terminal F-EGR valve terminal D.
  EGR valve resistance (specification)
  
  8.0-9.0 ohms [20 °C {68 °F}]
- If not within the specification, replace the EGR valve. (See EGR VALVE REMOVAL/INSTALLATION .)
