EGR Valve Assembly Inspection

Reference: EGR VALVE ASSEMBLY REMOVAL AND INSTALLATION 

1. Check resistance between the following terminals of EGR valve (1) in each pair.

   If found faulty, replace EGR valve assembly.

   EGR valve resistance 

   Terminal "A" and terminal "B": 20-24 Ω at 20°C (68°F) 

   Terminal "C" and terminal "B": 20-24 Ω at 20°C (68°F) 

   Terminal "F" and terminal "E": 20-24 Ω at 20°C (68°F) 

   Terminal "D" and terminal "E": 20-24 Ω at 20°C (68°F) 

   Terminal "B" and valve body: infinity (∞) 

   Terminal "E" and valve body: infinity (∞)

2. Remove carbon from EGR valve gas passage.
   NOTE: Do not use any sharp-edged tool to remove carbon.
   Be careful not to damage or bend EGR valve, valve seat and rod.
3. Inspect valve (2), valve seat (3) and rod for fault, cracks bend or other damage.

   If found faulty, replace EGR valve (1) assembly.
