EGR Valve Assembly Inspection

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 ohm at 20 °C (68 °F)

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

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

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

Terminal "B" and valve body: infinity

Terminal "E" and valve body: infinity

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.
Inspect valve (2), valve seat (3) and rod for fault, cracks, bend or other damage. If found faulty, replace EGR valve (1) assembly.
