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