  1. Check for a loose or damaged EGR pipe. Is the EGR pipe OK? YES -Go to step 2. NO -Reconnect or replace the EGR pipe, then go to step 7 .
  2. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
  3. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F(70°C) Transmission in D Drive the vehicle at 25 mph (40 km/h) or less for 5 minutes Drive at a steady speed of 25 mph (41 km/h) or more (engine speed between 1, 500-3, 000 rpm) for 9 seconds or more.
  4. Monitor the OBD STATUS for DTC P0400 in the DTCs MENU with the HDS. Does the HDS indicate FAILED? YES -Go to step 5. NO -If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for an exhaust gas leak between the EGR pipe and the EGR valve. If the HDS indicates NOT COMPLETED, go to step 3 and recheck.
  5. Turn the ignition switch to LOCK (0).
  6. Replace the EGR valve (see «EGR VALVE REPLACEMENT»(ref-513186-S18122158842012110700000) ).

  10. Test-drive under these conditions: Engine coolant temperature (ECT SENSOR 1) above 158°F(70°C) Transmission in D Drive the vehicle at 25 mph (40 km/h) or less for 5 minutes Drive at a steady speed of 25 mph (41 km/h) or more (engine speed between 1, 500-3, 000 rpm) for 9 seconds or more.
  11. Check for Pending or Confirmed DTCs with the HDS. Is DTC P0400 indicated? YES -Check for a leak between the EGR pipe and the EGR valve, then go to step 1 . NO -Go to step 12.
  12. Monitor the OBD STATUS for DTC P0400 in the DTCs MENU with the HDS. Does the HDS indicate PASSED? YES -Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 11 , go to the indicated «DTC'S TROUBLESHOOTING»(ref-513186-S33865309972012110700000) .
