19. Turn the ignition switch to LOCK (0).
20. Disconnect the EGR valve 5P connector.
21. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 3.
Is there 100 kOhms or more?
YES - Go to step 43.
NO - Go to step 22.
22. At the EGR valve side, measure the resistance between EGR valve 5P connector terminals No. 2 and No. 4.
Is there 100 kOhms or more?
YES - Go to step 43.
NO - Go to step 23.
23. Jump the SCS line with the HDS.
24. Disconnect PCM connector B (24P) (Skip this step if the connector is already disconnected.).
25. Check for continuity between PCM connector terminal B5 and body ground.
Is there continuity?
YES - Repair short in the wire between the PCM (B5) and the EGR valve, then go to step 44.
NO - Go to step 26.
26. Connect EGR valve 5P connector terminal No. 1 to body ground with a jumper wire.
27. Check for continuity between PCM connector terminal B5 and body ground.
Is there continuity?
YES - Go to step 28.
NO - Repair open in the wire between the PCM (B5) and the EGR valve, then go to step 44.
28. Remove the jumper wire from the EGR valve 5P connector.
29. Check for continuity between EGR valve 5P connector terminal No. 5 and body ground.
Is there continuity?
YES - Go to step 30.
NO - Repair open in the wire between the EGR valve and G101, then go to step 44.
30. Reconnect PCM connectors B (24P) and C (22P).
31. Connect the positive battery terminal to EGR valve 5P connector terminal No. 1 with a jumper wire.
32. Start the engine, and let it idle, then connect the negative battery terminal to EGR valve 5P connector terminal No. 5 with a jumper wire.
Does the engine stall or run rough?
YES - Go to step 51.
NO - Go to step 33.
33. Turn the ignition switch to LOCK (0).
34. Remove the EGR valve. Service and Repair
35. Clean any carbon build-up on the EGR valve with Acura genuine throttle plate cleaner.
36. Install the EGR valve. Service and Repair
37. Reconnect the EGR valve 5P connector.
38. Turn the ignition switch to ON (II).
39. Reset the PCM with the HDS.
40. Do the PCM idle learn procedure. PCM Idle Learn Procedure
41. Do the EGR TEST in the INSPECTION MENU with the HDS.
Is the result OK?
YES - Go to step 49.
NO - Go to step 42.
42. Turn the ignition switch to LOCK (0).
43. Replace the EGR valve. Service and Repair
44. Reconnect all connectors.
45. Turn the ignition switch to ON (II).
46. Reset the PCM with the HDS.
47. Do the PCM idle learn procedure. PCM Idle Learn Procedure
48. Do the EGR TEST in the INSPECTION MENU with the HDS.
49. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P2413 indicated?
YES - Check for poor connections or loose terminals at the EGR valve and the PCM, then go to step 1.
NO - Go to step 50.
50. Monitor the OBD STATUS for DTC P2413 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 49, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals at the EGR valve and the PCM, then go to step 1. If the screen indicates EXECUTING or OUT OF CONDITION, keep idling until a result comes on.
