Is there continuity?
YES -
Go to step 23.
NO -
Repair an open in the wire between the ECM/PCM(B30) and the EGR valve, then go to step 44.
21. If not already done, turn the ignition switch to LOCK (0).
22. If not already done, disconnect the EGR valve 5P connector.
23. 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 24.
24. 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 27.
25. If not already done, jump the SCS line with the HDS.
26. If not already done, disconnect ECM/PCM connector B (49P).
27. Check for continuity between ECM/PCM connector terminal B2 and body ground.
Is there continuity?
YES -
Repair a short in the wire between the ECM/PCM(B2) and the EGR valve, then go to step 44.
NO -
Go to step 28.
28. Check for continuity between ECM/PCM connector terminal B2 and EGR valve 5P connector terminal No. 1.
Is there continuity?
YES -
Go to step 29.
NO -
Repair an open in the wire between the ECM/PCM(B2) and the EGR valve, then go to step 44.
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 an open in the wire between the EGR valve and G101, then go to step 44.
30. Reconnect ECM/PCM connector B (49P).
31. At the EGR valve side, connect the battery positive terminal to EGR valve 5P connector terminal No. 1 with a jumper wire.
32. Start the engine, and let it idle. Then connect the battery negative terminal to EGR valve 5P connector terminal No. 5 with a jumper wire.
Does the engine stall?
YES -
Go to step 50.
NO -
Go to step 33.
33. Turn the ignition switch to LOCK (0).
34. Remove the EGR valve Service and Repair.
35. Clean the intake manifold EGR port Service and Repair and the EGR pipe with throttle plate cleaner Service and Repair. Also, clean the passage inside the EGR valve with throttle plate cleaner.
36. Install the EGR valve Service and Repair.
37. Reconnect all connectors.
38. Turn the ignition switch to ON (II).
39. Reset the ECM/PCM with the HDS.
40. Do the ECM/PCM idle learn procedure ECM/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.

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 ECM/PCM, then go to step 1.
NO -
Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
50. Turn the ignition switch to LOCK (0).
51. Reconnect all connectors.
52. Update the ECM/PCM if it does not have the latest software ECM/PCM Update, or substitute a known-good ECM/PCM.
53. Do the EGR TEST in the INSPECTION MENU with the HDS.
54. 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 ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then go to step 53. If the ECM/PCM was substituted, go to step 1.
NO -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
