P0206
DTC P0206: No.6 Injector Circuit Malfunction1. Clear the DTC with the HDS.
2. Start the engine with no load (in Park or neutral), then let it idle.
3. Check for Temporary DTCs or DTCs with the HDS.
Is P0201, P0202, P0203, P0204, P0205, and/or P0206 indicated?
YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the appropriate injector and at the PCM.
4. Turn the ignition switch OFF.
5. Jump the SCS line with the HDS.
6. Disconnect PCM connector A (73P).
7. Turn the ignition switch ON (II).
8. Measure voltage between body ground and the appropriate PCM connector terminal.
Is there battery voltage?
YES - Go to step 19.
NO - Go to step 9.
9. Turn the ignition switch OFF.
10. Remove the intake manifold.
11. Disconnect the injector 2P connector from the problem cylinder.
12. Turn the ignition switch ON (II).
13. Measure voltage between injector 2P connector terminal No.1 and body ground.
Is there battery voltage?
YES - Go to step 14.
NO - Repair open in the wire between the injector and PGM-FI main relay 1, then go to step 24.
14. Turn the ignition switch OFF.
15. Check for continuity between body ground and the appropriate PCM connector terminal.
Is there continuity?
YES - Repair short in the wire between the PCM and the injector, then go to step 24.
NO - Go to step 16
16. Connect the appropriate injector 2P connector terminal No.2 to body ground with a jumper wire (see table).
17. Check for continuity between body ground and the appropriate PCM connector terminal.
Is there continuity?
YES - Go to step 18.
NO - Repair open in the wire between the PCM and the injector, then go to step 24.
18. Measure resistance between the injector 2P connector terminals No.1 and No.2
Is there 10 - 13 Ohms?
YES - Go to step 19.
NO - Replace the injector, then go to step 24.
19. Substitute a known-good injector to the problem cylinder.
20. Reconnect PCM connector A (73P).
21. Start the engine, and let it idle for 2 minutes.
22. Test-drive the vehicle for several minutes in the range of the recorded freeze data.
23. Check the CYL1, CYL2, CYL3, CYL4, CYL5, and/or CYL6 MISFIRE in the DATA LIST for 10 minutes with the HDS.
Does CYL1, CYL2, CYL3, CYL4, CYL5, and/or CYL6 MISFIRE count the misfire?
YES - Go to step 30.
NO - Replace the original injector, then go to step 24.
24. Reconnect PCM connector A (73P) and the injector 2P connector.
25. Turn the ignition switch ON (II).
26. Reset the PCM with the HDS.
27. Do the PCM idle learn procedure.
28. Test-drive the vehicle for several minutes in the range of the recorded freeze data
29. Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P0201, P0202, P0203, P0204, P0205, or P0206 is indicated, check for poor connections or loose terminals at the injector and the PCM, then go to troubleshooting DTC P0201, P0202, P0203, P0204, P0205, or P0206 If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting
NO - Troubleshooting is complete
30. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
31. Test-drive the vehicle for several minutes in the range of the recorded freeze data
32. Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
YES - If DTC P0201, P0202, P0203, P0204, P0205 or P0206 is indicated, check for poor connections or loose terminals at the injector, the ignition coil, and the PCM, then go to step 1. If any other Temporary DTCs or DTCs indicated, go to indicated DTC's troubleshooting
NO - If the PCM was updated, troubleshooting is complete If the PCM was substituted, replace the original PCM.
