DTC P2008: IMRC Solenoid Valve Circuit Open Turn the ignition switch ON (II). Clear the DTC with the HDS. Start the engine. Hold the engine speed at 2,000 rpm (min −1 ) without load (in neutral) until the radiator fan comes on, then let it idle. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2008 indicated?
YES | - | Go to Step 5 .
NO | - | Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the IMRC solenoid valve and the ECM.■
Check for Temporary DTCs or DTCs with the HDS. Are DTC P0045, P0403 and P2008 indicated at same time?
YES | - | Go to Step 6 .
NO | - | Go to Step 11 .
Turn the ignition switch OFF. Check No. 10 IGP2 (20 A) fuse in the under-hood fuse/relay box. Is the fuse OK?
YES | - | Go to Step 8 .
NO | - | Repair short in the wire between No. 10 IGP2 (20 A) fuse and PGM-FI main relay 2, then go to Step 22 . Repair short in the wire between PGM-FI main relay 2 and the EGR valve, the IMRC solenoid valve, the turbocharger boost control solenoid valve, then go to Step 22 .
Check PGM-FI main relay 2. Is PGM-FI main relay 2 OK?
YES | - | Go to Step 9 .
NO | - | Replace PGM-FI main relay 2, then go to Step 22 .
Disconnect PGM-FI main relay 2. Measure voltage between PGM-FI main relay 2 4P connector terminal No. 1 and body ground. Is there battery voltage?
YES | - | Repair open in the wire between PGM-FI main relay 2 and the EGR valve, the IMRC solenoid valve, the turbocharger boost control solenoid valve, then go to Step 22 .
NO | - | Repair open in the wire between No. 10 IGP2 (20 A) fuse in the under-hood fuse/relay box and PGM-FI main relay 2, then go to Step 22 .
Turn the ignition switch OFF. Disconnect the IMRC solenoid valve 2P connector. Turn the ignition switch ON (II). |
