Measure voltage between body ground and ECM/PCM connector terminals A3 and A2 individually. ECM/PCM CONNECTOR A (31P) Wire side of female terminals Is there battery voltage? YES - Repair short to power in the wire between the ECM/PCM (A2, A3) and the PGM-FI main relay 1. NO - Replace the PGM-FI main relay 1.

DTC 38: VTEC System Malfunction Special Tools Required Oil pressure gauge Attachment 07NAJ-P070100 Low pressure gauge 07406-0070001 Hose oil pressure 07ZAJ-S5A0200 Reset the ECM/PCM (see page 11-168). Check the engine oil level, and refill if necessary. Start the engine. Hold the engine at 3.000 rpm (min-1) with no load (in Park or neutral) until the radiator fan comes on. Road test the vehicle: Accelerate in 2nd gear to an engine speed over 4,000 rpm. Hold that engine speed for at least 2 seconds. If DTC 38 is not repeated during the first road test, repeat this test 2 more times. Is the MIL on and does it indicated DTC 38? YES - Go to step 5. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the VTEC solenoid valve and at the ECM/PCM. Turn the ignition switch OFF. Remove the resonator (see page 11-148).
