17. 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

1. Reset the ECM/PCM (see page 11-168).
2. Check the engine oil level, and refill if necessary.
3. 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.
4. 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.

5. Turn the ignition switch OFF.
6. Remove the resonator (see page 11-148).
