The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.

MALFUNCTION THRESHOLD

ENABLE CONDITIONS

When the rocker arm oil control solenoid (VTEC solenoid valve) is ON, the rocker arm oil pressure switch (VTEC oil pressure switch) remains ON.

Do the VTEC TEST in the INSPECTION MENU with the HDS.

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. Drive the vehicle in a lower gear at 4,000 rpm or more with a MAP value of 27 kPa (7.9 in.Hg, 200 mmHg) or more for at least 10 seconds.

1. Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the ECM/PCM memory.

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.

ENABLE CONDITIONS

Low lift cam operation

When the rocker arm oil control solenoid (VTEC solenoid valve) is OFF, the rocker arm oil pressure switch (VTEC oil pressure switch) remains OFF.

Do the VTEC TEST in the INSPECTION MENU with the HDS.

Start the engine, and let it idle for at least 10 seconds.

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the ECM/PCM memory.

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.

Rocker Arm Oil Control Solenoid Circuit Diagram. Scheme 369

ENABLE CONDITIONS

The return signal is OFF (Low) for at least 1.1 seconds when the ECM/PCM outputs the ON (High) signal to the rocker arm oil control solenoid (VTEC solenoid valve).

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. Drive the vehicle in a lower gear at 4,000 rpm or more with a manifold absolute pressure (MAP) value of 27 kPa (7.9 in.Hg, 200 mmHg) or more for at least 10 seconds.

1. Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

A/F Sensor Voltage Graph. Scheme 370

ENABLE CONDITIONS

The A/F sensor output voltage is 2.8 V or less, or 4.8 V or more.

Vehicle Speed Driving Pattern. Scheme 371

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. Drive the vehicle at a speed between 25 - 55 mph (40 - 88 km/h) for at least 5 minutes.
3. Then, drive immediately at a steady speed between 55 - 75 mph (88 - 120 km/h) for at least 10 seconds.
4. Decelerate with the throttle valve fully closed for at least 4 seconds.

1. If the EVAP monitor runs instead of the HO2S monitor, turn the engine off, then restart it, and the HO2S monitor will restart.
2. Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the freeze frame data are stored.

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
