WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
- Do not disconnect the cable from the negative (-) battery terminal when the power supply of the continuously variable valve lift controller assembly is energized.
-
Because the VALVEMATIC system memorizes settings when the ignition switch is turned off, make sure to wait at least 1 minute after turning the ignition switch off before disconnecting the cable from the negative (-) battery terminal.
If the cable is disconnected from the negative (-) battery terminal when the power supply is energized or within 1 minute after turning the ignition switch off, DTC P265B may be stored.
- Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

(b) Start the engine and warm it up until the engine coolant temperature stabilizes. (Engine coolant temperature 40°C or higher)
(c) Turn the ignition switch off.
(d) Restart the engine.
HINT:

(g) Check the Data List "VALVEMATIC bef Warm Up" display is "ON".
HINT:
If "VALVEMATIC bef Warm Up" is not "ON".
- Restart the engine. (Do not operate the accelerator pedal.)
- Perform the Active Test "Activate the VALVEMATIC before Warm Up" to set "VALVEMATIC bef Warm Up" to "ON". (Do not operate the accelerator pedal.)
(h) Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "High" and check that "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.
Standard:
|
Techstream Operation |
Result |
|---|---|
|
High |
VALVEMATIC Current Angle: 260 deg(CA) MAP: 25 to 40 kPa (3.6 to 5.8 psi) |
(i) Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "OFF", and check that "VALVEMATIC bef Warm Up" returns to "ON".
(j) Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "Low" and check that "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.
Standard:
|
Techstream Operation |
Result |
|---|---|
|
Low |
VALVEMATIC Current Angle: 106 deg(CA) MAP: 35 to 65 kPa (5.1 to 9.4 psi) |
OK:
When performing the Active Test, "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.
HINT:
- After the accelerator pedal is depressed and the Active Test operates once to "Low", "VALVEMATIC bef Warm Up" does not return to "ON". Therefore, in order to repeat the inspection, it is necessary to either perform the Active Test "Activate the VALVEMATIC before Warm Up" to set the VALVEMATIC system to the operating position that occurs before the engine is warmed up, or restart the engine.
- When the vehicle is driven while there is a malfunction in the VALVEMATIC system and the valve lift amount is fixed at the minimum, the vehicle speed cannot exceed 30 to 60 km/h (19 to 37 mph).
- If the intake valve advance angle is within the VALVEMATIC operation prohibition range depending on the operating state of the VVT system, the Active Test "Activate the VALVEMATIC(ENG ON)" is prohibited. If the advance angle cannot be detected due to a malfunction in the VVT system, the Active Test "Activate the VALVEMATIC(ENG ON)" is prohibited.
