Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
2. COMPONENT DESCRIPTION
The variable valve lift system optimizes the intake valve lift by switching between the low lift cam and the high
lift cam according to the engine RPM. The amount of intake valve lift is varied by controlling the oil switching
solenoid valve duty according to signals from the ECM.
3. ENABLE CONDITIONS
(A) When at low speed (B) When at high speed
(1) Oil switching solenoid valve
Secondary Parameters Enable Conditions

GENERAL DESCRIPTION
BH:DTC P0196 ENGINE OIL TEMPERATURE SENSOR CIRCUIT RANGE/PER-
FORMANCE
1. OUTLINE OF DIAGNOSIS
Detect for abnormal values in the oil temperature sensor output properties.
Judge as NG when the oil temperature does not rise even though the engine is running under a condition
where it should rise.
2. ENABLE CONDITIONS
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously after starting the engine.
4. DIAGNOSTIC METHOD
Abnormality Judgment
When the following conditions are established, it is NG.
After engine start oil temperature sensor characteristic diagnosis timer (timer for diagnosis).
a. Timer stop at fuel cut.
b. During the driving conditions except a) above, timer count up by
64 milliseconds + TCILCNT milliseconds at every 64 milliseconds.
Where, TOILCNT is determined as follows,
TOILCNT = 0 at idle switch ON
For TOILCNT at Idle switch off, refer to the following table.
After engine start oil temperature characteristic diagnosis timer judgment value (t).
t = 2400000 – 60000 × Ti (t ≥ 2400000)
Ti = The lowest coolant temperature after starting the engine.
Time Needed for Diagnosis: Undecided
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
