P0196 Engine Oil Temperature Sensor-Range / Performance
General Information
Component Location

General Description
The fluid of the CVVT is the engine oil and its density changes according to the engine oil temperature. At this time the Oil Temperature Sensor (OTS) helps compensation against the temperature differences. The Oil Temperature Sensor measures the engine oil temperature before the engine oil comes into the Oil-flow Control Valve (OCV).
According to the measured temperature, the Engine Control Module (PCM) compensates the oil-flow control valve operation time.
DTC Description
Checking the oil temperature, coolant temperature and intake air temperature every 25 sec. under detecting condition, if the difference in temperature at start-up exceeds threshold value, PCM sets P0196.
