P0196 Engine Oil Temperature Sensor-Range / Performance

General Information

Component Location





General Description

The Continuously Variable Valve Timing (CVVT) system uses engine oil pressure to change the camshaft timing according to engine operating conditions. Engine oil viscosity changes according to engine temperature. The Oil Temperature Sensor (OTS) signal along with coolant and intake air temperature is used by the PCM to compensate for changes in oil viscosity when commanding the Oil Control Valve (OCV). The OTS measures the engine oil temperature before the engine oil flows through the OCV.

DTC Description

The PCM monitors oil temperature, coolant temperature and intake air temperature every 25 seconds. If the difference in temperature at start-up exceeds threshold value, the PCM sets a P0196 DTC.
