According to my source, P0196 is an engine oil temperature sensor circuit failure of some kind. My source is sketchy so not sure of more details.

P0196 Engine Oil Temperature Sensor Circuit Range/Performance

Description...

Indicates the value from the engine oil temperature (EOT) sensor is not within the powertrain control module (PCM) predicted engine oil temperature range, based on other PCM inputs.

Possible Causes...

Engine not at operating temperature
EOT circuit concern
EOT sensor
Cooling system problem or stuck thermostat

Diagnostic Aids...

The EOT rationality test looks for the EOT sensor value to be within a calibrated parameter of the PCM predicted engine oil temperature. Make sure the EOT sensor reading is similar to engine temperature. If the EOT reading greatly differs from engine temperature, check the EOT circuitry for correct operation.

The latest update from the ford dealer is supposed to be a fix for this, I had this code today at work as a matter of fact. Reprogrammed the ecu and now customer said the light stayed off.
