DTC P0195: Engine Oil Temperature Sensor Circuit

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
DTC P0195: ENGINE OIL TEMPERATURE SENSOR CIRCUIT

Description:  This DTC sets when the engine oil temperature (EOT) sensor is not within the PCM predicted engine oil temperature range, based on other PCM inputs.
Possible Causes: 
  • SIGRTN circuit open
  • SIGRTN circuit short to voltage
  • EOT circuit open
  • EOT circuit short to ground
  • EOT circuit short to voltage
  • Engine not operating long enough prior to carrying out the key ON, engine running (KOER) self-test
  • Cooling system concern
  • Stuck thermostat
  • Damaged EOT sensor
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.
