P0196: Engine Oil Temperature (EOT) Sensor Circuit Range/Performance
WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P0196 - ENGINE OIL TEMPERATURE (EOT) SENSOR CIRCUIT RANGE/PERFORMANCE
| Description: | Indicates the sensed EOT value from the EOT sensor is not within the PCM predicted engine oil temperature range, based on other PCM inputs. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | The EOT rationality test looks for the engine oil temperature sensor to be within a calibrated delta of the PCM predicted engine oil temperature. Make sure EOT sensor reading is similar to the engine temperature. If the EOT reading greatly differs from engine temperature, check the EOT circuitry for correct operation. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
