P0196 EOT SENSOR
(Engine oil temperature sensor
range/performance) A)
Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from EOT sensor
and intake air temperature sensor. • Harness or connectors
(EOT sensor circuit is open or short-
ed)
• EOT sensor
B) The comparison result of signals trans-
mitted to ECM from each temperature
sensor (IAT sensor, ECT sensor, FTT
sensor, and EOT sensor) shows that the
signal voltage of the EOT sensor is high-
er/lower than that of other temperature
sensors when the engine is started with
its cold state. • Harness or connectors
