(Trouble diagnosis content) DTC detecting condition Possible cause
P0196 EOT SENSOR
[Engine oil temperature (EOT)
sensor circuit range/perfor-
mance] 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
(The EOT sensor circuit is open or
shorted)
• 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
(High or low resistance in the EOT
sensor circuit)
• EOT sensor
