H : DTC P0196, P0197, P0198. OIL TEMPERATURE SENSOR

H1 : CHECK THE OIL TEMPERATURE SENSOR SIGNAL WIRE FOR OPEN CIRCUIT

1. Turn the ignition switch to the OFF position.
2. Disconnect the oil temperature sensor electrical connector EN25.
3. Disconnect the PCM electrical connector EN16.
4. Measure the resistance between the oil temperature sensor electrical connector EN25, pin 1 (Y) and the PCM electrical connector EN16, pin 78 (Y).

Is the resistance less than 5 ohms?
Yes
Goto H2

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

H2 : CHECK THE OIL TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT

1. Measure the resistance between the oil temperature sensor electrical connector EN25, pin 2 (BG) and GROUND.

Is the resistance less than 5 ohms?
Yes
Goto H3

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

H3 : CHECK THE OIL TEMPERATURE SENSOR GROUND CIRCUIT FOR SHORT TO BATTERY

1. Connect PCM electrical connector, EN16.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the oil temperature sensor electrical connector EN25, pin 2 (BG) and GROUND.

Is the voltage greater than 1 volt?
Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto H4

H4 : CHECK THE OIL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO GROUND

1. Turn the ignition switch to the OFF position.
2. Disconnect PCM electrical connector, EN16.
3. Measure the resistance between the oil temperature sensor electrical connector EN25, pin 1 (Y) and GROUND.

Is the resistance less than 10,000 ohms?
Yes
REPAIR the short to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto H5

H5 : CHECK THE OIL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO BATTERY

1. Connect PCM electrical connector, EN16.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the oil temperature sensor electrical connector EN25, pin 1 (Y) and GROUND.

Is the voltage greater than 10 volts?
Yes
REPAIR the short to battery. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
INSTALL a new oil temperature sensor. CLEAR the DTCs. TEST the system for normal operation. If the DTC is repeated, INSTALL a new PCM. Before replacing a PCM, contact Dealer technical support.
