The exhaust gas temperature sensors are installed before and after the GPF catalyst to sense the exhaust gas temperature.

A thermistor built into the sensor changes its resistance value according to the exhaust gas temperature. The lower the exhaust gas temperature, the higher the thermistor resistance value. The higher the exhaust gas temperature, the lower the thermistor resistance value.

The exhaust gas temperature sensor is powered by a 5 V supply from the THCI and THCO terminals of the ECM, via resistor R.

Resistor R and the exhaust gas temperature sensor are connected in series. When the resistance value of the exhaust gas temperature sensor changes in accordance with the exhaust gas temperature, the voltage at terminals THCI and THCO also changes. The No. 1 exhaust gas temperature sensor monitors the temperature upstream of the GPF catalyst. The No. 2 exhaust gas temperature sensor monitors the rise in temperature of the GPF catalyst. The ECM uses 2 sensors in order to detect loss of function of the GPF.

HINT:

·

Sensor 1 represents the sensor located upstream of the GPF catalyst.

·

When DTC P054411 and P054415 is output, check the exhaust gas temperature indicated by "Powertrain / Engine / Data List / Exhaust Temperature B1S1" using the GTS.

Reference:

Condition	Exhaust Temperature B1S1	No. 1 Exhaust Gas Temperature Sensor Condition
Idling with warm engine	Constant at between 50 and 400°C (122 and 752°F)	Normal
	0°C (32°F) or less	Open circuit
	1000°C (1832°F) or higher	Short circuit

The ECM constantly monitors the output voltages from the No. 1 exhaust gas temperature sensor in order to detect problems with the sensor.

No. 1 exhaust gas temperature sensor range check (low voltage) (P054411):

If the output voltage of the No. 1 exhaust gas temperature sensor remains below 0.09 V for 3 seconds or more during engine operation, the ECM illuminates the MIL and stores a DTC.

No. 1 exhaust gas temperature sensor range check (high voltage) (P054415):

If the estimated GPF upstream exhaust gas temperature is 100°C or more during engine operation and the output voltage of the No. 1 exhaust gas temperature sensor remains at more than 4.95 V for 10 seconds or more, the ECM illuminates the MIL and stores a DTC.

1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON.

4.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

5.

Turn the ignition switch off and wait for at least 30 seconds.

6.

Start the engine [A].

7.

Idle the engine for 3 seconds or more [B].

8.

Turn the GTS on.

9.

Enter the following menus: Powertrain / Engine / Trouble Codes [C].

10.

Read the pending DTCs.

HINT:

·

If a pending DTC is output, the system is malfunctioning.

·

If a pending DTC is not output, perform the following procedure.

11.

Enter the following menus: Powertrain / Engine / Utility / All Readiness.

12.

Input the DTC: P054411.

13.

Check the DTC judgment result.

GTS Display	Description
NORMAL	· DTC judgment completed · System normal
ABNORMAL	· DTC judgment completed · System abnormal
INCOMPLETE	· DTC judgment not completed · Perform driving pattern after confirming DTC enabling conditions

HINT:

·

If the judgment result is NORMAL, the system is normal.

·

If the judgment result is ABNORMAL, the system has a malfunction.

·

If the judgment result is INCOMPLETE, perform steps [A] through [C] again.

·

[A] to [C]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

·

When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
