No. 2 EXHAUST GAS TEMPERATURE SENSOR CHECK



 1.Disconnect the No. 2 exhaust gas temperature sensor (catalyst temperature) connector.
2.Measure resistance between terminal No. 1 and No. 2.
Standard value: Approximately 220 Ω (at 25°C)
note This sensor has the characteristic that the resistance value increases as the temperature increases.
3.If the value deviates largely from the standard value, replace the No. 2 exhaust gas temperature sensor [Refer to Diesel Particulate Filter (DPF) Removal and Installation ].
