Description and operation

Description

Installed in exhaust manifold, the Exhaust Gas Temperature Sensor (EGTS) #1 for WGT senses the temperature of exhaust gas flowing into the WGT.

Installed in Gasoline Particulate Filter (GPF) assembly, the Exhaust Gas Temperature Sensor (EGTS) #2 for GPF senses the temperature of exhaust gas flowing into the GPF.

When predetermined engine condition is met, ECM burns soot collected in GPF with exhaust gas. During this, the exhaust gas temperature is an important factor of engine condition.
