ECT2 monitors secondary cooling system temperature, which affects EGR cooler temperature and performance.
The EGR cooler bypass valve alters the flow of EGR gases to increase the temperature of the gas at low engine speeds. The vacuum controlled…
During some operating conditions the EGR cooler is bypassed.
The exhaust gas enters through the EGR valve and then goes through the EGR bypass valve. As the exhaust gas enters the EGR cooler, it…
The second part of the EGR cooler is cooled by the powertrain secondary cooling system. An internal air-to-coolant heat exchanger absorbs heat from the exhaust…
The first part of the EGR cooler is cooled by the primary cooling system. An internal air-to-coolant heat exchanger absorbs heat from the exhaust gases…
The EGR system uses an EGR cooler after the EGR valve. This keeps the EGR valve cleaner than previous engines. The EGR cooler is located…
The EGR valve receives a duty cycle signal from the PCM and sends a variable voltage signal from the Exhaust Gas Recirculation Valve Position (EGRVP)…
The EGR system allows cooled (inert) exhaust gases to re-enter the combustion chamber, which lowers combustion temperatures and Oxides of Nitrogen (NOx) emissions. EGR system…
