OEM EGT Locations
The 2007.5 and newer light-duty diesel pickups are equipped with
OEM Exhaust Gas Temperature (EGT) sensors, all of which can be
monitored with the CS and CTS Devices.
Before a customer uses the vehicle’s OEM sensors for reading ex-
haust gas temperature, it’s extremely important that he/she be-
come educated about EGT sensor placement, and understand what
exactly to look for when using an EGT sensor on a diesel-powered
vehicle.
Edge Products was the rst company to integrate gauge screens
with their power modules giving customers the ability to monitor
EGTs and other vehicle parameters in real-time. Since the intro-
duction of the Attitude monitor Edge Products has taken a strong
stance on EGT probe placement. Edge Products has always recom-
mended that the EGT probe be placed in the exhaust manifold, in a
pre-turbo location simply because the manifold location gives the
best representation of combustion chamber temperatures. Other
locations downstream in the exhaust system do not accurately rep-
resent combustion chamber temperatures.
The 2008 and newer Ford Powerstroke 6.4L is factory-equipped with
an EGT sensor in the pipe prior to the high pressure turbo. This EGT
sensor accurately represents EGT temperatures in the combustion
chamber.
The 2007.5 and newer GM Duramax, and Dodge Ram 6.7 Cummins
do not have EGT sensors placed pre-turbo where the optimum read-
ings can be achieved. When items such as turbos, catalysts, NOX
lters, and particulate traps are introduced, temperatures can vary
in large margins due to the thermal energy stored/transferred by
these devices. This creates an environment that doesn’t represent
