Do I need an EGT sensor?

The exhaust gas temperature (EGT) pyrometer can be one of the most important gauges on a turbo-diesel-powered vehicle. It can warn the driver of situations that are potentially damaging to the engine, and it can also be used as a guide for optimizing fuel economy. Diesel engines are not indestructible.

What thread is a EGT sensor?

EGT probes are usually NPT (pipe threads) – most likely 1/8″ NPT. It is a tapered thread that does not require any kind of sealant, which makes it ideal for hot exhaust systems.

Where should I put my EGT probe?

The probe should be installed in the exhaust manifold closest to the exhaust outlet at the head (this is the closest physical location to the exhaust valve). EGT probe placement close to the exhaust valve isn’t always easy.

What does the EGT gauge measure?

In a piston engine, EGT is a measurement of the temperature of the exhaust gases at the exhaust manifold. As the temperature of the exhaust gas varies with the ratio of fuel to air entering the cylinders, it can be used as a basis for regulating the fuel/air mixture entering the engine.

What EGT is too high?

The absolute maximum safe EGT range is debatable. Our universal rule of thumb, regardless of engine make/model/year, is to not exceed 1250° F and not to operate in the 1200° F – 1250° F range for an extended period of time.

How do you test a DPF sensor?

If everything passes physical inspection, you can test the DPF differential pressure sensor using a multimeter set to 20V and a pressure gauge. With the battery on and engine off, connect the multimeter ground to the negative battery terminal and run a quick plausibility by checking the voltage of the battery.

How do you lower your EGT?

be putting in a lot of fuel without pushing enough air through. A free flowing 4″ exhaust helps a lot to lower EGTs. the EGTs up quite rapidly.

How many EGT sensor does a 6.7 have?

There are a total of 4 EGT sensors on the 6.7L Powerstroke.

What should EGT be at idle?

The longer it idles the cooler it will get, but no cooler than around 250* if the engine is at full operating temperature unless its VERY cold outside. When the weather is warmer summer then typically EGT’s will stay more around 300-325* depending on how long its been idling.

What is considered high EGT?
