Finding The 6.7 Cummins Sensor Locations

Curious to know about the 6.7 Cummins sensor locations? We are here to provide you with all the necessary information. All sensors are there under the hood to help your vehicle engine perform its best!

Modern problems need modern solutions. Thus, the automotive sensors enter the scene. The sensors measure everything that is happening in and around the engine and signal the ECM according to them. Using the data from the sensors, the ECM then decides the thoroughly calculated actions.

One must know the whereabouts of their vehicle’s sensors. Because simple damage in the sensors may lead to decreased performance and even an engine failure of the vehicle. Knowing the sensor locations will enable them to clean, check, and replace them when it is necessary.

6.7 Cummins Sensor Locations

A numerous number of sensors are working all the time when the engine is running. Each of them has different data to collect and then send to the computer.

Let’s have a look at some of the important sensors of you can find in your Cummins 6.7 engine.

Crank sensorBottom front side of the engine
Cam sensorAttached to the crank sensor with a pipe
MAF sensorRight side of the air inlet
IAT sensorUpper-left intake manifold. Inside second intake runner
EGT sensorOn the exhaust system
MAP sensorDriver’s side of the intake manifold.
NOx sensorMounted to the front side, near to the rear bumper
Exhaust Pressure sensorBesides the exhaust system
Coolant temperature sensorBelow the EGR tube

6.7 Cummins Crank Sensor Location

The crank sensor of the 6.7 Cummins is one of the easiest sensors to find. It is attached to the bottom front part of the engine. If you look from below, you can see the sensor very clearly by the balancer.

The crank sensor notifies the ECM about the position, movement, and speed of the crankshaft. This information helps to determine the time and amount of fuel injection.

6.7 Cummins CAM Sensor Location

The cam sensor is a bit tough to find. This sensor is located above the crank sensor. The crank and cam sensor are connected together through a pipe. You’ll find the cam sensor if you follow the pipe attached to the crank sensor.

The cam sensor works together with the crank sensor by giving information about the crankshaft. It informs the computer which cylinder is firing, which allows the synchronization of the fuel injectors and ignition.

6.7 Cummins MAF Sensor Location

Well, the mass airflow sensor (MAF) is attached to the right side of the air inlet which is on the passenger’s side.

This MAF sensor detects the amount of airflow that comes to the engine and signals the ECM. With this information, the ECM decides how much fuel is to be injected and how long.

6.7 Cummins IAT Sensor Location

The Intake air temperature or IAT is situated in the upper-left side of the intake manifold. You can find it inside the second intake runner.

IAT sensor signals the ECM by assessing the temperature and the density of the air. Based on this data, the ECM initiates the accurate amount of spark and fuel injection into the engine. This process helps the engine to start smoothly.

6.7 Cummins EGT Sensor Location

The EGT sensor, the exhaust gas temperature sensor, is situated in the exhaust system.

This sensor keeps the exhaust gas temperature of the engine in check. The absence of this sensor may make your engine hot and risky.

6.7 Cummins Temp Sensor Location

In Cummins 6.7, the coolant temperature sensor is placed below the EGR tube.

The temp sensor allows the fuel management system to get data about the temperature of the engine. Knowing that helps the system to determine the timing and amount of the fuel injection.

6.7 Cummins MAP Sensor Location

The MAP sensor in 6.7 Cummins is on the driver’s side of the intake manifold. It looks like a small black box.

The manifold absolute pressure (MAP) sensor calculates the air pressure for the ECM so that it can supply the right amount of air-fuel mixture to the engine.

6.7 Cummins Exhaust Sensor Locations

The exhaust pressure sensor is placed right beside the exhaust system on a 6.7 Cummins.

This sensor compares the before and after the pressure of the exhaust that runs through the filter. So, it will let you know if the filter needs any repair or replacement.

6.7 Cummins NOx Sensor Location

There are two NOx sensors. The first one is mounted to the front of the vehicle. The second one can be found near the bumper. It’s mounted to the passenger’s side frame rail.

The NOx sensor helps the SCR assess the NOx gas that comes out of the engine and keep the emission regulations going. The SCR determines how much area should be injected based on this information.

Frequently Asked Questions (FAQs)

Where is the MAF sensor on a 6.7 Cummins?

Among the other 6.7 Cummins sensor locations, the MAF sensor is located on the right side or the passenger’s side of the air inlet. MAF detects the airflow pressure and sends the data to the ECM. ECM uses these data to determine the amount and timing of fuel injection.

What does the MAP sensor do on a 6.7 Cummins?

The job of the MAP sensor is to measure the air pressure and send the results to the ECM. The manifold air pressure sensor enables the ECM to have control over the amount and timing of air-fuel mixture injection.

How do you clean a 6.7 Cummins map sensor?

Detach the sensor carefully from the vehicle. Place the sensor on a plain surface. Take a soft cleaning cloth, preferably the ones used for cleaning electrical parts. Use an electrical parts cleaner to clean the sensor. It will clean the sensor most effectively.

What is MAF sensor?

MAF sensor refers to the mass airflow sensor. The mass airflow sensor detects the amount of airflow inside the engine and sends the result to the ECM. Then the ECM can measure the amount and timing of fuel injection accurately.

Wrap up

Sensors are very important parts of your vehicle. The sensors collect different kinds of data to ensure a trouble-free and comfortable driving experience.

If somehow any sensor is damaged, it will throw your vehicle at the risk of malfunctioning, poor performance, and even engine damage in some cases.

Therefore, it is very important to know your 6.7 Cummins sensor locations so that you can take care of them when they need it. Often a dirty sensor can cause trouble. So it’s necessary to check on the sensors once in a while to clean them and look for any potential damage.

The early repair and replacement of the sensor will keep your engine safe from any major problems. Know the sensors and where to find them for a better understanding of your vehicle and for a longer service!
