The MAP sensor on the 2007.5-2015 Dodge with 6.7L Cummins Engine is located on the intake horn. The intake horn is on the driver’s side with the MAP sensor placed on the side of the intake horn closest to the firewall.
Typically found in fuel injected engines, the manifold absolute pressure (MAP) sensor is one of the sensors an engine control module (ECM) uses to calculate fuel injection for optimal air-fuel ratio by continuously monitoring intake manifold pressure information.
What does the MAP sensor do on a 6.7 Cummins?
Your Cummins 6.7L Diesel Engine uses the MAP sensor as an aid to precisely control fuel injection for the best engine performance possible based on the current conditions.
The assembly uses two NOx sensors: the first sensor (referred to as NOx sensor 1) is located near the turbo downpipe and measures engine-out NOx. The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst.
Where are the sensors on a 6.7 Cummins? – Related Questions
What happens if NOx sensor fails?
The NOx sensors tells the ECU how much DEF should be injected into the exhaust before it enters the SCR. If the sensors are faulty, you’ll likely see increased DEF consumption and fuel spending, alongside erratic or unstable idling.
Is NOx sensor same as o2 sensor?
Is the NOx sensor the same as a Lambda (Oxygen) Sensor? The short answer is NO. While one component measures oxygen gas, the other measures nitrogen oxide gas. Both are valuable in their own way.
What is the difference between downstream and upstream NOx sensor?
NOx Sensor for NOx aftertreatment system
The sensor located upstream of the SCR catalyst directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection. The NOx sensor downstream of the SCR catalyst is used to monitor the performance of the catalyst.
Where is the downstream NOx sensor located?
NOx Sensor, Position 2, Downstream
This NOx sensor is located downstream in the exhaust system.
Where is the inlet NOx sensor located?
Is NOx sensor 1 upstream or downstream?
Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.
Go to the System menu, select Engine, then choose the specifics for your vehicle and go to Functional Tests, followed by Special Functions. At the next screen pick Adaptations then scroll down to find Reset Learned Values Of NOx Sensor Upstream And Downstream Of SCR Catalytic Converter.
How do you tell if a sensor is upstream downstream?
Is bank 2 up or downstream?
Anytime the code reader says sensor 2, it is referring to the downstream. If you need further assistance with your oxygen sensors, then seek out a professional, such as one from Your Mechanic, to help you.
How do I know if my downstream O2 sensor is bad?
Signs a Vehicle has a Bad O2 Sensor
Check Engine Light Comes On.
Noticeable Loss of Fuel Efficiency.
Sulfur or ‘Rotten Egg’ smell from Exhaust.
Black smoke from exhaust.
Emission levels reach high levels.
Your engine hesitates, skips, begins bucking or has power surges.
Can I use the same O2 sensor for upstream and downstream?
They both function the same but are different enough that they cannot be swapped.
Which side of the engine is Bank 1?
How can you tell the difference between bank 1 and bank 2?
What is Bank 1 and Bank 2? Bank 1 and bank 2 simply refer to either side of the engine. Check your owner’s manual or a service manual for a positive location of bank 1 and bank 2. Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.
