Dd13 intake manifold pressure sensor location

The PCM uses this input, as well as others, to calculate the correct amount of fuel to inject into the cylinders. The MAP sensor measures the absolute pressure inside the intake manifold of the engine.

At sea level, atmospheric pressure is about When the engine is off, the absolute pressure inside the intake equals atmospheric pressure, so the MAP will indicate about At a perfect vacuum, the MAP sensor will read 0 psi.

When the engine is running, the downward motion of the pistons create a vacuum inside the intake manifold For the purposes of engine control, when a technician says vacuum, what they are really saying is pressure that is less than atmospheric pressure.

A failed MAP sensor has serious implications on fuel control, vehicle tailpipe emissions and fuel economy. Symptoms of a bad or failing MAP sensor include:. This results in an increase of fuel being injected into the engine. This, in turn, decreases your overall fuel economy. It also increases the amount of hydrocarbon and carbon monoxide emissions from your vehicle to the surrounding atmosphere. Hydrocarbons and carbon monoxide are some of the chemical components of smog. The PCM responds by reducing the amount of fuel being injected into the engine.

By reducing the fuel into the engine, combustion chamber temperatures are increased. This increases the amount of NOx oxides of nitrogen production within the engine.

NOx is also a chemical component of smog. A bad MAP sensor will cause your vehicle to fail an emissions test.

This engine is a used replacement engine that was dropped in a few weeks. When the code sets, the engine derates.

Initially when I diagnosed it, I pulled the EGR differential pressure sensor off to find out it was plugged. I swapped out the sensor and mounting tube with the ones from the original engine. The engine will not ramp up to for the test and the test quickly fails. Here is a PDF of the fault code data when I last set the code on a road test. I pulled the outlet tube off the EGR cooler and stuck my borescope inside.

The cooler is not plugged, at least not at the outlet. Can you do an air mass adaptation in service panel? Truck must be warm I believe. Check the EGR flap on the manifold by the turbo, shaft could have broke and the linkage is just moving. Seen this one time. Check the itv seen these go bad with no cel for it. All the suggestions are good but the truck is on a back burner as usual while I'm waiting parts to fix a coolant leak on it.

Once I get the coolant leak fixed, we may just send it to the dealer. All we had to do was replace the engine with a customer supplied used engine. I don't want to waste a lot of time trying to figure out if the used engine has issues or not.

Find Trucking Jobs. N14 barometric pressure sensor Discussion in ' Freightliner Forum ' started by cdubJul 27, Jul 27, 1. I need some help with my n14 redtop celect plus cummins motor in a 99 freightliner.

Yesterday when I was shiftin from 3rd to 4th gear while turning at an intersection I noticed a miss in the motor like it was going to run out of fuel along with loss in power. I checked the guages and noticed that the check engine light was flashing.

The ac was on and the engine fan was running at the time. It was very brief and I continued to drive. Once I had a chance to have the code read it came up barometric pressure sensor below level 7 times. Im not sure what that means and several of the shops I have went to said they never heard of it.

Any help with this would be much appreciated. I can provide engine model number if needed. Yes, let employers and TruckersReport text me with new opportunities, job alerts and other career information to the number I provided.

There is no charge for this service, but standard message and data rates may apply. Jul 27, 2. My guess is there are two sensors in the intake manifold, the one on the side is manifold temp and the one at the back is pressure.

Sounds like the back one is going bad. AutocarJul 27, Jul 27, 3. What was the code? Flashing yellow or red lamp? Jul 27, 4. Dont recall the code number. It was flashing yellow. Code was inactive when I hooked the scanner up. I called peterbilt dealer just ask the question and the told me to unplug sensor on the bottom of the block on the driver side.

I did and the code went active. They said ok we got the sensor you need. I went to pick it up and they sold me the ambient tempture sensor but the sensor I unplugged was and oil sensor.

I decided that they did not know what they were talking about and when I unplugged the oil sensor it was just a coincidence that the code went active. There was the barometric pressure sensor code and low coolant level code that were inactive. I think the coolant one was never cleared from when the coolant sensor was going bad. Jul 28, 5. This is getting way too hairy already. If you have the code and what type scanner you used to retrieve codes we can get on track. Jul 28, 6.If you shop at Amazon.

The attached. No immediate reference to MAP seen. You do not have the required permissions to view the files attached to this post. It says the fuel pressure sensor: "uses intake manifold vacuum as a pressure reference". Since there appears no manifold pressure sensor, it may use a mechanical method to measure fuel pressure relative to intake.

The fuel rail pressure and temperature sensor: measures the pressure and temperature of the fuel in the fuel supply manifold and sends these signals to the PCM.

The MAF sensor: uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool. The HO2S: creates a voltage signal dependent on exhaust oxygen content. The catalyst monitor sensor: monitors oxygen content after it flows through the catalytic converter. The KS: is used to detect engine detonation spark knock. All of the other sensors are completely irrelevant, unless my PCM needs to be flashed or something.Also See for D13 Installation manual - 36 pages.
