The EBP sensor\u2019s main task is to monitor the exhaust back pressure helping PCM to keep things under control.<\/p>\n\n\n\n
As the sensor is located at the exhaust manifold, it is normal that exhaust soot clogs it over time.<\/p>\n\n\n\n
In this article, I have listed and described the 7.3 exhaust back pressure symptoms to keep an eye on them without much hassle.<\/p>\n\n\n\n
The most obvious signs of spotting a bad 7.3 EBP sensor are decreased fuel economy and poor performance of the engine.<\/p>\n\n\n\n
However, there are other symptoms too by which you can realize that the sensor has gone bad.<\/p>\n\n\n\n
Here, the symptoms will help you understand how to detect a bad 7.3 exhaust back pressure sensor.<\/p>\n\n\n\n
An obvious way to find out bad 7.3 exhaust back pressure sensor, you can use AE software. <\/p>\n\n\n\n
Read the pressure readings, and you would immediately know whether there is a problem or not. <\/p>\n\n\n\n
Suspecting something is wrong, you can take out the EBP sensor and tube. A carbon-clogged pipe will confirm your suspicion. <\/p>\n\n\n\n
Also, don\u2019t forget to see the error codes shown by the PCM. Here, let me tell you some common codes and their meaning related to the EBP sensor issue. <\/p>\n\n\n\n

2. Noticeably Low Fuel Efficiency<\/h3>\n\n\n\n
Another certain symptom is noticing very high fuel consumption. Compared to the previous engine performance and mileage, you will realize a huge difference. <\/p>\n\n\n\n
If the valve gets stuck somehow, it can affect the overall performance of the transmission. Reduction in power, less powerful acceleration, and hard starting are the results of becoming an EBP sensor faulty.<\/p>\n\n\n\n
3. No Power While Starting<\/h3>\n\n\n\n
You have got a clue from the last point. According to some Ford owners, their trucks don\u2019t start in the cold weather. <\/p>\n\n\n\n
After letting it warm up for 20 or 30 minutes, things get back to normal. This problem is not seen in the summer season. <\/p>\n\n\n\n
Those who are having severe issues can unplug the sensor and try to run the vehicle. <\/p>\n\n\n\n
Indeed, it will take longer than usual but it can solve the issue for the time being. <\/p>\n\n\n\n
Another situation was mentioned in the forums. Some people felt like having no authority over the acceleration. <\/p>\n\n\n\n
It is like dragging or driving in the 2nd<\/sup> gear although you are not.<\/p>\n\n\n\n

4. Excessive Smoke or Soot<\/h3>\n\n\n\n
Another possible situation is seeing excessive smoke or soot from the exhaust pipe. <\/p>\n\n\n\n
It doesn\u2019t occur when the combustion is proper. But the exhaust pressure valve becomes faulty and things go bad when the sensor becomes faulty.<\/p>\n\n\n\n
In the end, it causes black smoke and soot coming out of the exhaust which is a clear warning for checking the sensor.<\/p>\n\n\n\n
5. Loud Irritating Noise<\/h3>\n\n\n\n
In cold temperatures, truck owners face another problem besides hard starting. <\/p>\n\n\n\n
While accelerating lightly or maintaining the speed, it sounds like a bad vacuum leak. <\/p>\n\n\n\n
But putting down the pedal accelerating aggressively, the annoying sound goes away. <\/p>\n\n\n\n
Pro Tip<\/em><\/strong>: Some online communities may suggest that seeing engine lights turning on is another symptom of having a bad EPB sensor. But that doesn\u2019t happen. <\/em><\/p>\n\n\n\n
Even if you see engine lights while experiencing the above symptoms, it will mean that some other parts are also not functioning properly.<\/em><\/p>\n\n\n\n

What to Do When You Detect A Bad 7.3 Exhaust Back Pressure Sensor?<\/h2>\n\n\n\n
As there is no possible way to repair a faulty sensor, you have to replace it. <\/p>\n\n\n\n
Indeed, it is possible to clean the existing one and see whether it solves the problem or not. Otherwise, replacing is the only solution.<\/p>\n\n\n\n
Tip<\/em><\/strong>: To remove buildup on the sensor, you can use a shot of air inside the EBPS tube. Use a small pipe cleaner for cleaning the sensor. Be careful because a small puncture in the diaphragm of the EBP sensor can make it non-functional. <\/em><\/p>\n\n\n\n
Now, you can understand that taking the help of a mechanic adds another 100 bucks or so to the installation budget. <\/p>\n\n\n\n
Easily replace the bad one with a new EBP sensor at home using some basic tools. Follow the steps below and save some money. <\/p>\n\n\n\n
\n
- As the EBPS sits right in front of the high-pressure oil pump, you have to remove the plastic engine cover to gain access.<\/li>\n\n\n\n
- After that, carefully remove the electrical connection and the sensor. For removing the sensor, you have to use a 9\/16″ open-ended wrench to hold down the bolt and a 1″ deep socket to turn it. <\/li>\n\n\n\n
- Now, you will notice that the other end of the tube connects to the exhaust manifold at the passenger side. Here, use a 5\/8″ flare nut wrench for safe and easy removal.<\/li>\n\n\n\n
- Finally, repeat the whole process in reverse mode to install the new sensor.<\/li>\n<\/ul>\n\n\n\n
