The P2517 code indicates that the A/C refrigerant press sensor B circuit has low voltage.
The powertrain control module has found that a reading from the A/C refrigerant pressure sensor is out of the normal and acceptable limitations allowed by the manufacturer.
The following are some of the most common causes of the P2517 code:
When you have the P2517 code stored in your vehicle, it generally means that your air conditioning system is not operating at all. You will likely notice that the malfunction indicator light is on as well. The on light for the A/C might flash as well.
A mechanic will connect an OBD-II scanner to the vehicle’s computer system and access data about the vehicle. They will use this information to help with their diagnosis. In addition to gathering the data, they will reset the codes and then drive the vehicle. The reason for this is simple. They want to make sure that the code was not set accidentally. If the P2517 code returns, then they know that they have a problem with the A/C.
Many technicians who see this code immediately think that the problem must be that there is not enough refrigerant in the system, so they add more. This could be a mistake though. If they add more refrigerant when it isn’t actually needed, it could cause the system to fail catastrophically. It is important that the technicians make a thorough investigation to find the true cause of the problem.
Nobody likes the thought of sitting in a hot car. Today, air conditioning is a necessity, so if your A/C stops working, it can be a huge inconvenience. Imagine sitting in traffic in a hot and miserable car. Getting to and from work or even the store could be a problem, and going on a longer trip is out of the question. While you might not think that air conditioning is a big deal right now, as soon as the temperatures start to climb, you will be wishing that you had A/C. Take your vehicle to a mechanic now to get it diagnosed and cared for properly. You might need refrigerant, or there might be other issues with the air conditioning that you would not be able to handle on your own.
The following are repairs that mechanics may use when they are trying to fix the P2517 code:
Remember that only trained and qualified professionals should be adding refrigerant and working on the air conditioning system. They have the tools and equipment needed to fix the unit. When you have no air conditioning, the summers are going to be miserable. If you have been having issues and this code is present, don’t put off getting it fixed. Take it to a mechanic who can provide you with a proper diagnosis and repair.
