P0551 is a diagnostic trouble code (DTC) for "Power Steering Pressure Sensor Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
The definition of the P0551 trouble code is that the power steering pressure sensor circuit range/performance is compromised or malfunctioning.
When this code set it means that the powertrain control module did not receive the correct voltage input signal from the power steering pressure sensor. Most of the time, this issue will occur at lower vehicle speeds. Some types of vehicles will need to have multiple failure cycles for this to cause the Check Engine light to come on. However, after the first failure, the trouble code should be stored in the onboard computer.
Some of the most common causes of the P0551 code are as follows:
Here are some of the most common symptoms that drivers noticed with the P0551 trouble code:
When they are diagnosing the P0551 code, the mechanic will record the information stored in the onboard computer with their scanner. They will then reset the code and test the vehicle to see if the code returns. If it is not a false alarm, they will then try to pinpoint the actual problem with the vehicle and make the necessary repairs to remove the code.
Because of the possibility of the engine stalling when driving and turning at low speeds, many will mistakenly blame the idle air control system for the issue rather than the power steering pressure sensor circuit and issues with the power steering system.
It is always a good idea for mechanics to fully diagnose and explore the potential problems with the vehicle so they can find the exact cause and repair it properly. One of the first things the mechanic will likely want to consider is the power steering fluid. They want to make sure there is enough, and that it is clean.
The P0551 code can be quite problematic. In many cases, the vehicle is going to suffer from some serious performance issues. In addition to possibly having a power steering fluid leak, it is also possible that the fuel economy for the vehicle is not quite as robust as it used to be. One of the most troubling aspects of the P0551 code is that those vehicles that have the code stored often have trouble when it comes to stalling out during low-speed vehicle maneuvers. This has the potential to be very dangerous, therefore getting the code fixed and the vehicle repaired as quickly as possible is essential.
The following are some of potential repairs that can be used to fix the P0551 code:
Since these issues presented by the P0551 code can be dangerous, it is important to have them taken care of immediately. Get the problem checked out by a certified mechanic as quickly as you can to reduce the risk of further problems.
