What does the P1550 code mean?

The P1550 code is a diagnostic trouble code (DTC) that indicates a problem with the power steering pressure (PSP) switch. The PSP switch is responsible for monitoring the pressure of the power steering system and relaying that information to the car’s computer.

When the PSP switch detects an issue with the power steering system pressure, it will send a signal to the car’s computer, which will generate the code. In some cases, the code may also be accompanied by the “check engine” light on the dashboard.

What causes the P1550 code?

All right, now that we’ve cleared that up regarding the consequences that this code may have, it’s time to get serious. Let’s start by giving you a brief overview of each of the possible causes of the P1550 code:

Faulty PSP switch

A faulty or damaged PSP switch may not accurately detect the pressure of the power steering system, which can cause the code to be triggered. In this case, the switch will need to be replaced.

Low-power steering fluid

Low power steering fluid levels can cause a drop in pressure in the power steering system, which can trigger the PSP switch and generate the P1550 code. Simply adding more power steering fluid may fix the problem.

Worn power steering pump

A worn or damaged power steering pump can also cause low pressure in the power steering system, which can trigger the PSP switch. In this case, the power steering pump will need to be replaced.

Damaged power steering hoses

Damaged or leaking power steering hoses can also cause a drop in pressure in the power steering system, triggering the PSP switch and generating the code. The damaged hoses will need to be replaced.

Which car models does the P1550 code affect the most?

While the P1550 code can affect any car with a power steering system, some models are more prone to experiencing this issue. This is often due to the design of the power steering system or the quality of the components used, so let’s take a closer look at these models:

• Chevy Silverado: This pickup truck has been known to experience issues with its TAC system, resulting in the code being triggered.
• Honda Civic: This car is often said to be prone to the code due to its issues with the power steering pump.
• Honda Accord: Like its compact sibling, the Accord is yet another Honda model that’s prone to the code P1550 due to a faulty steering pump and hoses.

How to diagnose the P1550 code

There are several potential issues that could be behind the code P1550 in your car. So, here’s a list of potential steps you can take to diagnose the code:

Check the power steering fluid

One of the best ways of determining the problem behind the code is to check the power steering fluid level and top it up if necessary. If there are any suspected leaks, you should refer to a trusted mechanic to examine the system and find the leak’s location.

Inspect the power steering pump

The pump is what gets the steering fluid going within the power steering system so it’s natural to look into this component in case the problem seems to persist.

Test the PSP switch

Another way of determining the cause behind this code is by using a multimeter to test the PSP switch and see if there’s enough voltage put into it to maintain the proper pressure of the power steering system.

How to fix the P1550 code

Once the cause of the P1550 code has been determined, there are several potential fixes that we recommend you to take, so let’s take a closer look into every possible solution:

Replace the power steering switch

This switch is responsible for sensing changes in pressure within the power steering system and communicating this information to the vehicle’s computer. If the switch is faulty or malfunctioning,

Replace the power steering pump

Another way of fixing this code is by repairing or replacing the power steering pump. This pump pushes the fluid through the hydraulic system responsible for the power steering system’s operation, so replacing it could solve the issue and remove the code.

Add the power steering fluid

Finally, if there’s a lack of power steering fluid somewhere in the system or if there’s a leak, you can top up the fluid to fix the situation and clear the code.

How to prevent the P1550 code

Routine maintenance and proper care of your car’s power steering system can help prevent the P1550 code from occurring. Some preventative measures you can take include:

• Checking power steering fluid levels regularly and topping off as needed
• Having your power steering system inspected and serviced regularly by a qualified mechanic
• Avoiding rough or aggressive driving that can put added strain on the power steering system

By following these tips, you can help keep your car’s power steering system in good working order and avoid the headaches of the P1550 code.

Our take

In the end, it turns out that the code P1550 can be pretty bad for your car’s steering system and it may even lead to a complete loss of the power steering function. So, it’s essential to fix it on time and we think that this guide holds all the answers to the questions you may have about diagnosing and removing the code.
