How to Diagnose and Solve P1655 PSP Switch Out of Self Test Range Issues
As a car enthusiast, there’s nothing more satisfying than rolling up your sleeves and getting your hands dirty to fix a car problem. Today, we’re going to tackle a common issue that many car owners face – the P1655 PSP Switch Out of Self Test Range error.
Understanding the P1655 PSP Switch Out of Self Test Range Error
Before we dive into the solution, let’s first understand what this error means. The P1655 error code is a Powertrain Diagnostic Trouble Code (DTC) that indicates a problem with the Power Steering Pressure (PSP) switch. This switch is responsible for detecting the fluid pressure in the power steering system. When the switch is out of the self-test range, it means that the pressure detected is either too high or too low.
What Causes the P1655 Error?
There are several reasons why your car might be showing the P1655 error. These include a faulty PSP switch, a damaged or disconnected wiring harness, or a problem with the power steering pump.
Diagnosing the P1655 Error
Now that we know what the P1655 error is and what causes it, let’s move on to diagnosing the problem.
Step 1: Check the PSP Switch
The first step in diagnosing the P1655 error is to check the PSP switch. This can be done by using a multimeter to measure the resistance of the switch. If the resistance is outside the specified range, the switch is faulty and needs to be replaced.
Step 2: Inspect the Wiring Harness
Next, inspect the wiring harness for any signs of damage or disconnection. If you find any damaged wires, they will need to be repaired or replaced.
Step 3: Check the Power Steering Pump
Finally, check the power steering pump for any signs of damage or wear. If the pump is faulty, it will need to be replaced.
Solving the P1655 Error
Once you’ve diagnosed the problem, it’s time to solve it. Here’s how:
Step 1: Replace the PSP Switch
If the PSP switch is faulty, replace it with a new one. This is a relatively simple task that can be done with basic tools.
Step 2: Repair or Replace Damaged Wires
If you found any damaged wires during your inspection, repair or replace them as necessary.
Step 3: Replace the Power Steering Pump
If the power steering pump is faulty, replace it with a new one. This is a more complex task that may require professional assistance.
Fixing the P1655 PSP Switch Out of Self Test Range error can be a bit challenging, but with the right knowledge and tools, it’s definitely doable. Remember, if you’re not comfortable performing these tasks yourself, it’s always best to seek help from a professional mechanic.
