P1755 Pressure Control Solenoid “A” Short Circuit

How to Diagnose and Solve P1755 Pressure Control Solenoid “A” Short Circuit Issues


Are you a car enthusiast who loves to get your hands dirty? Or perhaps you’re a DIYer who enjoys the satisfaction of fixing things yourself? If so, you’re in the right place. Today, we’re going to delve into the world of car diagnostics, specifically focusing on the P1755 Pressure Control Solenoid “A” Short Circuit issue.

Understanding the P1755 Code

First things first, let’s understand what the P1755 code means. This code is a generic powertrain diagnostic trouble code (DTC), which indicates a problem with the pressure control solenoid “A”. The solenoid controls the hydraulic pressure in the automatic transmission, and a short circuit in this solenoid can lead to various transmission issues.

What Causes the P1755 Code?

The P1755 code can be triggered by several factors. These include a faulty pressure control solenoid, damaged or corroded wiring, a malfunctioning transmission control module, or even low transmission fluid levels.

Diagnosing the P1755 Code

Now that we know what the P1755 code is and what causes it, let’s move on to diagnosing the issue.

Step 1: Check the Transmission Fluid

The first step in diagnosing the P1755 code is to check the transmission fluid. Low or dirty transmission fluid can cause the pressure control solenoid to malfunction.

Step 2: Inspect the Wiring

Next, inspect the wiring and connectors for any signs of damage or corrosion. Damaged wiring can cause a short circuit in the pressure control solenoid.

Step 3: Test the Pressure Control Solenoid

If the transmission fluid and wiring are in good condition, the next step is to test the pressure control solenoid. This can be done using a multimeter.

Solving the P1755 Code

Once you’ve diagnosed the issue, it’s time to solve it.

Step 1: Replace the Transmission Fluid

If the transmission fluid is low or dirty, replace it with new fluid. This can often solve the P1755 code.

Step 2: Repair or Replace Damaged Wiring

If you find any damaged or corroded wiring, repair or replace it as necessary.

Step 3: Replace the Pressure Control Solenoid

If the pressure control solenoid is faulty, it will need to be replaced. This is a job best left to a professional, as it involves disassembling the transmission.


Diagnosing and solving the P1755 Pressure Control Solenoid “A” Short Circuit issue may seem daunting, but with a little patience and the right tools, it’s a task that can be tackled by any DIYer. Remember, if you’re ever in doubt, it’s always best to consult with a professional.


1. Can I drive my car with the P1755 code?

While it may be possible to drive with the P1755 code, it’s not recommended. The issue can lead to serious transmission problems if not addressed promptly.

2. How much does it cost to fix the P1755 code?

The cost to fix the P1755 code can vary greatly depending on the cause of the issue. It can range from a simple fluid change to a more costly solenoid replacement.

3. Can I fix the P1755 code myself?

Yes, if you’re comfortable with car maintenance and have the necessary tools, you can diagnose and fix the P1755 code yourself. However, if the issue involves replacing the pressure control solenoid, it may be best to seek professional help.
