P1910 Pressure Control Solenoid “C” Intermittent Short

How to Diagnose and Solve P1910 Pressure Control Solenoid “C” Intermittent Short 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. One such issue that can be a real head-scratcher is the P1910 Pressure Control Solenoid “C” Intermittent Short. But don’t worry, I’m here to guide you through the process of diagnosing and solving this issue.

Understanding the P1910 Code

Before we dive into the solution, let’s first understand what the P1910 code means. This code is triggered when the Engine Control Module (ECM) detects an intermittent short in the pressure control solenoid “C”. This solenoid is responsible for controlling the hydraulic pressure in the automatic transmission based on the power output of the engine.

What Causes the P1910 Code?

The P1910 code can be caused by several factors, including a faulty pressure control solenoid, damaged wiring, or a malfunctioning ECM.

Diagnosing the P1910 Code

Step 1: Visual Inspection

The first step in diagnosing the P1910 code is a visual inspection. Check the wiring and connectors for any signs of damage or corrosion.

Step 2: Use a Diagnostic Tool

Next, use a diagnostic tool to read the fault codes from the ECM. This will help you identify if the P1910 code is present and if there are any other related codes.

Step 3: Test the Pressure Control Solenoid

To test the pressure control solenoid, you’ll need a multimeter. If the solenoid is faulty, it will need to be replaced.

Solving the P1910 Code

Step 1: Replace the Pressure Control Solenoid

If the pressure control solenoid is faulty, replace it with a new one. Make sure to follow the manufacturer’s instructions for replacement.

Step 2: Repair or Replace Damaged Wiring

If you find any damaged wiring during your visual inspection, repair or replace it as necessary.

Step 3: Reset the ECM

After replacing the solenoid and repairing any damaged wiring, reset the ECM to clear the P1910 code.


Fixing a P1910 Pressure Control Solenoid “C” Intermittent Short issue may seem daunting, but with the right tools and a bit of patience, you can do it yourself. Remember, always take safety precautions when working on your vehicle and don’t hesitate to seek professional help if you’re unsure about any step in the process.


1. Can I drive my car with a P1910 code?

While your car may still be drivable with a P1910 code, it’s not recommended. The issue can lead to poor fuel efficiency, transmission slipping, or even complete transmission failure.

2. How much does it cost to fix a P1910 code?

The cost to fix a P1910 code can vary depending on the cause. If you need to replace the pressure control solenoid, it can cost anywhere from $200 to $600 for parts and labor.

3. Can I fix a P1910 code myself?

Yes, if you’re comfortable with car repairs and have the necessary tools, you can diagnose and fix a P1910 code yourself. However, if you’re unsure, it’s best to seek help from a professional mechanic.
