Product Function
The 243222 Pressure Sensor plays a vital role in the operation of various electric and gasoline airless sprayer models. It is strategically connected between the high-pressure filter and the control board of the sprayer.
The primary function of this transducer is to send a precise signal to the control board. This signal provides the control board with crucial information regarding the sprayer's internal pressure, allowing it to accurately determine when the sprayer has reached its maximum operating pressure. This ensures consistent performance and helps prevent over-pressurization.

Installation Guide
This section outlines the steps for replacing or installing the 243222 Pressure Transducer Sensor. Proper installation is crucial for the correct operation of your airless sprayer.
When to Replace the Sensor:
The 243222 pressure transducer sensor typically needs replacement if the sprayer's display panel shows "CODE 03" or if the control board's LED blinks three times. These indicators suggest a malfunction in the pressure sensing system.
Installation Steps:
- Step 1: Power Down and Unplug
Before beginning any work, turn off the power to your airless sprayer and unplug the power cord from the electrical outlet. This is a critical safety measure to prevent electrical shock.

- Step 2: Unplug the Old Transducer
Locate the existing pressure transducer sensor. Carefully unplug the cable connected to the old transducer from the control board. You may need to remove the control box cover to access it.

- Step 3: Install the New Transducer
Install the new 243222 pressure transducer sensor by connecting its cable to the corresponding port on the control board. Ensure the connection is secure.

- Step 4: Verify Operation
After installation, reassemble any covers, plug in the sprayer, and turn on the power. Check the display board. If no error code (like CODE 03) is showing, it indicates the new transducer sensor is functioning correctly.

Operating Principles
Once installed, the 243222 Pressure Transducer Sensor operates continuously to monitor the pressure within your airless sprayer system. It translates the physical pressure into an electrical signal that is sent to the sprayer's control board.
The control board uses this signal to regulate the pump's operation, maintaining a consistent spray pressure for optimal paint application. A properly functioning transducer ensures that the sprayer delivers paint at the desired pressure, preventing issues like inconsistent spray patterns or premature wear on other components.
Maintenance
The 243222 Pressure Transducer Sensor is designed for durability and long-life. Regular maintenance of your overall airless sprayer system will help prolong the life of all components, including the transducer.
- Cleaning: Always clean your airless sprayer thoroughly after each use, following the manufacturer's guidelines. This prevents paint buildup that could affect pressure readings or damage components.
- Inspection: Periodically inspect the transducer and its cable for any signs of wear, damage, or corrosion. Ensure the connections are secure.
- Storage: Store your sprayer and components in a clean, dry environment to prevent damage from moisture or extreme temperatures.
If you suspect the transducer is malfunctioning, refer to the "Troubleshooting" section or consult a qualified service technician.
Troubleshooting
If your airless sprayer is exhibiting issues related to pressure regulation or error codes, the pressure transducer may be a contributing factor. Here are common troubleshooting steps:
- Error Code 03: If your sprayer's display panel shows "CODE 03", or the control board's LED blinks three times, this is a direct indicator that the pressure transducer sensor needs to be replaced. Follow the "Installation Guide" to replace the sensor.
- Inconsistent Pressure: If the sprayer is delivering inconsistent pressure, first check for common issues like clogged filters, worn spray tips, or air in the system. If these are ruled out, a faulty transducer could be sending incorrect signals to the control board.
- No Pressure: Ensure all connections are secure and there are no leaks in the system. If the sprayer motor runs but no pressure builds, and other components are confirmed functional, the transducer or control board might be at fault.
- Visual Inspection: Inspect the transducer and its wiring for any visible damage, corrosion, or loose connections.
If troubleshooting steps do not resolve the issue, it is recommended to consult a professional service technician or refer to your specific Graco sprayer's service manual.
