Need high-accuracy, mid-to-low pressure tracking without the premium brand price tag? This 30 PSI Stainless Steel Pressure Transducer is the ultimate budget-friendly solution for tracking vital automotive data. It is perfectly sized for monitoring wastegate dome pressure (CO2 or advanced boost control systems), engine crankcase pressure/vacuum, high-performance cooling systems, or low-pressure carbureted fuel systems on your aftermarket ECU or digital dash display.

Engineered with a solid-state internal sensor design and an all-stainless steel body, this 30 PSI transducer delivers fast, real-time voltage signals directly to your engine management hardware—keeping your project moving forward without blowing out your wallet.

???? Important Compatibility & Replacement Note

A Smart, Budget-Friendly Alternative to Honeywell & Haltech: If you are currently replacing a genuine Haltech 30 PSI or Honeywell 30 PSI pressure transducer, this unit serves as a direct software replacement.

Because it shares the exact same industry-standard 0.5V to 4.5V linear calibration scale (where 0.5V = 0 PSI and 4.5V = 30 PSI), you do NOT need to change your existing ECU software calibration mapping. Your existing Haltech or Link ECU software settings will read this sensor perfectly.

Note: While internal linear scaling matches perfectly, the external plastic alignment ridges (the "keying") on the factory plug loom can vary slightly between manufacturers. If your existing engine loom plug doesn't smoothly click into place, simply snip the old plug off and crimp on the included matching 3-pin connector kit. This is an absolute lifesaver if you are on a tight budget, running low on project funds, or building a backup track-day spares kit!

Wiring & ECU Pinout Guide

To ensure a seamless installation, match up the molded letters on the back of the included plastic plug housing to your ECU wiring harness:

  • Pin A: Sensor Ground (Connect to ECU Signal Ground / Blue-Black)
  • Pin B: +5V Reference Power (Connect to ECU 5V Sensor Supply / Orange)
  • Pin C: Sensor Signal Output (Connect to an available ECU Analog Voltage Input)
