Looking for a highly accurate Manifold Absolute Pressure (MAP) or low-pressure tracking solution without the steep brand markup? This NZA 50 PSI Absolute Stainless Steel Pressure Transducer is the ultimate budget-friendly choice. Measuring from a perfect vacuum up to 35 PSI of positive pressure, it is the exact electronic equivalent of a standard 3.5 Bar MAP sensor.

This heavy-duty absolute sensor is engineered specifically for monitoring Manifold Absolute Pressure (MAP/Boost up to 35 PSI), wastegate dome pressure control circuits, crankcase pressure/vacuum, or engine valley pressure on your aftermarket ECU or digital dash display.

???? Important Compatibility & Replacement Note

A Smart, Budget-Friendly Alternative to Honeywell & Haltech: If you are currently replacing a genuine Haltech 50 PSI Absolute or Honeywell 50 PSI Absolute (3.5 Bar MAP) 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 PSIa and 4.5V = 50 PSIa), you do NOT need to change your existing ECU software calibration tables. Your existing Haltech or Link ECU software configurations will read this sensor perfectly.

Note: While internal linear scaling matches perfectly, the external plastic alignment ridges (the "keying") on factory plug looms can vary slightly between brands. 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 running low on project funds or looking for a cost-effective track backup!

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)
