The Bosch Motorsport PS-AA 1 is a pressure-only absolute sensor from the PS-AA family, covering 0.1–1.15 bar — the full manifold pressure range of a naturally aspirated engine from high vacuum at closed throttle to slightly above atmospheric. Ratiometric 5 V output (0.5–4.5 V nominal) and 1 ms response time make it a direct input to any ECU MAP channel.
The PS-AA measures pressure only. If both pressure and temperature are required from the same port, use the PST-1 combined sensor (SKU 0261230333) which covers the same 0.1–1.15 bar range with a simultaneous NTC temperature output.
