Detailed Description

The Hitachi PRS0001 manifold absolute pressure sensor is engineered to deliver the accurate pressure data your vehicle’s ECU relies on for fuel and air management. By providing a stable signal from the intake manifold, this sensor supports correct engine calculations across a range of 1997-2002 Infiniti and Nissan models. If you are replacing a failing MAP sensor on a Nissan Maxima, Infiniti QX4, or Nissan Pathfinder, PRS0001 offers the OE-style configuration needed for a direct service replacement.

This part cross-references Nissan OE numbers 22365-9E010 and 22365-9E02A for the same application.

What It Helps Fix

• Rough idle caused by inaccurate manifold pressure readings
• Hard starting related to incorrect ECU load input
• Hesitation or poor throttle response during acceleration
• Check engine light conditions tied to MAP sensor faults
• Fuel mixture issues from inconsistent intake pressure data
