Spectra MP182 Manifold Absolute Pressure Sensor

OE-Style MAP Sensor Replacement

The Spectra MP182 manifold absolute pressure sensor is built to meet or exceed OE specifications for fit, form, and function. It is a direct replacement option for a wide range of Lexus and Toyota applications that rely on accurate intake manifold pressure readings.

Compatible With Lexus GX460, LC500h, LS500h, RX450h, RX450hL, GS450h, and CT200h, plus Toyota Prius, Prius C, Prius V, Prius Plug-In, Highlander, Tundra, and Sequoia applications.

• Black plastic housing with a rectangular connector layout
• 4 blade terminals with a male connector and male terminal design
• Single-port sensor construction for manifold pressure measurement
• OE-style fit, form, and function for direct replacement use

How This Sensor Works

The MP182 monitors manifold pressure so the engine control system can calculate load and adjust fuel delivery, ignition timing, and related engine management inputs. When the original sensor becomes inaccurate or fails, drivability and efficiency can suffer. This part cross-references Delphi PS20086 and Standard Ignition AS614 for the same application.

Common Problems It Can Address

• Rough idle caused by incorrect manifold pressure readings
• Hesitation or poor throttle response during acceleration
• Check engine light conditions related to MAP sensor faults
• Fuel trim issues caused by inaccurate engine load data
• Hard starting or unstable running from sensor signal errors

Installation Notes

Verify connector shape, terminal count, and port configuration before installation. Confirm the application against the vehicle’s engine management system and inspect the intake tract for vacuum leaks or contamination that could affect sensor readings. Use the listed fitment to match the correct Lexus or Toyota application before replacement.

Quality Assurance

Spectra states that this manifold absolute pressure sensor is engineered to meet or exceed OE specifications for fit, form, and function. The MP182 is intended as a direct replacement for the listed applications and is built to align with original equipment requirements.
