On a 2007 Lexus RX350, the MAP (Manifold Absolute Pressure) sensor bracket mounts at the rear of the intake manifold, typically on the bank closest to the firewall. The bracket itself usually attaches using a small bolt or two that threads into pre-tapped holes on the intake manifold or adjacent metal support near the upper portion of the engine.
Here’s a basic walkthrough to help:
-
Locate the MAP sensor — It’s usually a small rectangular sensor with a vacuum port and a 3-wire electrical connector.
-
Bracket position — On the RX350, the MAP sensor is mounted on a small metal bracket that bolts directly onto the upper rear section of the intake manifold, often near the throttle body or EGR plumbing.
-
Mounting — The bracket will have:
-
One or two bolt holes that secure it to the manifold or adjacent bracket
-
A slot or hole where the MAP sensor clicks in or bolts on with a small xxxx
-
-
Vacuum hose — Make sure the sensor's vacuum port is connected to the correct manifold vacuum source.
-
Electrical connection — Plug in the 3-pin connector. Ensure it’s routed cleanly away from heat and moving parts.
If you're unsure about bolt locations, sometimes reaching back there is easier with the engine cover removed. In any case, this 2007 Lexus RX350 (XU30) Service & Repair Manual Software should show this bracket setup clearly in the intake or emissions section with diagrams.
For a more detailed and precise procedure, the manual's definitely worth getting here 👍🏻
