2007 Toyota Highlander MAP sensor: purpose, care and when to replace

Yes, a MAP (Manifold Absolute Pressure) sensor is fitted to the 2007 Toyota Highlander (also known as Kluger in some markets). Toyota’s factory Repair Manual and EWD for the 2007 Highlander list a “Vacuum Sensor (MAP)” in the engine control system for both the 2.4L 2AZ‑FE and 3.3L 3MZ‑FE engines, and the official parts catalog shows a dedicated MAP sensor assembly and O‑ring. The diagnostics section also includes MAP‑related fault codes P0105–P0108, confirming the part is used on this model.

On this Highlander, the MAP sensor helps the engine ECU figure out real‑time engine load by reading absolute pressure inside the intake manifold. Paired with the MAF sensor and oxygen/air‑fuel sensors, it fine‑tunes fuel delivery and ignition timing so the SUV runs smoothly, pulls well up hills, and keeps fuel use in check across Aussie and Kiwi conditions.

As part of routine servicing, it’s worth giving the MAP sensor a quick once‑over every 40,000–60,000 km or whenever chasing a rough idle, flat spots, poor economy, or a check‑engine light. Oil mist and carbon can build up at the sensor’s port, skewing readings. A careful clean with electronics‑safe cleaner (avoid aggressive solvents) can restore accuracy. Don’t poke tools into the port—just a light spray and let it dry. If the sensor uses an O‑ring seal, replace the O‑ring if it’s hard or cracked to prevent vacuum leaks.

Replacement is straightforward under the bonnet: locate the MAP on the intake manifold (near the throttle body on the 2.4L, on the surge tank area for the 3.3L), unplug the connector, remove the mounting screws, transfer or fit a fresh O‑ring, and reinstall. Nip the screws up snug—no need to swing off the ratchet—and reconnect the plug. If the variant uses a short vacuum hose to the sensor, replace the hose if it’s soft, split or oil‑soaked. Clear any fault codes and take a short test drive to confirm trims and drivability look healthy.

Signs it’s time to act include:

• Check‑engine light with P0105–P0108
• Sluggish performance, misfire feel, or black smoke
• Higher than usual fuel use and a hunting/rough idle

Kept clean and sealed, the Highlander’s MAP sensor quietly does its job for years, helping the big Toyota feel crisp and economical with no dramas.

FAQs

Where is the MAP sensor on a 2007 Highlander?
On the 2.4L 2AZ‑FE it’s typically on top of the intake manifold near the throttle body. On the 3.3L 3MZ‑FE it’s mounted on the intake surge tank area toward the rear bank. Look for a small black sensor with a two‑bolt mount and a single electrical connector.

What fault codes or symptoms point to a bad MAP sensor?
Common codes are P0105, P0106, P0107 and P0108. Drivers may notice rough idle, hesitation, poor fuel economy or rich running. Always check for vacuum leaks and a brittle O‑ring first, as those can mimic a failed sensor.

Is it safe to drive with a faulty MAP sensor?
Short term, the vehicle will usually run, but it may be rich, gutless or both. Prolonged driving can increase fuel consumption and risk catalyst damage. Best to fix the issue promptly and clear the codes.
