2007 Subaru Tribeca MAP sensor — what it does, and how to look after it

Yes, the 2007 Subaru Tribeca is fitted with a MAP (Manifold Absolute Pressure) sensor. This isn’t guesswork — the Subaru Factory Service Manual for the 2007 Tribeca (Engine Control/Diagnostics) documents the MAP sensor and related fault codes P0106–P0108, and Subaru’s parts catalogue lists a MAP sensor for this model (commonly referenced as Subaru p/n 22627AA350, application varies by VIN). Major OE catalogues from Denso/Hitachi also list a dedicated MAP sensor for the 2006–2007 Tribeca. So, it’s relevant, it’s used, and it’s important.

On the Tribeca’s EZ30 H6, the MAP sensor reads pressure in the intake manifold and reports engine load to the ECU. That data is blended with inputs like the MAF reading and throttle angle to fine‑tune fuelling and ignition timing, keep idle steady, adjust for altitude, and validate EGR/EVAP operation. When the MAP signal goes off, you’ll often feel it: rough idle, lazy acceleration, higher fuel use, and the odd stall. The ECU will usually light the MIL and may log codes such as P0106 (Range/Performance), P0107 (Low Input), or P0108 (High Input).

It’s not a scheduled service item, but a quick check during routine servicing is smart. A technician will:

• Inspect the MAP sensor port and O‑ring for oil mist or carbon build‑up.
• Check the connector for green corrosion and the harness for rub‑throughs.
• Verify the vacuum source/manifold port isn’t blocked.

Light contamination can often be cleaned. Use electronics-safe cleaner (not aggressive solvent) and avoid poking anything into the sensor port. Let it dry fully before refitting. If the diaphragm or electronics are failing, replacement is straightforward: under the bonnet, locate the MAP on the intake manifold near the throttle body, unplug the connector, remove the retaining screw, swap the O‑ring, and refit. Tighten to the factory spec in the service manual, reconnect, clear codes, and road test. Some shops will perform an idle relearn — let it idle with accessories off, then a short drive cycle — to stabilise trims.

When replacing, match the part by VIN to ensure the correct calibration. Genuine or reputable OE-equivalent sensors tend to give the most consistent results on Subarus. If drivability issues persist after replacement, check for vacuum leaks and confirm the MAF and throttle body are clean, as those can mimic MAP faults.

Popular questions

Where is the MAP sensor on a 2007 Subaru Tribeca?
It’s mounted on the intake manifold, typically near the throttle body. You’ll see a small, rectangular sensor with a single electrical connector and a sealing O‑ring to the manifold.

Can the MAP sensor be cleaned or should it be replaced?
If it’s just light oil mist or soot, a careful clean with electronics-safe cleaner often restores a good signal. If there’s internal failure (codes return quickly, or readings are erratic), replacement is the reliable fix.

What fault codes point to a bad MAP sensor on a Tribeca?
Common MAP-related codes are P0106 (range/performance), P0107 (circuit low), and P0108 (circuit high). Always confirm wiring integrity and vacuum leaks before condemning the sensor.
