2009 Toyota Blade MAP sensor — relevance, purpose and servicing

Based on Toyota technical literature, a MAP sensor is relevant and fitted to the 2009 Toyota Blade. Both AZE156 (2AZ‑FE 2.4 petrol) and GRE156 (2GR‑FE 3.5 V6 “Blade Master”) variants include a manifold absolute pressure sensor feeding the ECM. This is documented in Toyota Repair Manuals for Auris/Blade (RM series for AZE/GRE156), Toyota Electrical Wiring Diagrams showing the MAP signal to the ECM, and the Toyota Electronic Parts Catalogue listing a MAP sensor for these frames. The factory diagnostic sections also reference MAP‑related DTCs P0106, P0107 and P0108 for these engines, confirming its use.

For owners and workshops, the MAP sensor on a 2009 Toyota Blade is a quiet achiever. It reads the absolute pressure in the intake manifold so the engine computer can figure out air density and load. On the Blade, it works alongside the MAF sensor to keep fuelling tidy across Aussie and Kiwi conditions, from sea‑level commutes to hilly weekend drives. When the MAP data is on the money, throttle response feels crisp, fuel economy stays consistent, and emissions gear like EVAP and VVT‑i strategies behave as intended.

There’s no fixed replacement interval for the MAP sensor, it’s usually a fit‑and‑forget item. That said, it can be affected by oil mist, dust that slipped past an old filter, or silicone spray residue. As part of scheduled servicing, it’s smart to check that the sensor’s connector is snug, the O‑ring isn’t perished, and the short vacuum passage and manifold port aren’t gummed up. If cleaning is needed, use an electronics‑safe cleaner and avoid poking the sensing port. Let it dry completely before refitting.

When a Blade’s MAP sensor goes out of spec, it can cause lumpy idle, sluggish take‑off, sootier exhaust, or higher fuel use. The dash may light up with a CEL, and scan tools commonly show P0106–P0108. Before throwing parts at it, rule out splits in the intake duct, loose clamps, or manifold gasket leaks—vacuum leaks can mimic a bad MAP reading.

• Service tips: inspect at major services (e.g., 60,000–100,000 km), keep the air filter fresh, and avoid oiling near the intake.
• Replacement advice: choose a quality part with the correct Toyota connector and O‑ring, clear codes after installation, and verify live data (kPa tracks baro KOEO, drops at idle) on a scan tool.

A well‑kept MAP sensor helps the 2009 Blade run sweet as, delivering smooth drivability and tidy fuel economy across New Zealand and Australian roads.

Popular questions about 2009 Toyota Blade MAP sensor

Where is the MAP sensor located on a 2009 Toyota Blade?

On most 2AZ‑FE Blades it sits on the intake manifold near the throttle body, held by a small screw with a single three‑pin connector. On the 2GR‑FE V6, it’s mounted on the upper intake plenum, lift the engine cover and look toward the rear bank side of the manifold. It has an O‑ring seal and points into the manifold port.

What fault codes point to a MAP sensor issue on a 2009 Blade?

Common codes are P0106 (range/performance), P0107 (low input), and P0108 (high input). You might also see mixture codes if the reading is skewed. Always check for vacuum leaks, a dirty throttle body, or wiring issues, as these can trigger MAP codes even when the sensor itself is fine.

Should the MAP sensor be cleaned or replaced?

There’s no routine replacement interval. If contamination is suspected, a light clean with electronics‑safe cleaner is fine—don’t soak it or touch the sensing port. If readings stay erratic or codes return, replace it with a quality unit. After refitting, clear codes and confirm live data under the bonnet with a scan tool.
