Parts for your 2006 Toyota Blade-Map sensor

Is a MAP sensor used on the 2006 Toyota Blade?

Short answer: no, a MAP (manifold absolute pressure) sensor isn’t fitted to the 2006 Toyota Blade 2.4 (2AZ‑FE). This isn’t guesswork—Toyota’s own technical literature backs it. The Toyota service manual (TIS) for the 2AZ‑FE SFI system lists the airflow meter (MAF with built‑in IAT), throttle position (via ETCS‑i), crank and cam sensors, A/F and O2 sensors, coolant temp, knock sensor and EVAP pressure sensor, but no manifold pressure sensor. The Toyota Electronic Parts Catalogue for the Blade AZE15# series likewise shows no “Sensor, Manifold Absolute Pressure (89421‑xxxxx)” for the 2AZ‑FE Blade, while it does list the airflow meter (22204‑xxxxx). DENSO aftermarket catalogues mirror this—there’s a MAF option for the Blade 2.4, but no standalone MAP listing for that engine.

Why doesn’t it use one? The 2AZ‑FE in the Blade calculates engine load primarily with a hot‑wire MAF sensor, not speed‑density. On a naturally aspirated, port‑injected setup like this, Toyota’s strategy relies on the MAF and throttle data to nail fuelling and ignition, with barometric pressure handled inside the ECU and corrections coming from the wideband A/F sensor. There’s also an EVAP system pressure sensor, but that measures tank/canister pressure for leak checks—completely different job to a MAP and not mounted on the inlet manifold.

It’s worth noting the Blade Master (launched later with the 2GR‑FE V6) can be configured differently in some markets. But for the 2006 Blade 2.4 many Kiwis and Aussies see, a MAP sensor just isn’t part of the recipe.

Thinking there’s a MAP because the scan tool flashed P0106 or similar? On this model that’s often a generic code mapping quirk. More commonly, rough running or poor economy on a 2AZ‑FE Blade comes back to a dirty or failing MAF, intake leaks after the airbox, tired spark plugs, or an A/F sensor that’s gone lazy. Under the bonnet, the MAF sits on the airbox/intake tube—keep it clean with proper MAF cleaner, not brake or carb spray. If someone’s hunting for a “MAP” on the manifold, they’ll be there a while.

• Primary load sensor: MAF (with IAT) on the intake duct
• No manifold pressure sensor on the 2AZ‑FE Blade
• Don’t confuse the EVAP pressure sensor with a MAP

• Does the 2006 Toyota Blade have a MAP sensor?
  It doesn’t on the 2.4‑litre 2AZ‑FE. Toyota uses a MAF‑based control strategy and there’s no manifold pressure sensor listed in the repair manual or parts catalogue for that engine in the Blade.
• What part gets mistaken for a MAP sensor on a Blade?
  Usually the EVAP pressure sensor (for the fuel tank/canister) or the MAF on the airbox. Neither is a MAP. The EVAP sensor won’t be on the manifold, and the MAF sits upstream in the intake.
• My scan tool shows a MAP‑related code—what should I check?
  First confirm the engine: if it’s the 2.4 2AZ‑FE, focus on the MAF, intake leaks, and wiring. Some generic tools label airflow faults as MAP codes. Clean the MAF correctly and inspect the intake tube and connectors.
