Parts for your 2007 Toyota Wish-Map sensor

Is a MAP sensor used on the 2007 Toyota Wish?

For the 2007 Toyota Wish most commonly seen in Australia and New Zealand (ZNE10 series with the 1.8‑litre 1ZZ‑FE), a separate Manifold Absolute Pressure (MAP) sensor isn’t used for engine load calculation. Toyota’s own service literature for the 1ZZ‑FE SFI system (Toyota TIS and New Car Features) specifies a DENSO hot‑wire Mass Air Flow (MAF) sensor with built‑in Intake Air Temperature, and the component layout for ZNE10 in the Toyota Electronic Parts Catalogue shows no dedicated MAP sensor on the intake manifold. That means a “MAP sensor replacement” isn’t relevant for the 1.8L Wish.

There are Wish variants (like some ANE10/ANE11 2.0‑litre models with the 1AZ series) that may include a manifold pressure sensor for specific control/diagnostic functions depending on market spec, but these are far less common in local AU/NZ imports. Owners can verify by checking their VIN against Toyota EPC or by viewing the intake manifold for a small three‑pin pressure sensor body, the 1ZZ‑FE typically won’t have one.

Why doesn’t the 1.8L 2007 Wish use a MAP sensor? Toyota engineered this generation of 1ZZ‑FE to run primarily on a MAF‑based strategy. A MAF directly measures the mass of incoming air, letting the ECU fuel the engine precisely across conditions without relying on vacuum as a proxy. It’s a robust approach for emissions, economy, and drivability on these naturally aspirated engines.

• MAF measures real air mass, improving mixture control on cruise and light throttle.
• Fewer vacuum‑dependent corrections in changing weather and altitude.
• Streamlined diagnostics and stable idle quality on the 1ZZ‑FE SFI setup.

Technical references: Toyota Service Information (TIS) — SFI System description for 1ZZ‑FE, Toyota New Car Features (engine control section) for 1ZZ‑FE, Toyota Electronic Parts Catalogue (ZNE10 component layout), DENSO Engine Control overview for hot‑wire MAF systems. These sources document the MAF‑based load sensing and the absence of a listed MAP sensor on the ZNE10 1.8L Wish.

Popular questions about the 2007 Toyota Wish MAP sensor

Does a 2007 Toyota Wish 1.8 have a MAP sensor?

On the 1.8‑litre 1ZZ‑FE (ZNE10), no. It uses a DENSO hot‑wire MAF on the airbox for load calculation, and there’s no separate MAP sensor shown in Toyota’s component listings for that variant. If the vehicle is a 2.0‑litre model, it may be equipped differently depending on market.

How can someone tell if their Wish actually has a MAP sensor?

Visually inspect the intake manifold: a MAP sensor is a small three‑wire pressure sensor bolted to the manifold with a short nipple into manifold vacuum. If it isn’t present and the car has a MAF at the airbox, it’s the typical 1ZZ‑FE setup. Checking the VIN in Toyota’s EPC or TIS will also confirm the exact component list.

Rough idle or poor economy on a 2007 Wish — is that a MAP issue?

On the 1.8‑litre 1ZZ‑FE, rough idle and economy issues are more commonly tied to a dirty or failing MAF, intake leaks, or throttle body deposits. Many owners restore smooth running by cleaning the MAF with proper MAF cleaner and tidying up any split vacuum hoses, rather than chasing a MAP that isn’t fitted.
