2013 Toyota Wish MAP sensor – what it does and why it matters

Technical sources confirm the 2013 Toyota Wish (ZGE2# series with 1.8L 2ZR-FAE and 2.0L 3ZR-FAE engines) is fitted with a Manifold Absolute Pressure (MAP) sensor. Toyota’s service manuals for the 2ZR/3ZR engine control system list the MAP sensor as a monitored component, and Toyota’s diagnostic trouble codes P0105–P0108 are defined for these engines, which only trigger when a MAP sensor is present. Toyota’s electronic parts catalogues for the Wish also include a “vacuum sensor (manifold absolute pressure)” mounted on the intake manifold. These are standard references used by workshops across Australia and New Zealand.

The MAP sensor on a 2013 Wish keeps the engine computer in the loop about what’s happening inside the intake manifold. By reading manifold pressure, the ECU works out engine load and fine‑tunes fuel delivery and ignition timing. Even though these ZR engines also use a MAF sensor, the MAP backs it up for fast throttle changes, altitude compensation, EGR checks, and on-board diagnostics. When it’s healthy, cold starts are clean, throttle response is crisp, and fuel economy stays on target.

As part of regular servicing, a quick MAP sensor check is a smart move. They don’t have a strict replacement interval, but oil mist and carbon can build up in the port over time. If the Wish shows rough idle, doughy acceleration, higher fuel use, black smoke, or throws codes like P0106/P0107/P0108, the MAP is worth a look.

• Location: bolted to the intake manifold, near the throttle body, with a small vacuum port into the plenum.
• Inspection: with the bonnet up and engine off, unplug the connector, check for cracked wiring or a perished O‑ring, and make sure the sensing port isn’t clogged.
• Cleaning: use electronics- or MAF-safe cleaner only, a gentle burst into the port is plenty. Don’t poke the sensing element.
• Replacement: ignition off, one retaining screw out, swap the sensor and O‑ring, refit, then clear codes and perform a short idle learn drive (let it idle, then a relaxed run through the revs).

Genuine or quality OE-equivalent sensors tend to give the best long-term results. A quick scan-tool check of live data (key on, engine off ≈ local barometric pressure, engine idling ≈ 25–40 kPa on a warm engine) helps confirm it’s reading sensibly. Look after it, and the Wish will keep pulling smoothly and sipping fuel the way it should.

Popular questions

Where is the MAP sensor on a 2013 Toyota Wish?
The MAP sensor sits on the intake manifold, usually near the throttle body. It’s a small, rectangular sensor with a two- or three-pin plug and a single bolt, sealing to the manifold with an O‑ring. Under the bonnet, follow the air intake to the throttle, the sensor is just downstream on the manifold plenum.

What are the symptoms of a failing MAP sensor on a Wish?
Common signs include rough idle, flat spots, poor fuel economy, hard starting, or a check engine light with codes like P0106–P0108. Because the ECU relies on accurate load data, a lazy or contaminated MAP can make the engine run rich or lean, especially during quick throttle changes or at cruise.

Can a 2013 Wish run with the MAP sensor unplugged?
It may start and limp using backup values, but it won’t run well and the check engine light will stay on. Fuel economy and drivability will suffer. It’s best to diagnose properly, clean or replace the sensor as needed, and clear any stored codes so the ECU can relearn correctly.
