Parts for your 2013 Toyota Wish-Map sensor

2013 Toyota Wish MAP sensor – fitment, purpose and service tips

Based on Toyota service information for the ZGE2# series Wish (2ZR-FAE/3ZR-FAE), the model uses a Manifold Absolute Pressure (MAP) sensor as part of the SFI engine control system. Toyota’s repair manual (TIS) lists a MAP sensor with related diagnostics (DTCs P0106, P0107, P0108), and the Toyota Electronic Parts Catalogue identifies a manifold pressure sensor for the ZGE20/25 Wish. DENSO’s technical literature on MAP sensors also outlines their role in Toyota petrol engines of this era. So, yes — a MAP sensor is fitted and relevant on the 2013 Toyota Wish.

On this model, the MAP sensor reads the absolute pressure in the intake manifold and turns it into a voltage signal the ECU can understand. Even though the Wish also uses a MAF sensor for primary airflow measurement, the MAP sensor adds accuracy for transient throttle changes, helps with altitude (barometric) compensation, and is used by the ECU for self-diagnostics and plausibility checks. It also assists with EGR flow verification on engines so equipped. That combo means smoother drivability, better fuel economy, and more consistent starting in Aussie and Kiwi conditions, from sea-level commutes to high-country getaways.

As for servicing, there’s no fixed replacement interval — it’s an inspect-and-address item. At regular services (say every 15,000 km or annually), a quick visual under the bonnet is smart: confirm the connector is seated, the harness isn’t chafed, and the sensor mounting is secure. Because it lives on the manifold, oil mist and blow-by can leave light residue. If readings seem off in scan data or there’s a mild stumble, a careful clean with electronics-safe MAF/MAP cleaner can be worthwhile. Don’t poke the sensing port or use harsh solvents. If faults persist, replacement with an OE-quality DENSO-type sensor is the go-to rather than endless cleaning.

Tell-tales that the Wish’s MAP sensor is playing up include rough idle, flat spots, poor fuel economy, hard starts, and an illuminated MIL with codes like P0106–P0108. A quick scan is your friend: with ignition on/engine off, MAP should read close to local barometric pressure (around 100 kPa at sea level, lower at altitude). Under load it should track throttle changes smoothly. If replacement’s needed, disconnect the battery, swap the sensor, make sure the O-ring seats nicely, reconnect, clear codes, and take it for a gentle drive so the ECU can relearn trims. Sticking with genuine or OE-equivalent parts keeps the Wish happy and avoids repeat comebacks.

• Common symptoms: rough idle, high fuel use, sluggish acceleration, MIL on (P0106–P0108)
• Service tip: inspect at each major service, clean lightly if needed, replace if readings or DTCs persist
• Parts tip: choose OE/OEM-grade sensors and check connector/harness condition

Where is the MAP sensor on a 2013 Toyota Wish?

It’s typically mounted on the intake manifold near the throttle body on 2ZR-FAE and 3ZR-FAE engines, secured with small bolts and a single electrical connector. Look for a compact black sensor with a nose that points into the manifold. Some variants position it on the top or side of the manifold for easy access.

What are the signs the MAP sensor needs attention?

Expect rough idle, poor fuel economy, sluggish take-off, and an engine light with codes like P0106–P0108. Scan data that doesn’t change with throttle, or KOEO readings far from local barometric pressure, also point to a faulty sensor or wiring issue.

Can the MAP sensor be cleaned, or should it be replaced?

A gentle clean with electronics-safe MAF/MAP cleaner can help if there’s light oily residue. Avoid touching the sensing port with tools. If codes return or readings remain erratic, replacement with an OE-quality unit is the best fix. After refitting, clear codes and do a short relearn drive.
