2011 Toyota Blade MAP Sensor — What It Does, Where It Sits, and How to Look After It

Based on Toyota technical literature, the 2011 Toyota Blade does use a manifold absolute pressure (MAP) sensor. In Toyota’s Repair Manual (Engine Control/SFI System) for both the 2AZ-FE 2.4L and 2GR-FE 3.5L engines, the MAP sensor (also called the vacuum sensor, signal “PIM”) is listed with related diagnostic trouble codes P0105–P0108. The Toyota Electrical Wiring Diagram for Blade/Auris models (AZE/GRE chassis) also shows the MAP sensor feeding the ECM. That’s the long way of saying: yep, it’s fitted from factory and it matters.

On a 2011 Toyota Blade, the MAP sensor reads the absolute pressure inside the intake manifold and tells the engine computer how much air is getting in. Pairing that with the MAF and other sensors, the ECM can dial in fuel, ignition timing, and cam timing to keep it running sweet as at idle, on the motorway, and up a hill in the rain. It also helps with diagnostics and emissions by sanity-checking airflow against throttle angle and engine speed.

It typically lives on or near the intake manifold with a small O-ring seal and a three-pin connector. Over time, oil vapour and dust can gum up the sensing port, making readings lazy. The result can be rough idle, sluggish take-off, a thirsty fuel bill, or a check engine light with one of those P0105–P0108 codes.

There’s no fixed replacement interval in Toyota schedules, but it’s smart to give it attention at major services. Under the bonnet, a quick visual once-over goes a long way: make sure the connector is snug, wiring’s not chafed, and the O-ring isn’t split. If readings look off on a scan tool (key on, engine off should be close to local barometric pressure — roughly 100 kPa at sea level in Aus/NZ), consider cleaning or replacement.

• For cleaning: use an electronics-safe sensor cleaner, short bursts only, and let it dry fully. Don’t poke the port with wire or cotton buds.
• For replacement: choose quality OEM-equivalent, lightly lube the O-ring, seat it square, and avoid overtightening the screws.
• After fitment: clear codes, reset fuel trims if needed, and verify live data looks sensible on a brief road test.

Look after the MAP sensor and the Blade’s smooth manners, fuel economy, and emissions control will stay on song for many more k’s.

Does the 2011 Toyota Blade have a MAP sensor or only a MAF?

It has both. Toyota documentation for the 2AZ-FE and 2GR-FE shows a MAP sensor (vacuum sensor) feeding the ECM alongside the MAF. The MAP helps the ECM validate airflow, control fuel and spark, and support diagnostics.

If scan data shows odd manifold pressure readings or you’ve got DTCs P0105–P0108, the MAP circuit is squarely in play on this model.

Where is the MAP sensor on a 2011 Toyota Blade?

It’s typically mounted on the intake manifold with a small O-ring and a three-pin plug. On the 2AZ-FE it’s near the throttle body area, on the 2GR-FE it’s also on the manifold where it can directly sense plenum pressure.

Look for a compact black sensor with one mounting screw or clip. If in doubt, follow the loom labelled for the “PIM” signal in the wiring diagram.

Can a dodgy MAP sensor cause poor fuel economy and rough idle?

Sure can. If the MAP reports pressure incorrectly, the ECM can misjudge load, leading to rich running, flat spots, and a lumpy idle. You might also see a check engine light.

Rule out vacuum leaks and wiring first. If the sensor port is oily, a careful clean with electronics-safe spray can help, otherwise a quality replacement sorts it.
