2013 Mazda 3 MAP sensor — what it does and how to look after it

Based on technical sources — the Mazda 3 (BL) Workshop Manual (Engine Control System – MAP Sensor), Mazda Skyactiv-G service information, and Mazda’s OBD-II DTC list covering P0106, P0107 and P0108 — the 2013 Mazda 3 is fitted with a MAP (manifold absolute pressure) sensor across its common engines (2.0 Skyactiv-G, 2.0/2.5 MZR). So yes, a MAP sensor is relevant on this model.

On a 2013 Mazda 3, the MAP sensor measures the pressure (or vacuum) inside the intake manifold. The engine computer uses that signal to understand engine load, fine-tune fuel and ignition, run EGR and EVAP correctly, and adjust for altitude via barometric reading. Even on variants that also use a MAF sensor, the MAP is vital for quick transient response and plausibility checks. It’s typically mounted directly on the intake manifold near the throttle body, under the bonnet and easy to reach.

When the MAP sensor goes out of whack, the Mazda can feel doughy off the line, idle roughly, drink a bit more fuel, or throw a check engine light. Common codes include P0106 (MAP range/performance), P0107 (low input) and P0108 (high input). Oil mist from the PCV system or carbon can sometimes contaminate the sensing port.

As part of regular servicing of a 2013 Mazda 3, it’s smart to give the MAP sensor a quick once-over. It’s not a scheduled replacement item, but a clean sensor and a clear port help the car stay perky and efficient. If the port is dirty, remove the sensor and clean the tip and bore with electronics-safe or MAF-safe cleaner — not carb/brake cleaner — and let it dry fully. Avoid touching the sensing element. Refit the O-ring carefully and tighten the retaining fastener to the workshop manual spec (don’t overtighten). Under the bonnet checks every 10,000–15,000 km are a safe bet for local Aussie and Kiwi conditions.

• If diagnosing at home, key-on/engine-off should read about local barometric pressure (around 100 kPa at sea level).
• Look for split vacuum hoses or intake leaks that can skew readings.
• If readings are erratic or out-of-range and cleaning doesn’t help, replacement is straightforward — one plug, one bolt — and usually a 10–15 minute job.

Popular questions

Does a 2013 Mazda 3 actually have a MAP sensor?
Yes. Mazda’s BL Workshop Manual and the factory DTC list for P0106–P0108 both reference the MAP sensor on 2.0 Skyactiv-G and MZR engines. It works alongside the MAF to manage load, fuel and spark.

Where is the MAP sensor on a 2013 Mazda 3?
It’s mounted on the intake manifold, usually near the throttle body. Pop the bonnet, follow the intake snorkel to the throttle, and look for a small sensor with a single electrical connector and one retaining bolt.

Should it be cleaned or just replaced?
Start with a clean using electronics-safe spray and check the O-ring. If codes or symptoms persist, replace it with a quality part. Always clear codes and road-test to confirm the fix.
