2013 Mazda Premacy MAP Sensor — purpose and servicing
Yes, the 2013 Mazda Premacy (Mazda5, CW series) uses a MAP sensor. This is supported by Mazda’s CW Workshop Manual (Fuel and Emission Control System), which details DTCs P0106–P0108 for the Manifold Absolute Pressure sensor, and by the Mazda electronic parts catalogue listing a MAP sensor on the intake manifold for both MZR and Skyactiv-G variants. Technical training literature for Skyactiv-G engines also notes MAP input for load calculation, EGR control and altitude compensation.
On this model, the MAP sensor reads the absolute pressure inside the intake manifold and feeds that to the PCM. That helps the car figure out engine load so it can trim fuelling, ignition timing and valve control on the fly. Even on variants that also run a MAF sensor, the MAP is crucial for transient throttle response, EGR diagnostics and as a backup strategy if the MAF goes out of whack. It also helps the start/stop system behave itself by giving a fast, accurate picture of manifold pressure changes.
Typical signs the MAP sensor needs attention include:
- Rough idle, stumble on take-off, flat spots or sluggish performance
- Higher than usual fuel use and a whiff of rich running
- Check engine light with codes like P0106, P0107 or P0108
It’s not a routine replacement item, but it should be checked during servicing. Make sure the connector is clean and the loom isn’t rubbed through, and that there’s no oil sludge or moisture sitting in the sensor port. Avoid blasting it with harsh cleaners—if there’s contamination, a light wipe of the port and a check for crankcase vapour issues is smarter.
If replacement is needed, part numbers vary by engine, common Mazda references include L3K9-18-211 for MZR applications and PE01-18-211 for Skyactiv-G. A new O-ring is a must to stop vacuum leaks. The job is straightforward:
- Switch ignition off, disconnect the negative battery terminal.
- Locate the MAP on the intake manifold (near the throttle body on MZR, firewall side on many Skyactiv-G).
- Unplug the connector, remove the retaining bolt, and pull the sensor straight out.
- Lightly oil the new O-ring, install the sensor squarely, and snug the bolt (don’t overtighten).
- Reconnect, clear codes, and verify readings: KOEO should read close to local barometric pressure, at warm idle expect roughly 25–40 kPa depending on engine and altitude.
Popular questions
Where is the MAP sensor on a 2013 Mazda Premacy?
It’s mounted on the intake manifold. On MZR 2.0/2.5 engines it’s usually on top or near the throttle body. On Skyactiv-G 2.0, look at the rear (firewall side) of the manifold. It’s a small, two- or three-wire sensor held with a single bolt.
What symptoms point to a bad MAP sensor on a Premacy?
Expect rough idle, hesitation, poor fuel economy and a check engine light. Scan tools often show P0106–P0108. Live data will show implausible manifold pressure (e.g., KOEO far from local baro, or idle kPa not dropping as expected).
Does the 2013 Premacy also have a MAF sensor, and why both?
Many variants do run both. The MAF handles steady-state airflow measurement, while the MAP sharpens response during quick throttle changes, supports EGR and altitude corrections, and provides a fallback “speed-density” strategy if the MAF signal is dodgy.
