2015 Suzuki Splash MAP sensor: what it does and how to look after it

Technical sources confirm a MAP sensor is fitted to the 2015 Suzuki Splash. The Suzuki workshop wiring for the K10B/K12B engines identifies a Manifold Absolute Pressure sensor in the engine management system, and Suzuki’s electronic parts catalogue lists a MAP sensor for Splash petrol variants of this era, with equivalent listings in major aftermarket catalogues from Bosch and Denso. Diesel DDiS versions also use a boost/MAP sensor with an integrated intake air temperature element.

On the 2015 Splash, the MAP sensor is the ECU’s key for reading manifold pressure and working out engine load. That data drives fuel delivery, ignition timing, EGR behaviour (where fitted), and even how aggressively the auto adjusts for altitude or a hot day on the Gold Coast. When it’s healthy, cold starts are clean, throttle response is crisp, and fuel economy stays on point.

It’s not a regular “replace by kilometres” item, but it deserves attention during servicing—especially on cars that see lots of short trips, dusty roads, or the odd oil mist from a tired PCV. A quick visual once-over under the bonnet goes a long way. If the Splash is petrol, the MAP sensor typically mounts to the intake manifold with a small bolt and an O-ring, on diesel it’s in the charge-air plumbing.

• Check the connector for corrosion or loose pins, a dab of dielectric grease is handy.
• Inspect the sensing port for oil/carbon. If dirty, use sensor-safe electronics cleaner only—never poke with wire or use throttle cleaner.
• Look for vacuum leaks or perished hoses nearby, which can mimic MAP faults.
• If removing the sensor, fit a fresh O-ring if the old one’s flattened or brittle.

Common signs of a crook MAP sensor on a Splash include rough idle, flat spots, heavy fuel use, stalling when coming to a stop, sooty exhaust on diesel, and a check-engine light. Typical fault codes include P0106, P0107, and P0108. If those pop up, it’s worth confirming power, ground, and signal at the connector before condemning the sensor. Replacement is straightforward: disconnect the battery, unplug, undo the fastener, ease out the sensor, seat the new one without forcing it, reconnect, then clear codes and perform an idle relearn if the scan tool suggests it. For Splash owners across Australia and New Zealand, adding a MAP sensor check to the 10,000–15,000 km service routine is a simple way to keep the little Suzuki running sweet as.

Where is the MAP sensor on a 2015 Suzuki Splash?

On the petrol K10B/K12B, it’s mounted on the intake manifold with a single retaining screw and an O-ring seal, with a 3‑pin connector. On the diesel DDiS, it’s usually fitted in the intercooler/boost pipe and includes an intake air temp sensor. If in doubt, follow the wiring loom from the throttle body area or the boost pipe to the small pressure sensor.

What symptoms point to a failing MAP sensor on this model?

Owners often notice a rough idle, hesitant take-off, higher fuel use, or the engine light on. Scan tools commonly show codes like P0106–P0108. Because vacuum leaks and connector issues can copy the same symptoms, it’s smart to check hoses and terminals before swapping parts.

Should the MAP sensor be cleaned or replaced as part of routine servicing?

It’s not a scheduled replacement item, but a quick inspection at each service is worthwhile. If there’s oil mist or dust build-up, clean the sensor gently with electronics-safe cleaner and let it dry fully. Replace it if readings are out of spec, it’s contaminated beyond cleaning, or there’s internal damage. Always refit with a sound O-ring and clear any stored codes.
