Parts for your 2017 Suzuki Splash-Map sensor

2017 Suzuki Splash MAP sensor — relevance, purpose and service advice

Based on Suzuki technical literature and parts catalogues, a MAP (Manifold Absolute Pressure) sensor is fitted to the Suzuki Splash, including late-registered 2016–2017 vehicles using the K-series petrol engines (K12B/K10B). Technical sources that confirm this include: the Suzuki Splash/Agila B service manual Engine Control System section describing a “Manifold Absolute Pressure (MAP) Sensor” with 0.5–4.5 V output range, the Suzuki Electronic Parts Catalogue listing MAP sensor part numbers in the 18590-xxK00 family for K-series Splash variants, and equivalent Opel/Vauxhall Agila B documentation showing the same intake-manifold mounted MAP unit. So yes—the MAP sensor is relevant and used on a 2017-registered Suzuki Splash.

On the Splash, the MAP sensor’s job is to read the absolute pressure inside the intake manifold. The engine computer (ECU) pairs that pressure with intake air temperature and engine speed to figure out engine load. With that, it trims fuel, sets ignition timing, and looks after things like idle quality and evap purge. Because it reads absolute pressure, it also sorts altitude compensation on road trips up the ranges without breaking a sweat.

When a MAP sensor goes out of whack, the Splash can feel doughy off the mark, chew more fuel, idle rough, or throw the check-engine light. Common fault codes include P0106 (range/performance), P0107 (low voltage), and P0108 (high voltage). A quick live-data check on a scan tool will show kPa that don’t match reality (for example, not dropping at idle).

Location-wise, it’s typically bolted straight onto the intake manifold with a small O-ring seal and a three-pin connector. Some variants have a short stub passage, most are direct-mount with no vacuum hose to perish. Servicing is simple: inspect the connector for green crusties or loose pins, make sure the O-ring isn’t flattened, and clear any oil mist or carbon at the sensor port with electronics- or MAF-safe cleaner. Don’t poke the sensing element.

Replacement is a 10–15 minute driveway job: key off, unplug, remove the small bolts, lift out, lightly oil the new O-ring, and refit. Nip the bolts snug—no gorilla torque. After refitting, clear codes and take a short drive so the ECU can settle trims. There’s no coding required. There isn’t a set replacement interval, think of it as “as needed”, with a quick look at every major service (say, 60,000 km). Sticking with a genuine Suzuki or a reputable brand sensor helps avoid drift and weird idle behaviour that cheapies can cause.

• Typical symptoms: rough idle, flat spots, poor economy, MIL on (P0106/P0107/P0108)
• Quick care: check connector and O-ring, clean port with MAF-safe spray only
• No programming needed after replacement, perform a brief drive cycle

FAQs

Where is the MAP sensor on a 2017 Suzuki Splash?
It’s mounted on the intake manifold, near the top or rear side depending on engine orientation, with a three-pin plug and two small bolts. Look for a small black plastic sensor with an O-ring seal where it meets the manifold.

What are common symptoms or fault codes of a failing MAP sensor?
Expect rough idle, hesitation on take-off, higher fuel use, and a check-engine light. Typical DTCs are P0106, P0107, and P0108. Live-data that doesn’t drop to a sensible kPa at idle is another giveaway.

Does the Splash use a MAP or a MAF sensor?
The K-series Splash runs a MAP-based (speed-density) system rather than a hot-wire MAF. Some versions combine intake air temperature with the MAP (a T-MAP), but there’s no separate MAF on these engines.
