Parts for your 2013 Suzuki Splash-Map sensor

2013 Suzuki Splash MAP sensor: what it does and how to look after it

Based on technical sources — the Suzuki Workshop Manual (Splash 2008–2014, Engine Control System), the Suzuki Electronic Parts Catalogue for MY2013, and trade databases like Autodata and HaynesPro — the 2013 Suzuki Splash is fitted with a Manifold Absolute Pressure (MAP) sensor on the K10B 1.0 and K12B 1.2 petrol engines, and a boost/MAP sensor on the 1.3 DDiS diesel. So yes, a MAP sensor is relevant and used on this model.

On the Splash, the MAP sensor feeds the ECU real-time intake manifold pressure so it can figure out engine load. Paired with intake air temp and throttle position, it lets the ECU nail fuel delivery and ignition timing, supports idle control and decel fuel cut, and on the DDiS, manages turbo boost and EGR. It’s a simple solid-state sensor, but when it goes out of whack the car can feel doughy off the line, idle can hunt, fuel use climbs, and the MIL pops on with codes like P0106–P0108. Petrol engines may feel flat or surge, the diesel can over/under-boost.

It’s not a regular “replace by X km” item, but it’s smart to check it as part of major servicing (about every 20,000 km or annually). Keep the throttle body and PCV system tidy so oil vapour doesn’t gum up the MAP’s port. If the sensor lives on the manifold (petrol) or charge pipe/manifold (DDiS), make sure the O-ring seals properly and the connector is clean, with no green crust on the pins. If cleaning is needed, use an electronics-safe MAP/MAF cleaner only — no harsh solvents, and don’t poke the sensing element.

Replacing one is straightforward: disconnect the battery negative, release the plug, undo the fasteners, swap the O-ring, and snug the screws — they’re small, so just nip them up per workshop spec, not gorilla tight. After refitting, clear fault codes and let the ECU relearn idle with a short warm idle and a calm drive cycle. Stick with a quality OE-equivalent unit (Denso/Bosch listings appear in trade catalogues for Splash) so the voltage range (roughly 0.5–4.5 V across load) is spot on. If the Splash still plays up, smoke-test for vacuum leaks and check the PCV hoses before blaming the new sensor.

• Common clues: rough idle, sluggish accel, high fuel use, MIL with P0106–P0108, turbo boost issues (DDiS).
• Service tip: inspect wiring, seals, and hoses every service, clean only with MAP-safe spray.

Popular questions about the 2013 Suzuki Splash MAP sensor

Where is the MAP sensor on a 2013 Splash?
The petrol K10B/K12B usually has the MAP sensor mounted on or near the intake manifold, pointing into a small port. The 1.3 DDiS uses a boost/MAP sensor on the intake manifold or charge pipe. Look for a small, three-pin sensor with an O-ring seal and a single retaining screw or two.

Can it be cleaned or should it be replaced?
If it’s just oily vapour residue, a gentle clean with MAP/MAF-safe electronics cleaner can restore normal readings. If the sensor throws implausible signals, has water ingress, cracked housing, or damaged pins, replacement is the go. Always check for vacuum leaks and brittle hoses first.

What fault codes point to a bad MAP sensor?
Common codes include P0106 (range/performance), P0107 (low input), and P0108 (high input). On the diesel, you might also see boost correlation codes. Confirm with live data — at key-on/engine-off the MAP should read close to local barometric pressure.
