Parts for your 2020 Suzuki Splash-Maf sensor

2020 Suzuki Splash MAF sensor — is it actually used?

Short answer: for a 2020 Suzuki Splash, a MAF sensor isn’t relevant. The Splash had wrapped up production years earlier (Europe by 2014, India by 2016), and the common petrol K‑series engines (K12/K10) used a MAP sensor-based system, not a MAF. Only the 1.3 DDiS diesel variant used a hot‑film MAF. That means if someone’s chasing a “2020 Splash MAF” for a petrol model, they’re looking for the wrong part.

Why no MAF on the petrol Splash? Suzuki engineered these small engines with a speed‑density strategy. The ECU estimates incoming air using a Manifold Absolute Pressure (MAP) sensor, intake air temperature, engine speed, and throttle position. It’s robust, tidy under the bonnet, and keeps costs down without hurting everyday drivability or fuel economy.

• Packaging and simplicity: No delicate hot‑film sensor in the intake ducting, fewer parts to get grubby or damaged during filter changes.
• Reliability: MAP sensors are less fussy about dust, oil mist and humid NZ/Aussie conditions.
• Cost and calibration: Speed‑density works a treat on these naturally aspirated K‑series engines, so there’s no real gain from a MAF.

What should owners focus on instead? For petrol Splash/Ritz models, attention should go to the MAP sensor on the intake manifold, the PCV system, vacuum hoses, throttle body cleanliness, and a good quality air filter. Typical fault codes for a struggling MAP are P0106–P0109. If a Splash is actually the diesel DDiS (1.3 Multijet), then yes, it runs a MAF in the intake snorkel and can flag codes like P0101–P0103 when airflow readings go out of whack.

One more wrinkle: “2020 Splash” listings often come from late registrations or admin carry‑overs. If in doubt, check the VIN and engine code. Petrol K12/K10? Think MAP. Diesel D13A/DDiS? That’s the one with a MAF.

• Suzuki Europe Electronic Parts Catalogue (Splash 2008–2014): K‑series petrol shows MAP sensor, D13A diesel lists an air flow meter (MAF).
• Maruti Suzuki Ritz/Splash workshop literature (K‑series petrol): Engine management uses MAP + IAT with speed‑density calculation.
• BOSCH ESI[tronic] data for 1.3 Multijet (Suzuki D13A): hot‑film MAF fitted upstream of the air filter.
• Model history guides: Splash production concluded mid‑2010s, no 2020 model year run.

Popular questions

Does a 2020 Suzuki Splash have a MAF sensor?

No for petrol models — they run a MAP sensor. Only the diesel DDiS (1.3) uses a MAF. Also, there wasn’t a true 2020 model year Splash, many listings are late-registered older cars.

Where is the “airflow” sensor on a Splash petrol, then?

There isn’t a MAF in the intake ducting. The key sensor is the MAP, bolted to or near the intake manifold. It reads manifold pressure so the ECU can calculate airflow. If the car’s hesitating, inspect the MAP, vacuum lines, throttle body and air filter.

What fault codes should owners expect for sensor issues on these cars?

Petrol Splash: MAP-related codes such as P0106–P0109 are common for pressure/voltage range problems. Diesel DDiS: MAF-related codes like P0101–P0103 point to airflow plausibility or circuit faults. Symptoms can include rough idle, flat spots and higher fuel use.
