🔧 Kona - Mass Air Flow (MAF) Sensor Replacement

On your Kona, the “air measurement” sensor is sometimes a true MAF on the intake tube, and sometimes it’s a MAP sensor on the intake manifold (different part and location). I can walk you through the exact replacement once we confirm which sensor you’re looking at so you don’t buy/install the wrong part.

Difficulty Level: Beginner | Estimated Time: 0.3-1.0 hours

⚠️ Safety & Precautions

• 🔸 Turn ignition fully OFF and keep the key/fob away from the vehicle.
• 🔸 Let the engine cool so you don’t burn your hands on hot intake/turbo piping.
• 🔸 Do not touch the sensor element inside the housing; skin oil can ruin readings.
• 🔸 If you disconnect the battery, you may lose radio presets and idle may relearn.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Open the hood and locate the air box and the large intake tube that runs toward the engine.
• If your sensor has an electrical connector, press the lock tab before pulling; don’t yank the wires.
• Quick confirm (important): The MAF (if equipped) will be mounted in the intake tube/air box area. A MAP sensor is usually mounted on the intake manifold/charge pipe.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you’re on the MAF (not the MAP)

• Use a flashlight and find the sensor mounted into the intake tube or air box outlet (usually between the air filter box and the turbo inlet tube).
• If the sensor is mounted on the intake manifold or a hard charge pipe, stop—this is likely the MAP sensor (different procedure/part).

Step 2: Disconnect the electrical connector

• Use nitrile gloves and safety glasses.
• Press the connector lock tab by hand; if needed, gently assist with a flathead screwdriver.
• Pull the connector straight off.

Step 3: Remove the sensor from the intake tube/housing

• Remove the two sensor screws using a Torx T20 bit.
• If the screws have a pin in the center, use a Torx T20 security bit (specialty).
• Wiggle the sensor straight out; do not twist hard or pry on the plastic housing.
• Tip: Don’t drop the screws into the intake.

Step 4: Transfer/replace the seal and prep the new sensor

• Inspect the old O-ring / seal. Replace it if it’s flattened, torn, or hard.
• If there’s dirt/oil in the housing, spray with mass air flow sensor cleaner and let it fully air-dry.
• Do not use brake cleaner or compressed air on the sensor element.

Step 5: Install the new sensor

• Seat the sensor straight into the housing by hand, making sure the seal doesn’t pinch.
• Install and tighten the screws using a Torx T20 bit until snug (do not overtighten the plastic housing).

Step 6: Reconnect and recheck

• Reconnect the electrical connector until it clicks.
• Recheck that the intake tube and air box are fully seated; tighten any loose clamps with a flathead screwdriver or Phillips screwdriver (whichever your clamp uses).

✅ After Repair

• Start the engine and let it idle for 2–3 minutes. Idle may be slightly rough briefly while it relearns.
• If you had a check engine light, clear codes with a scan tool after confirming the repair.
• Test drive with light throttle first, then normal driving. Verify no warning lights return.

Quick question (so I give you the exact, correct procedure): Can you upload a photo of the sensor you’re trying to replace (showing where it sits—intake tube by the air box vs on the manifold/charge pipe)? Also, is your check engine light on, and if yes do you have the code (like P0101)?
