Frequently Asked Questions (FAQs)

Q1: How do I confirm if this MAF sensor fits my vehicle?
A1: Start by verifying your vehicle’s make, model, engine size and year (for example Peugeot 307 or Citroën C5 fitted with a 2.0 HDi or 2.7 HDi engine). Then match the part number on your old sensor (for example 8ET 009 142-101 or 5WK9621) with the replacement listing. Our compatibility list shows the relevant models and part numbers — if you’re unsure, use your VIN or registration and contact our team for confirmation.

Q2: What are the symptoms of a failing MAF sensor?
A2: The key symptoms include a rough or fluctuating idle, loss of power or sluggish acceleration, increased fuel consumption, black smoke (on diesel models), and illumination of the “Check Engine” or “Engine Management” warning light indicating an airflow reading fault. Since the MAF sensor directly influences fuel delivery, these faults are common indicators of its malfunction.

Q3: Can I clean the old sensor instead of replacing it?
A3: In some cases, yes — especially if the sensor is simply dirty or contaminated. Cleaning the hot-wire or hot-film element with a proper MAF-sensor cleaner can restore correct readings. However if the sensor is physically damaged, the connector is corroded, or fault codes persist after cleaning, replacement is recommended.

Q4: Is installation difficult or does the new sensor need calibration?
A4: Installation is relatively straightforward for most DIYers: disconnect the negative battery terminal first, remove the air-intake duct to access the old sensor (located between the air-filter box and intake manifold), then remove the old sensor, install the new one in the same orientation, reconnect wiring and ensure all connections are tight and sealed. After installation, it’s a good idea to clear any stored fault codes and perform a short drive to let the ECU re-learn. No special coding is typically required unless your vehicle’s system specifically demands it.

Q5: What warranty and shipping terms do you offer?
A5: This MAF sensor is shipped from UK stock and we offer free shipping on eligible orders. The unit is backed by our standard warranty covering manufacturing defects. Correct installation is required for warranty validity — we recommend keeping your receipt and following installation instructions carefully.
