FAQs
What does a Mass Air Flow (MAF) sensor do?
A MAF sensor measures the amount of air entering the engine and sends this data to the engine control unit (ECU), which uses it to determine the optimal fuel-air mixture for efficient combustion.
Why is it important to check measurements and dimensions before buying?
Vehicle manufacturers may use different intake system designs or component sizes, even for the same model and year. Verifying measurements ensures a proper physical fit and correct connection.
What are the signs of a failing MAF sensor?
Common signs include a check engine light, rough idling, poor acceleration, decreased fuel economy, stalling, and unusual engine noises.
Can I clean a MAF sensor?
While specialized MAF sensor cleaner sprays exist, it is generally not recommended for this specific Hella part unless explicitly stated by the manufacturer. Improper cleaning can damage the sensor element.
What is the warranty on this Hella MAF sensor?
Warranty information is typically provided by the retailer or seller. Please refer to the specific product listing or contact the seller for details on warranty coverage.
How many pins does this MAF sensor have?
This Hella MAF sensor (8ET 009 142-691) has a 5-pin connector.
What is the connector diameter for the induction pipe?
The induction pipe connector diameter for this sensor is 70mm.
Troubleshooting
Check Engine Light (CEL) illuminates after installation.
Ensure the electrical connector is securely seated and the sensor is properly sealed in the intake pipe. Re-verify part compatibility with your vehicle's specifications. A diagnostic scan may be needed to clear the code if it persists.
Engine performance has not improved or has worsened.
Confirm that the correct MAF sensor model was installed and that there are no air leaks in the intake system after the MAF sensor. Ensure the sensor was not physically damaged during installation.
Difficulty fitting the sensor into the intake pipe.
Double-check the induction pipe connector diameter (must be 70mm) and compare it against your vehicle's intake pipe. Verify that no debris is obstructing the sensor or the pipe opening.

Setup, Compatibility & Care
Compatibility Verification: Before purchasing, it is imperative to verify that this MAF sensor (8ET 009 142-691) is compatible with your specific Lada NADESCHDA (2120) model, year, and engine variant. Pay close attention to the specified engine sizes (1.7, 1.7 i, 1.8) and the production years (1997-2006). Crucially, double-check the measurements and dimensions, as variations can exist even within the same vehicle model. The induction pipe connector diameter must be 70mm.
Installation: Installation typically involves locating the MAF sensor in the air intake system, usually between the air filter box and the throttle body. It will have an electrical connector and be mounted within a section of the intake pipe. Disconnect the electrical connector, unbolt the sensor, and remove it. Install the new Hella MAF sensor, ensuring a proper seal, reconnect the electrical connector, and secure any mounting hardware. It is recommended to consult a vehicle repair manual or seek professional assistance for correct installation procedures.
Care: MAF sensors are sensitive components and generally do not require routine maintenance. Avoid spraying cleaning agents directly onto the sensor element. If the air intake system is exceptionally dirty, clean it before installing the new sensor. Protect the sensor from excessive moisture and physical impact.
