Why is there oil in my mass air flow sensor?
Oil gets trapped, sucked into the air intake tube, and from there it coats everything between the intake tube and the pistons. You probably have a clogged breather tube, oil built up in the intercooler, a sticking throttle body, oil fouled spark plugs, and possibly another ruined MAF sensor.
How much does it cost to clean a SLK MAF sensor?
For around $8.00, SLK owners will likely want to attempt to clean a problematic MAF sensor before buying a replacement. The cleaner instructions recommends spraying 12-15 squirts inside the sensor, being careful to not contact the probe with the cleaner’s straw.
How to clean Mercedes Benz mass air flow sensor?
The cleaner instructions recommends spraying 12-15 squirts inside the sensor, being careful to not contact the probe with the cleaner’s straw. Also squirt the plug contacts and the mesh screen. After cleaning, no visible oil or contaminants remain on the probe, screen, or housing’s inner wall. The cleaner evaporates in a few minutes.
What happens if the MAF sensor is not working?
If the MAF sensor isn’t functioning properly, the car’s ECU (Engine Control Unit) can over-fuel the engine. When the engine runs rich (disproportionate amount of fuel to air), the exhaust gas temperature rises. In extreme cases, hot exhaust can cause the catalytic converter’s internal honeycomb material to unbond from the converter’s housing.
Where is the MAP sensor on a 1999 SLK 230?
Can anyone tell me where the MAP sensor is located on a 1999 SLK 230? I’m stumped. the SLK230 pre 2000 doesnt use a MAP sensor, only MAF to do its primary air measurement.

Does oiled air filter damage MAF?
Yes it can! An oil element air filter is the leading cause of death for a MAF sensor. If properly oiled you are absolutely correct, there will be no issues.
How do I know if my MAF sensor needs to be cleaned?
3 Signs of a Bad Mass Air Flow Sensor
- Stalling, jerking, or hesitation during acceleration.
- air fuel ratio is too rich.
- air fuel ratio is too lean.
Does oiled air filter damage engine?
Oiled filters will damage your engine’s MAF sensor. Dry filters are the only way to go. Dry filters let tons of dirt get through to damage your engine’s pistons and rings.
Are oil air filters bad for your car?
Oiled filters must be regularly cleaned, maintained and properly oiled, or else they can become detrimental to performance. You may have also heard that oiled filters can damage your mass airflow sensor (MAF). There are benefits to both types of air filters.
What causes a MAF sensor to go bad?
The MAF (Mass Air Flow) Sensor is dirty or faulty (if equipped). Note: The use of “oiled” air filters can cause the MAF to become contaminated if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
How much does it cost to replace a MAF sensor?
MAF Sensor Replacement Cost. A Mass Air Flow Sensor is not so cheap but it is not very expensive either. You could get one for $120 – $300 to which you should add labor costs of $80 – $100. Therefore, on average you are expected to pay $200 to $400 in total for a mass air flow sensor replacement.
What can I use to clean a mass air flow sensor?
The second technique is to buy a mass air flow sensor cleaner spray from a nearby auto store and use it to clean the sensor. One recommended cleaner is the CRC 05110 Mass Air Flow Sensor Cleaner – 11 Wt Oz. which can be found on the link on Amazon. It is specially designed to clean MAF sensor wires.
What does trouble code p0100 mean on MAF sensor?
The mechanic will use a scan tool to check what trouble code is retrieved. The trouble codes from P0100 to P0104 all indicate that something is wrong with the mass air flow sensor. The trouble code P0171 and P0174 are also caused due to a damaged or faulty mass air flow sensor.
