Here are codes, after clearing, starting engine, turning off, and re-reading: Code: DME -> 08/F2 - Air mass flow sensor signal, short circuit to negative or open circuit Shadow-memory: 08/F2 - Air mass flow sensor signal, short circuit to negative or open circuit 5A/12 - Exhaust temperature before Oil contamination in MAF connector or O2 sensor connectors. Also check ignition coils, cam and crank sensors, and oil sensor for leakage contributing to oil intrusion in wiring harness. Defective MAF (Mass Air Flow) sensor (especially on Mercedez-Benz and other European autos. There are a lot of problems with aftermarket MAF sensors.) Delphi AF10058 Mass Air Flow Sensor. dummy. GM Genuine Parts 19330121 Mass Airflow Sensor with Intake Air Temperature Sensor. dummy. Delphi AF10057 Mass Air Flow Sensor. dummy. Mass Air Flow Sensor Meter Compatible with Chevy Silverado GMC Sierra MAF Sensor Replace 25318411 25168491 AF10043 (5 Prong) Try again! Details. If the MAF doesn't fix it, and there aren't any faults stored for cam sensors or apparent voltage supply issues, I would take a look at the VANOS adjustment unit, especially if you have high miles and/or the symptoms happen mostly when the engine is cold. Good luck! TEST 1: I notice the intake sleeve slip alittle bit on the MAF section. I readjusted the sleeve on MAF section thinking that will fix the problem. Two days later, My CEL came back again TEST 2: I unplugged the MAF and see if it turn on. It works, but the engine sound the same as before. TEST 3: The most common signs of bad mass air flow sensor (MAF) in Toyota Tundra are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. The mass air flow sensor is part of the engine’s intake system and is The most common signs of bad mass air flow sensor (MAF) in Buick Park Avenue are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe.

According to my Bentley manual (page 130-9): A faulty MAF sensor can produce the following problems: - Difficult to restart when engine is hot. - Engine starts then stalls. - Engine starts and runs only with accelerator pedal depressed, etc. A mass (air) flow sensor ( MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine . The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. Air charge sensor for E39, E46, Z3 Brand: ES#: 4475884 Mfg#: 13621432356 Qty: Availability: Back Ordered Mass Air Flow Sensor (MAF) In this video, you will learn 5 signs of a bad mass air flow sensor (MAF SENSOR). Watching this video will help you diagnose to see if it's time to replace o This MAF fits BMW E46, E39, and Z3 models. Mass Air Flow Sensor (MAF) for BMW E46, E39, and Z3 – Clickable Automotive Made in Germany by VDO and repackaged by VEMO, this Mass Air Flow sensor ensures your engine can accurately calculate the correct air/fuel ratios. The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Ford Explorer's engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Explorer's ECU. i have a few flat spots with my rev range, and i seem to be using my fuel quickly for a diesel. i had the same symptoms when i owned a Nissan S14, i changed the Air mass meter and problem solved, does anyone know where i can get a cheap but decent AMM and are they easy to change on the 320d? Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your A4 may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich. A lean condition is when there is too YKLPbmy.
