Replacing the MAF sensor is a common first step for a P0102 trouble code (Mass Air Flow sensor circuit malfunction), but it doesn't always fix the issue. Here are some possibilities to explore: Double-check the Air Filter: A clogged air filter can restrict airflow and lead to a false MAF sensor reading. Ensure your air filter is clean and replace it if necessary. Verify MAF Sensor Installation: Make sure the MAF sensor is securely seated and the connections are tight. A loose connection or improper installation can cause the code. Consider Faulty New Sensor: It's unlikely, but there's a chance the new MAF sensor itself is defective. If the above steps don't resolve the issue, consult your repair manual or a mechanic for further diagnosis. Check for Vacuum Leaks: Unmetered air entering the engine through leaks can mess up the MAF sensor readings. Look for cracks, loose hoses, or disconnected components in the intake system. Other Potential Causes: Depending on your vehicle, there could be other culprits like a faulty MAP (Manifold Absolute Pressure) sensor, wiring issues, or problems with the Engine Control Unit (ECU).

@weeklytools thanks. I'm gon try cleaning the air filter holder and replace the filter. A lot of dust in it. Heard that can cause the issue too but when I have MAF unplugged, the car doesn't stall?

did you check the maf sensor wiring i have the same issue will check wires later today and will update you

@officialbarren Lost my multimeter to check so I couldn't. Had no money to get a new one and using paycheck at mechanic as I just gave up. It starts up with the maf unplugged (well it did) now being a whole as$ bith.

@JasonJASniper damn. ill update you with my situation in a couple hours maybe we have the same issue

You're right, a P0174 trouble code indicates low oil pressure in your vehicle. This is a serious issue that can damage your engine if not addressed promptly. Here's a breakdown of what P0174 means and what you can do: Understanding P0174: P0174 is a generic OBD-II code, meaning it's used by most car manufacturers to signal low oil pressure. Engine oil acts like a lubricant, reducing friction and wear between engine parts. Adequate oil pressure ensures proper oil circulation throughout the engine. Low oil pressure means engine parts aren't getting enough lubrication, which can lead to overheating, increased friction, and ultimately, engine damage. Possible Causes of P0174: Low Oil Level: The most common reason is simply not having enough oil in your crankcase. Check your owner's manual for the proper oil type and level for your car. Oil Filter Clogged: A dirty oil filter can restrict oil flow and cause low pressure. Regular oil changes are crucial. Worn Oil Pump: The oil pump is responsible for pressurizing the oil system. A worn pump may not be able to generate enough pressure. Internal Engine Leak: Leaks within the engine can divert oil and reduce pressure. This is a more serious issue. What to Do: Check Oil Level: Turn off the engine on level ground and wait a few minutes. Then, check your oil dipstick following your owner's manual instructions. If the oil level is low, add the recommended oil type and amount. Do not overfill! Don't Ignore the Warning: If the oil level is good and the warning light stays on, don't ignore it. Driving with low oil pressure can cause significant engine damage. Consult a Mechanic: It's advisable to have a certified mechanic diagnose the cause of the low oil pressure. They can check the oil pressure with a gauge, inspect for leaks, and recommend repairs. Here are some additional tips: Refer to your owner's manual for specific recommendations on oil type, oil capacity, and oil change intervals for your vehicle. Be mindful of your oil pressure warning light. If it comes on, address the issue promptly. Regular oil changes and proper oil maintenance are essential for preventing low oil pressure and protecting your engine.
