@revzy.ai: Ever had your check engine light turn on and wondered what’s actually going wrong? 🤔 Modern engines rely on sensors to control fuel, air, timing, temperature, and engine performance. When one sensor starts failing, your car may show symptoms like poor fuel economy, rough idle, power loss, overheating, engine knocking, or even a no-start condition. Here are 6 important engine sensors to know: 1. Oxygen Sensor / O2 Sensor Helps monitor exhaust gases and fuel mixture. A bad O2 sensor can cause high fuel consumption. 2. MAP Sensor Measures manifold pressure so the engine can adjust fuel delivery. Failure can lead to power loss and poor acceleration. 3. CKP Sensor Tracks crankshaft position for ignition and fuel timing. If it fails, the engine may crank but not start or stall unexpectedly. 4. ECT Sensor Reads coolant temperature. A faulty reading can cause engine overheating or poor cold starts. 5. MAF Sensor Measures incoming air. A dirty or failing MAF sensor can cause rough idle, hesitation, or poor performance. 6. Knock Sensor Detects engine vibration or knocking. If ignored, knocking can lead to serious engine damage. Knowing these symptoms can help you troubleshoot faster before spending money on unnecessary repairs.
