15/09/2021· Replacement of a good Oxygen Sensor (O2), is a common mistake made by (DIY) mechanics all the time. So, before replacing any of these sensors; you must first find the real problem that pushed you in that direction. The consequences of not diagnosing and checking the systems that make an engine operate properly can be costly. The Oxygen Sensor also …
29/04/2020· The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to …
