Problem overview

Some Mazda Protege5 owners report experiencing issues when the oil light and dashboard lights illuminate, leading to the car dying and failing to start despite replacing the fuel pump and detecting an oil leak. These problems may stem from a low oil level caused by an oil leak or burning oil in the engine. Additionally, a faulty oil pressure sensor can trigger the oil light, and a significant drop in oil pressure may cause warning lights like the oil pressure light or engine check light to illuminate. Some owners notice that the oil can icon remains on after starting, indicating a need for lubrication or low oil level, which requires checking and topping up the oil when the engine is cool. Furthermore, dashboard lights may not illuminate due to electrical issues, such as a faulty panel light control switch. It is essential for owners to address the oil leak, ensure adequate oil levels, and inspect the oil pressure sensor and electrical components to resolve these concerns. If the issues persist, consulting a professional mechanic or visiting a Mazda service station for further diagnosis is recommended.
