Saab cars were originally manufactured by Saab Automobile in Sweden. However. the company went bankrupt in 2012. As of now. the Sino-Swedish investment group National Electric Vehicle Sweden Owned NEVS owns the Saab brand. but it hasn't yet released any Saab-branded vehicles.
The duration the check engine light (CEL) remains on after a repair can vary. For some vehicles, the light will turn off immediately once the issue triggering it is resolved. In others, it may take several driving cycles (a cycle involves starting the car, driving, and turning it off) for the vehicle's onboard diagnostic system (OBD-II) to confirm the problem is fixed, which could mean anywhere from a few days to a week. However, if the CEL stays on beyond this period, it's possible that either the initial repair didn't fully address the problem, or there's a new issue. It's recommended to double-check the repair work or use an OBD-II scanner for further diagnosis. Always ensure the gas cap is tight, as a loose cap is a common cause for the CEL to remain on.
There could be various reasons that cause your check engine light to come on, which may include:
1. A bad oxygen sensor: This sensor measures how much unburnt oxygen is in your vehicle's exhaust system, and if it's faulty, it could cause your engine to burn more fuel than it needs.
2. A loose or missing gas cap: The gas cap prevents gasoline fumes from leaving your fuel tank and entering the atmosphere. A loose or missing cap can cause a small decrease in fuel economy.
3. A failing catalytic converter: A failing catalytic converter can decrease your vehicle's performance, reduce its fuel efficiency, or cause it to run at a higher temperature.
4. A bad mass airflow sensor: This sensor tells your car's computer to add the correct amount of fuel relative to the air you're car is breathing, a faulty one can increase emissions, decrease fuel economy and cause the car to stall.
5. Bad spark plugs or plug wires: These parts ignite the air/fuel mixture in your engine's combustion chamber. If they're not working properly, your engine will not burn fuel as efficiently and may feel jerky during acceleration.
6. A failing ignition coil: A faulty ignition coil can cause misfires, power loss, and emission issues.
7. A malfunctioning EGR (Exhaust Gas Recirculation) valve: A faulty EGR valve can cause your vehicle's engine to misfire, experience reduced power and fuel efficiency, or fail an emissions test.
It's best to have your car inspected by a professional when your check engine light comes on, as these issues can lead to serious engine damage if not addressed promptly.
