The check engine light of the Dodge Caliber is meant to indicate that your compact 5-door hatchback is having a bit of an engine-related problem. And how the light illuminates can help you determine the type of problem that it is. A steady check engine light, for instance, may mean the engine may soon require a visit to the shop for a tune up. But if the light begins to blink, it signals a serious engine problem that puts your car under threat of severe damage.
A blinking engine light signals an emergency in the engine, which is often due to a severe misfire resulting with unburnt fuel reaching the exhaust system. This unburnt fuel can quickly increase the exhaust temperature and cause irreversible damage to the muffler, catalytic converter, and other exhaust components, so the engine must be shut down as soon as possible to prevent this.
Another cause of a flashing engine light is that the engine has been experiencing a problem for a significant period of time that has not been addressed quickly. The Caliber\'s onboard computer is designed to compensate when there\'s a problem, so the engine light may begin to light up without any noticeable drop in performance. However, if not fixed the problem may grow and the computer may no longer be able to keep up with it. When this happens, the steady beam of the check engine light will soon start to blink.
One of the first parts you need to look into in the Caliber once the check engine light starts to flash is the oxygen sensor. This sensor is responsible for monitoring the unburned oxygen and fuel, whose data is then used by the computer to adjust the fuel-air mixture in the cylinders to ensure an efficient burn. Over time the oxygen sensor may succumb to heat and constant exposure to oil ash, resulting in accurate readings to the computer that, in turn, may result with poor engine combustion and some of the fuel getting past to the exhaust.
While a catalytic converter may be a victim of an engine misfire, it can also be the cause to a flashing engine light. The converter works to reduce the Caliber\'s exhaust gases, and once it starts to fail the car\'s emissions worsen and the fuel mileage goes up. This, in turn, is detected by the computer and activates the check engine light.
There are a myriad of reasons of the catalytic converter failure. Aside from unburnt fuel contaminating the catalyst as mentioned earlier, exposure to engine oil and exhaust leaks can also cause the converter to seize and fail. Whatever the cause, the catalytic converter will have to be replaced.
The mass airflow sensor (MAF) is another component you should look into in the event of a blinking check engine light. This sensor tells the computer to add fuel based on the air that\'s reaching the engine. Thus, if the MAF sensor breaks down, there may not be enough or too much fuel mixed with the air.
