Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your Jeep Wagoneer, we exceptionally advise not to drive the car and schedule Jeep service today. Below is a list of the most typical reasons your check engine light can come on:

• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Jeep Wagoneer’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is normally caused by consistently neglected maintenance, which is why Larry H. Miller Chrysler Jeep Dodge Ram Sandy offers a complimentary multi-point inspection with every Jeep service. If you have an issue with your catalytic converter and don't get it repaired, your Jeep Wagoneer will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Jeep Wagoneer is what determines how much fuel is needed to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Jeep Wagoneer is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a crucial sign of a broken mass airflow sensor.
• Your Jeep Wagoneer has a vacuum leak. Every Jeep Wagoneer has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower unhealthy emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, exceptionally if they’re exposed to intense heat or extreme cold.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more promptly and your vehicle will be less efficient when it comes to fuel economy. So what results if I don’t change your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause meaningful damage to your catalytic converter and your Jeep Wagoneer's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the exactly appropriate mixture of air and fuel that enters the cylinders in your engine. A broken O2 sensor can also cause a vehicle to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Jeep Wagoneer if it’s not installed correctly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Wagoneer to Jeep and have our team of gifted certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could support you save substantially from having to get poor work and damage caused by poor installation work corrected.
• The battery is low or dead. The battery in your Jeep Wagoneer is every essential. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of Jeep you drive, but check our current service coupons and specials.
• One of the most typical and frequent cause is that your Jeep Wagoneer gas cap is loose, broken or missing. The gas cap for your Jeep Wagoneer serves numerous purposes. It prevents unpredictable gas fumes from being released when you aren't driving, it seals the fuel system and helps control pressure within the fuel tank. What results if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more expensive. Luckily, to change a gas cap isn't pricey. If your check engine light turns on quickly after you put gas in your Jeep Wagoneer, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• New Spark Plugs or Plug Wires are needed for your Jeep Wagoneer. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will endure a evident poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.

Will the check engine light reset itself?

The check engine light on your Jeep Wagoneer will ordinarily shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will expeditiously turn itself off. Likewise, if your catalytic converter is working accurately, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Jeep Wagoneer light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Larry H. Miller Chrysler Jeep Dodge Ram Sandy so the light and code can be double-checked and reset.
