What Does Engine Power Is Reduced Mean?

We all know that driving in the winter can be a little bit more challenging than it is in the summer. It’s slipperier, there are fewer daylight hours, and sometimes you just don’t want to deal with leaving the house. But what if your car starts giving you “engine power reduced” warnings? Well, this warning light typically means that your vehicle’s performance has been reduced to avoid damaging its engine. The ECU detected a system failure and triggered Reduced Power Mode so you’re not getting as much horsepower out of your engine while still maintaining optimal fuel efficiency.

The ECU has the capability to detect any problems and can also self-monitor its own performance while you’re driving. The Reduced Power Mode is triggered when your car needs more than what it’s capable of providing, so you’ll notice that your acceleration will be slower since power is reduced. You might also notice that with less engine power there won’t be as much heat generated in the cabin from the defroster or heater. This can make winter driving a bit easier because those things are not operating at full capacity if they’re working at all!

Some potential causes for this warning light coming on include an underlying problem with the ignition system or fuel injector control module (which controls how much air enters), low engine oil, dirty air filter, and other possible causes.

This warning light is a sign that your engine needs help so you need to take it in for service to have the problem diagnosed by an expert. Your vehicle will perform better with a proper tune-up or if any of those problems are addressed!
