Hold a drop light over the area and locate the sensor. The pump may leak from the weep reservoir or from the water pump shaft seal, leading to a drip of coolant onto the engine or onto the ground.

Good luck diagnosing your Sonic’s reduced engine power light. This leads to jerky shifts, unstable acceleration, and horrible gas mileage. When the engine power has been reduced, the engine and transmission can operate in totally different ways. Not being able to go 40MPH (which is almost always the case) is a safety risk. It is not meant to sustain long periods of vehicular operation. The idea behind the reduced engine power condition is to allow you to limp your Sonic into the shop or back home. Should You Drive Your Sonic with the Reduced Power Light It is responsible for taking the data from all of the sensors above, and combining it with the data from many other sensors to control the engine. The TPS data also helps determine when the transmission will shift.Īnother common cause of a reduced power condition is, if the ECU goes bad it can trigger the reduced engine power condition. If it’s not responding, the ECU has no way of telling how much gas gas you’ve given it. The throttle position sensor is one of the most vital sensors in your Sonic. If they totally go bad they usually don’t trigger the reduced engine power mode, but if you plug your code scanner and it comes up with an oxygen sensor related code such as P0160, it’s definitely worth taking a look at them.

Your Sonic’s oxygen sensors measure the amount of oxygen in the exhaust to help insure that the proper air/fuel mixture is realized. If the ECU isn’t getting the proper voltage response from the throttle body, it can’t be sure of how much it’ll really accelerate your Sonic from the gas pedal input.Īt this point, it turns on the reduced engine power mode in order to keep the vehicle from running away from you. This is one of the most common reasons the reduced engine power light comes on. Here are some of the most typical problems that can make your Sonic’s reduced engine power warning come on: A good code scanner is really cheap and can make the process a whole lot smoother. This is great news, since it helps narrow down where the ECU thinks that the problem is. If you have the reduced engine power light, then there are going to be some diagnostic trouble codes stored in your OBD II system. Without enough data, the ECU will just give you enough power to not leave you totally stranded, and may run the engine in an entirely different way. It’s effectively “in the dark” without enough vital telemetry to control the engine properly. If your Sonic has gotten this reduced engine power warning, it means that one of its engine management sensors or the ECU have gone bad. Most of the time, reduced engine power doesn’t make commuting home possible since the max speed your Chevy Sonic will reach is not going to be enough to keep you safe on the highway.

One of the most annoying things that can happen when we are driving our vehicles is when we get the reduced engine power light.
