The spark plugs may become fouled with carbon deposits and other chemical byproducts, especially if the vehicle hasn't been maintained on the suggested schedule.įouled plugs can't produce an adequate spark to ignite the air-fuel mixture. Replace them if necessary.Īfter checking the spark strength, if necessary check the following individual system components. They can short out the voltage going through the system, robbing the spark plugs of the necessary voltage to produce a good spark. Carbon traces are like small lines of carbon that form around these components. When doing a visual inspection of the ignition system's components, like the distributor cap, rotor, ignition coil, or coil pack, look for carbon traces, carbon buildup, and damage as well.

If you don't have the manufacturer's service manual, I strongly recommend getting an aftermarket manual for your exact model ( Haynes is a good inexpensive brand). Check the tests that follow, and consult your vehicle repair manual for the proper diagnostic for your particular model. If your spark can't bridge that gap at those settings, you may have worn out wires, a weak or failing distributor, a bad ignition coil or a bad ignition control module, depending on your particular module. Use an adjustable spark tester ( Thexton is an acceptable brand) to check the spark's health. What You Can Do: When you feel your engine sluggish, one of your first checks should be to inspect the spark's strength. If any of these components cause you are not getting a good spark, your engine will be sluggish. For example, spark plugs and spark plug wires, but the ignition coil and ignition timing should be checked as well. Several components in the system need service at regular intervals. Sluggish engine behavior can very often be traced to worn or faulty parts in the ignition system. Worn out or fouled plugs will make your engine run sluggish. Watch the video below for more information about this problem. Other problems that can trigger the REP light come from the throttle body (including wiring), oxygen sensor, accelerator pedal position (APP) sensor (or harness), low engine oil pressure, or coolant loss. The most common triggers of this warning light are the harness connecting to the throttle position sensor (TPS), or the TPS itself. This is a scary situation if the problem happens while you are driving down the highway or in heavy traffic. When this light (or both lights) comes on, you'll notice the engine barely responding to the accelerator. Many GM vehicle models come equipped with a Reduced Engine Power (REP) warning light, similar to the Check Engine Light (CEL).
#Chevy sonic engine electric holes code
On some vehicle models, a failing camshaft position (CMP) sensor can cause your engine to suddenly lose power the computer will most likely set a code if it detects a problem with this sensor. It is possible that a related fault may have the computer "think" that another circuit or component is failing. Whatever codes you find, always test the circuit or components indicated in the trouble code. A malfunctioning sensor or actuator may cause the car computer (or transmission) to receive signals with the wrong voltage, causing the computer to lean the air-fuel mixture and rob your engine (or transmission) of power. You may have a pending code that can guide you to the source of the problem.
