2006 Chevrolet Cobalt U0101 Diagnostic: No Spark to Coil Pack - What Does This Mean?

Model: 2006 Chevy Cobalt Fault Code: U0101 Posted: 2017-06-26 08:30

My 2006 Chevrolet Cobalt is displaying fault code U0101, and I'm experiencing no spark from my coil pack. The vehicle has been driven normally with no recent modifications or aftermarket parts installed. I've checked the wiring and connections but still can't get a spark. What could be causing this issue? Is U0101 related to the ignition system or is it a signal problem?

Have there been any recent repairs or maintenance work done on the vehicle? The 2006 Chevrolet Cobalt has no aftermarket modifications or added devices, so we're looking at stock components. Could a faulty sensor or wiring issue be causing the U0101 code and spark failure?
