How to Test the Condition of a Cruze Ignition Coil?
2 Answers
Methods to test the condition of a Cruze ignition coil: 1. Use the substitution method for inspection—replace one ignition coil with a normal one, and if the fault disappears, it indicates a problem with the original ignition coil; 2. Measure the resistance of the primary and secondary windings with a multimeter. A high resistance reading suggests an open-circuit fault in the winding. The Cruze is a compact car produced by SAIC-GM Chevrolet, with dimensions of 4666 mm in length, 1807 mm in width, and 1460 mm in height, and a wheelbase of 2700 mm. For the interior, the Cruze features decorative panels and door trim panels in various colors, using matte materials to enhance the overall texture of the cabin.
I've driven my Cruze for many years, and the most obvious symptom of a faulty ignition coil is engine shaking, especially during low-speed acceleration, which is particularly uncomfortable. Checking whether it's good or bad isn't actually difficult. I often use a multimeter to test the resistance: first, disconnect the battery's negative terminal to ensure safety, then unplug the ignition coil connector. Use the multimeter to measure the resistance of the primary terminals—the normal range is between 0.5 and 2 ohms. If it's higher or lower, it means it's faulty. Next, test the resistance of the secondary terminals; for the Cruze, it's generally acceptable between 5,000 and 15,000 ohms. If you don't have a multimeter, observe whether the spark plug's spark is weak or absent when starting the vehicle, or use an OBD diagnostic tool to scan for trouble codes—a P030X code indicates a cylinder misfire. Remember, the average lifespan of an ignition coil is around 100,000 kilometers, and regular checks can prevent unexpected failures from affecting your driving.
