How to Fix Incorrect Ignition Timing Angle?
2 Answers
There are two methods to correct incorrect ignition timing angle: the correction coefficient method and the corrected ignition timing angle method. Below is an expanded introduction: 1. Main correction items: coolant temperature correction, idle stability correction, and air-fuel ratio feedback correction. 2. Introduction to correction values: Since there are many parameters that affect engine operation, some parameters have a greater impact on engine performance, while others have relatively minor effects. However, to ensure that the engine operates with maximum power, minimal fuel consumption, and the lowest emissions of harmful gases under various conditions, it is necessary to monitor these relatively minor parameters and use them as auxiliary adjustment parameters. These parameters are referred to as correction values.
Speaking of incorrect ignition timing advance angle, I've encountered this issue several times myself. First of all, don't panic—this is usually related to sensors or the ECU. For example, a dirty or faulty crankshaft position sensor can lead to inaccurate ignition timing readings. I recommend starting by scanning for trouble codes with a diagnostic tool to check if the sensor is stuck. If that's not the issue, inspect whether the wiring connections are loose or if a fuse has blown. As for adjustment, it generally requires specialized tools to tweak the camshaft or ECU settings, but don't tamper with it yourself—you could end up making the engine worse. I once worked on a car where the owner complained about high fuel consumption, and it turned out to be an ignition timing advance angle issue that, when left unresolved, even caused cylinder wear. Preventive measures include regularly cleaning the sensors and maintaining the ignition system—it saves both money and hassle. If you're unsure, head to a repair shop and let a professional handle it. Safety first!
