Instead of a timing mark alignment, you'll need to check the camshaft position sensor and crankshaft position sensor signals are correctly read by the PCM (Powertrain Control Module). This is best done with a scan tool capable of reading those sensor signals and confirming proper timing operation. Trying to adjust timing "marks" directly is impossible and will likely damage the engine.
If you're experiencing timing-related issues, such as a misfire or poor running, focus your attention on:
* Crankshaft Position Sensor (CKP): Ensure it's properly seated and not damaged.
* Camshaft Position Sensor (CMP): Check for proper seating and damage.
* PCM: A faulty PCM could also cause timing-related problems.
* Wiring and connectors: Inspect for corrosion, breaks, or loose connections in the wiring harness leading to the sensors and PCM.
In short: Don't look for timing marks to align. A scan tool is the necessary diagnostic tool for this engine's timing system.
