Ignition Timing Advance -- Degrees of ignition timing (spark) advance Many modern vehicles have VVT (variable valve timing), which adjusts the camshaft position and, in turn, alters the timing of the valves. Diagnostic trouble code (DTC) P0021 is defined as “‘A’ Camshaft Position – Timing Over-Advanced (Bank 2). The best time to fire the spark plugs can vary quite a bit based on engine load, engine speed, and assorted other conditions. Is that normal? On these vehicles with variable valve timing, the PCM will adjust the timing on the situation it is called for. Monitoring spark timing ensures Engine lifetime, power, and fuel economy are all affected by ignition timing. Issue with the VVT can set a P0022 Code. Only timing advance cyl#1 will show up in live data. What causes it, symptoms to look out for, and how to fix it yourself. Learn what steps to follow to diagnose and repair this problem.
