🟡 Chery Tiggo 4 Pro engine fault light P0016 cam timing

Engine management light with fault code P0016 camshaft position correlation bank 1. The timing chain on the SQRE4T16D engine can stretch slightly before the recommended service interval if oil changes are delayed. This causes the camshaft timing to fall outside the acceptable range. Resetting the fault code after an oil change often clears the light temporarily. If the fault returns, the timing chain tensioner and chain must be inspected.
