About this problem
A check engine light with loss of power means the engine computer has found a fault serious enough to cut performance. On small turbocharged engines, common causes include coolant and turbo problems, cracked or leaking hoses, sensor faults and misfires. The light alone does not say what is wrong, but a free code scan at a parts store can point to the system involved.
