What causes the engine shaking and fault light to come on?
1 Answers
Engine shaking with the fault light illuminated can be caused by the following reasons: 1. Oxygen sensor malfunction - The oxygen sensor provides feedback to the engine about the air-fuel mixture. If it fails, it may lead to inaccurate fuel injection quantities, causing engine shaking. 2. Clogged catalytic converter - The catalytic converter is responsible for purifying exhaust gases. A clogged converter not only causes engine shaking but also results in noticeable power loss. Solution for engine shaking with fault light on: It is recommended to visit a repair shop to read the specific fault codes using diagnostic equipment, accurately identify the fault point, and have it repaired by professionals.
