The check engine light on a 2006 Volvo XC70 can be triggered by various issues, such as a loose or damaged gas cap, faulty oxygen sensors, or issues with the engine's emissions system. It may also indicate problems with the engine's performance, like misfires or issues with the catalytic converter. To pinpoint the exact cause, it’s advisable to use an OBD-II scanner to read the trouble codes stored in the vehicle’s computer. Addressing these issues promptly can help prevent more significant problems down the line.
