Hello, I have a 2016 Opel Karl with 110,000 km and I am facing the following problem: the check engine light is on and error code 121 appears on the onboard computer. What could this code mean and how can I fix it? Thank you in advance for your help!

Error code 121 typically relates to a problem with the throttle position sensor (TPS). Start by checking the sensor's connection for any loose or corroded wires. If the connections look fine, the sensor itself might need cleaning or replacement. Let me know how it goes or if you have any further questions!
