Suzuki Forenza P0122 DTC throttle body position sensor issue related to housing seal on Suzuki Forenza

Some Suzuki Forenza owners report experiencing issues related to the P0122 diagnostic trouble code, which indicates a low input issue from the throttle position sensor 2. This problem can stem from a faulty throttle position sensor, leading to inaccurate readings due to wear and tear. Additionally, owners have noted that checking the throttle body housing seal is crucial, as a worn or damaged seal can exacerbate the P0122 DTC issue. Regular maintenance, such as keeping the engine clean, is essential to prevent throttle position sensor problems caused by dirt buildup. Furthermore, some owners recommend performing preventative measures like checking and replacing the air filter regularly, as a dirty air filter can lead to a dirty throttle body, negatively impacting sensor performance. Addressing these concerns can help effectively resolve the P0122 DTC in a Suzuki Forenza.
