What if a simple fault code could end up costing you thousands of euros?The P170B code—often overlooked on DAF trucks—can hide far more than just a minor electronic glitch. This fault, linked to the automated transmission management system, may be a warning sign of a major failure if not addressed promptly. So, what does this […]
Modern direct injection (GDI) and turbo petrol engines require precise control of the air/fuel ratio (AFR). To achieve this, manufacturers use wideband (UEGO) lambda sensors, which allow much finer regulation than a conventional narrowband lambda sensor. A faulty wideband sensor can cause: Thanks to HaynesPro, technicians have access to manufacturer data, normal value ranges, and […]
