Fault codes P0100–P0199
P01xx codes mainly cover: sensors, oxygen (lambda) sensors, fuel and air. Our list has 99 codes in this range. 1 of them mean you shouldn't keep driving. Repairs cost roughly €30–800, depending on the fault. The most common are P0100, P0101, P0102. Based on AI combined with our hands-on workshop experience and knowledge.
