Fault codes P1600–P1699
Under SAE J2012, P16xx codes cover manufacturer-specific: computer and output circuits. Our list has 15 codes in this range. 1 of them mean you shouldn't keep driving. Repair prices are listed per cause, depending on make and model. The most common are P1600, P1602, P1605. Based on AI combined with our hands-on workshop experience and knowledge.
