Ошибка P0150: неисправность цепи датчика кислорода (лямбда-зонд, банк 2, датчик 1)

The oxygen sensor before the catalytic converter on bank 2 (sensor 1) is the main control sensor for the mixture. It is either a switching sensor (about 0.1 V lean to 0.9 V rich) or a wide-band sensor that works with a pump current evaluated by an interface chip. Bank 2 exists only on engines with two exhaust manifolds. P0150 is the bank 2 counterpart of P0130. Ford used it up to 2010 as the collective code for wiring faults of the bank 2 wide-band sensor reported by the interface chip and has used specific codes since 2011 (P0151, P0152, P2240/P2247/P2254). Other makers fill it as for bank 1 – an interface voltage check, a collective code or a plausibility test. No bank 2-specific manufacturer thresholds were found. If P0130 and P0150 appear together, look for a shared cause such as supply, ground or the control module. A stored code usually switches mixture control to open loop and suspends adaptation and converter monitoring.
