Dtc P0031 Suzuki
P0031 heated oxygen sensor (ho2s) heater circuit low voltage bank 1 sensor 1. about trouble code p0031. the engine exhaust must have a specific air to fuel ration, this is signaled by the heated oxygen sensors that detect the o2 content in the vehicle’s exhaust. it is essential for this to be accurate, so the engine can run correctly. P0032 trouble code definition. p0032 is the code for ho2s heater control circuit high (bank 1 sensor 1) what the p0032 code means. p0032 sends sensor data for the engine to operate properly as the engine exhaust should have a specific air-fuel ratio of 14. 7 to 1 as detected by the heated oxygen sensors (ho2s) which defines the oxygen content of the vehicle exhaust. The p0031 fault code is about an oxygen sensor heater circuit failure located in bank 1 sensor 1. (bank 1 is at dtc p0031 suzuki exhaust manifold by the 1 cylinder head, bank 2 is on the 2nd cylinder head). on some engines, both exhaust manifolds could have one oxygen sensor on each side on bo...
