P0157
02 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
DTC P0157, sometimes indicated as P015700 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing 02 sensor circuit low voltage (bank 2 sensor 2).
The P0157 code means that the engine’s computer has detected that the oxygen sensor in the exhaust system (Bank 2 Sensor 2) is providing a reading that is lower than what is considered normal.
There are a few things that could cause this code to set, including a faulty oxygen sensor, a wiring issue, a problem with the exhaust system, or a problem with the engine’s computer.
If the code is caused by a faulty oxygen sensor, it will need to be replaced. If the code is caused by a wiring issue, the wiring should be checked and repaired as necessary. If the code is caused by a problem with the exhaust system, the exhaust system should be checked and repaired as necessary. If the code is caused by a problem with the engine’s computer, the computer should be checked and repaired as necessary.

2007 SUZUKI XL7 with 80000.0 miles
I purchased my Xl7 luxury new in 2007 with only 368+ miles. Before i had driven the vehicle for 3 months, the stability control and traction control lights came on and i was forced to take the vehicle for service. Before my vehicle warranty expired, i had to replace the gas caps numerous times resulting in the replacement of my catalytic converter. Now before my vehicle reached 100,000 miles, i am forced to replace the electrical harness (or complete computer output). Pugmire lincoln mercury is the only dealership in my area that provides repairs for my vehicle. After the harness repair, the check engine light is back on, and the codes (in less than 3 months) reveal that codes: [P2099, P0157, P2272 and P2099] resulting that there is an oil leak, an o2 sensor problem and another catalytic fuel problem again. It is time for my 100,000 mile check-up, but i cannot get past the original problems. These conditions continue and i love my vehicle. I was using my vehicle for to and from work of less than 11 miles daily. I have driven as far west as san antonio, tx and north to baltimore md and south to jacksonville fl. My abs light continues to come on and my oil light flashes to instruct me to cut off the motor and tighten my gas cap while in motion.
