- HAS HAD THIS PROBLEM AND HAD IT FIXED BUT LIGHT JUST KEEPS COMING ON P0157 O2 SENSOR B2S2 LOW VOLTAGE, CHECK READING BOTH REAR O2 SENSORS ARE RUNNING AT IDLE 2.61 AND 2.62 VOLTS, NOT LIVE CODE NEEDS TO DROP BELOW 2.41 VOLTS. AT DRIVING SPEED AT 3.2 VOLTS. PROBLEM MAY BE FROM AFTER MARKET SENSOR AND WOULD SUGGEST BOTH SENSOR WITH O.E. PARTS WIRING IS OK ALSO MAY BE PCM, BUT AT THIS TIME COMPUTER CHECK IS UNPLUG THE BACK O2 SENSORS AND IF VOLTAGE IS 4.5 COMPUTER IS CORRECT AT THIS TIME OF CHECK. DOES NOT SHOW ANY EXHAUST LEAK THAT COULD CAUSE THIS PROBLEM TOO.
