Consumer Description

I KEEP GETTING A P0136 BANK 1 SENSOR 2 ERROR CODE. TOOK IT TO SEVERAL MECHANICS AND THEY SWITCHED THE 02 CENSOR (DOWNSTREAM). ALSO SHOWS THAT BANK 1 SENSOR 2 HAS 0% VOLTAGE. UNPLUGGED THE DOWNSTREAM 02 SENSOR AND GOT A READING BUT NO READING WHEN PLUGGED IN. CHECKED WIRING HARNESS TO ECM AND EVERYTHING WAS FINE. BOTH MECHANICS HAVE DETERMINED THAT THE ISSUE IS WITH THE ECM. MY VEHICLE HAS ROUGHLY ABOUT 70K MILES ON IT. MY CAR WILL NOT PASS SMOG UNTIL THIS IS FIXED. MECHANIC IS RECOMMENDING REFLASHING ECM OR REPLACING IT. P0136 COMES UP AS PENDING AND WILL STAY PERMANENT ON THE SECOND DRIVE CYCLE. CHECK ENGINE LIGHT STAYS ON.
