Several days ago my 97 4runner showed a trouble code P0136, scheduled appointment to replace but mechanic when double checking today found additional code P1136. Is this common? Is it a sign of significant problems or is one trouble creating a 2nd? Cancelled appointment while researching but need to have fixed soon.
Many Thanks

P0136 - Heated Oxygen Sensor Circuit ( sensor # 2)

When one sensor has a problem, it can create another or the other sensor can fail too as lifespans are similar and both are on the same bank. Clear the test whichever comes fisrt and have it rectified first. Retest to see if problem comes back.
