Causes A code P0139 may mean that one or more of the following has happened: The oxygen sensor is faulty The wiring to the sensor is broken / frayed There is an exhaust leak Possible Solutions The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is more than likely the rear driver's side oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions: Check and fix any exhaust leaks Check for wiring problems (shorted, frayed wires) Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor, replace if necessary Check for inlet air leaks Check the MAF sensor for proper operation
