Nissan Pathfinder 2001, rear wheel driver, 83K miles.
Engine Light is on for couple weeks then off for couple weeks, and so on. I brought it to AutoZone, and they checked it for me. Finally, they gave me the code P0138 and P0139. Not sure which sensor or something else can cause the problem.
I brought it to the Nissan dealer, they told me that my car is not under any recall like this, otherwise, they can charge me around $750 for parts and labor.
Anyone has any idea how to know exactly which sensor is failed.
Thank you
