The Check Engine Light may illuminate with code P0138, P0140, P0158, and/or P0160 stored. Our technicians recommend replacing the rear oxygen sensor, and reprogramming the vehicle's powertrain control module (PCM) with upgraded software to correct this concern.

I change all four sensors.
Check engine light stays on. Had it checked at local repair shop and it's the o2 sensor. Owner/Mechanic said it's not a big deal from the point of view of driving the car but will have to deal with it in order to pass next inspection. He said it's expensive, around $600.
