I would say that your o2 sensors are faulty either the pre or the post . They must be intermitten so I would replace both

SOURCE: code number P0139 BK1 code number p0139 BK1

This code indicates the oxygen sensor on bank one is not operating properly. Check the wiring to this sensor for breaks or grounding before replacing the sensor.

Possible mass airflow sensor. A cheaper way to get around paying for the super expensive 2001 Path part is to use the same year maxima sensor since they use the same motor :)

P0138 - Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)

P0139 - Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)

The Heated Oxygen Sensor (1 or 2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)

Symptoms: There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.

Causes: A code P0138 may mean that one or more of the following has happened:
* Faulty O2 sensor
* Short to battery voltage in O2 sensor signal circuit
* High fuel pressure (not as likely)

Here are some potential solutions:
* Replace O2 sensor
* Repair short to battery voltage in o2 sensor signal circuit

Hope helps (remember to rate this answer).

PO-139 I had that sensor change 3 weeks ago and the check engine light came on again this morning.Thanks


Probably replaced a good sensor. This codes could be from a bad sensor, a vacuum leak, or an exhaust leak before the sensor.

What mean code p0138 on 2005 town and country


P0138 is a high voltage output on bank 1 sensor 2 (bank 1 is the same side as #1 clyinder, sensor 2 is after convertor) I would check for a rich fuel/air mixture causing the cat to overload. Need replace it.

Hope this help (remember rated this post).
