Jeep Liberty Diesel code P0069

We have been having several problems with the jeep all related to code P0069 which is supposedly a barometric pressure correlation. Got the part from the dealer (05101120-AB Sensor) my husband replaced it and since it has been 28 days later and check engine light is back on with the same code. How does this happen? Is it really possible that I got a faulty sensor or is this a common problem with the crd jeep.

Thanks

Hi
I will need to check but I believe the barometric pressure sensor is part of the ECM (engine module) and not a part you could change.
Not looked up your part number yet to see what you have change but don't think it was the pressure sensor.

Pull the MAP sensor and clean the EGR crud - that rectangular black-plastic sensor is at the top-rear of the head adjacent the fuel filter, attached with a single hex-head bolt, four-wire connector - that other large-hex three-wire sensor back there is the Rail-Pressure Sensor, screwed into the rail, and another at the rear of the rail, the RP Solenoid - don't even mess with them.......................

Thanks gmctd I will get my husband to try that. Of course after doing some running around now the check engine light is off. We are willing to try anything at this point as the check engine light seems to come on and go off so often with our vehicle. Hence why we know have a code reader instead of having to run to the dealer each time as the light is usually off by the time it reaches them.

That code is going to be related to the sensor plugged into the side of the air filter box. The connection may be bad or loose, or the sensor may be bad. Try reseating that plug or look for a new sensor.
