    DTC P0072 cant't be cleared after installing a new ambient air tem sensor twice

    Hans replied to Hans's topic in 3rd Generation Dodge
    I noticed the Voltage fluctuate at Idle every 3-5 seconds between 13 Volts and 15 volts . I am going to replace the batteries and maybe the alternator. P2509 is also still there.

    Thanks, yes I saw that earlier and have not tried out everything. Hoped I would never have to go close to the ECM

    DTC P0072 cant't be cleared after installing a new ambient air tem sensor twice

    Hans posted a topic in 3rd Generation Dodge
    I would like to clear the check engine light and clear (permanent?) DTC P0072 so I can smog my truck. P2509 also comes up. Dealer wants to flash the PCM for $175. I already repaced the ambient air tem sensor twice, wireing inspected... Two years ago P0072 went away after installing the new sensor. Thanks 5 Volts are going to the sensor and the sensor reads 11000 Ohms. Is there any way to clear codes on a 2007 5.9 ? My Bosch OBDii scanner erases every code except the P0072. Clains the current is low but it has 5 Volts going to the sensor.Truck runs perfect except for windshield wiper electrical flaw.They stop in the middle of the window and the lowest setting doesn;t work.Noticed that the windshield wipers are on the same wiring group/diagram. Mabe a corroded ground?
