    P0161 is poor O2 Sensor heater circuit performance, could you be missing a number and then have a prefix "a"?

    Diagnostic Code P061A - ETC Level 2 Torque Performance. When Monitored:
    With the engine running; Set Condition: The Powertrain Control Module (PCM) detects an internal error. Possible Causes POWERTRAIN CONTROL MODULE (PCM) SOFTWARE UPDATE needed, POWERTRAIN CONTROL MODULE (PCM) internal failure.

    This diagnosis and repair must be performed at your local dealership.

    P0161-O2 SENSOR 2/2 HEATER PERFORMANCE
    WHEN MONITORED
    Engine running and heater duty cycle greater than 0%. Battery voltage greater than 11.0 volts .

    SET CONDITION
    No sensor output is received when the PCM powers up the sensor heater. Two trip fault. Three good trips to turn off the MIL.

    POSSIBLE CAUSES

    (K399) O2 2/2 heater control circuit open
    (Z902) O2 2/2 heater ground circuit open
    O2 sensor heater element
    PCM
    Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

    Diagnostic Test

    1. O2 SENSOR HEATER OPERATION

    Turn the ignition off.

    NOTE: Wait a minimum of 8 minutes to allow the O2 Sensor to cool down before continuing the test. Allow the O2 Sensor voltage to stabilize between 4.6 and 5.0 volts .

    Ignition on, engine not running.
    With a scan tool, actuate the O2 Heater Test.
    With a scan tool, monitor 2/2 O2 Sensor voltage for at least 2 minutes .

    Q: Does the voltage stay above 4.5 volts?

    YES: Go To 2
    NO: Refer to the INTERMITTENT CONDITION Diagnostic Procedure. See: Component Tests and General Diagnostics
    Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

    2. O2 SENSOR HEATER ELEMENT

    Turn the ignition off.

    NOTE: Allow the O2 sensor to cool down to room temperature.

    Disconnect the O2 Sensor harness connector.
    Measure the resistance of the 2/2 O2 Heater Element, between the O2 Heater Control terminal and the O2 Heater ground terminal in the O2 Sensor connector.

    NOTE: O2 Heater Element resistance values should be measured at 70°F (21.1°C) . The resistance value will vary with different temperature values.

    Q: Is the resistance of the O2 Sensor Heater Element between 2.0 and 30.0 ohms?

    YES: Go To 3
    NO: Replace the O2 Sensor. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

    3. (K399) O2 2/2 HEATER CONTROL CIRCUIT OPEN

    Disconnect the PCM harness connectors.

    CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.

    Measure the resistance of the (K399) O2 2/2 Heater Control circuit from the O2 harness connector to the appropriate terminal of special tool #8815.

    Q: Is the resistance below 0.5 of an ohm?

    YES: Go To 4
    NO: Repair the excessive resistance in the (K399) O2 2/2 Heater Control circuit. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

    4. (Z902) O2 2/2 HEATER GROUND CIRCUIT OPEN

    Measure the resistance between ground and the (Z902) O2 2/2 Heater ground circuit in the O2 Sensor harness connector.

    Q: Is the resistance below 0.5 of an ohm?

    YES: Go To 5
    NO: Repair the excessive resistance in the (Z902) O2 2/2 Heater ground circuit. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

    5. PCM

    NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

    Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.

    Q: Were there any problems found?

    YES: Repair as necessary. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test
    NO: Replace and program the Powertrain Control Module. Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

    I can - I have experienced this twice in one year. the cyllinder heads are broke. Did you all know that all the replacement parts put on your dodge are rebuilt parts... Anyway. having trouble with the No. 2 cyllinder - . They need to fix and recall these vehicles.
