    Cylinders 2,4,6 located on driver side. Check contention on O2 wires, if im not mistaken I had simular problem due to bad connection, just spray some ececrtic connection cleaner on harness and then plug it back.
    And what was the reason for u to replace all O2 sensors. Did u got error codes on them?. I replaced only 2 that before catalyst, after catalyst still original with 165k on them

    ----------

    Thats what I found on my AllData.com
    IMPORTANT: The harness must not contact any of the hot exhaust components. The rear Heated Oxygen Sensor (HO2S) pigtail has white tape at the intervals, indicating the proper location of each retaining clip. When connecting the sensor pigtail to the harness ensure that the connector seal is crushed uniformly all the way around between the connectors.

    ----------

    OEM part # for O2 sensors:
    Before catalyst: 9198809
    After catalyst: 9120293

    Re: need some help

    I changed them for two reasons 180,000 miles and I was I was getting code P0411
    I have done everything I could think of even took it to the shop had a smoke test, checked the
    air pump running find replaced the Air Bypass Valve, replaced Air Pump Check Valve, Air Bypass Valve ,
    and the intake Manifold Tuning Valve still p0411 last thing was I replaced the 02 sensors well the p0411 is
    gone but the codes p01141 p01161 p0141 p0161 replaced it. My car I love it and hate it at the same time.
    if you like I can post what my scanner says it has all the real time data.

    Thats really weird... all o2 sensors u replaced not connecting... I dont think its a fuse, but its always good to check! Pull every single fuse and check it. It was a tread here on forum where guy had all o2 sensors codes and by replacing secondary air injection pump fixed all that

    Re: need some help

    Might want to check fuse 43 in the ECM housing.
    Looks like you have 4 out 6 of these codes for the heated o2 control circuit.

    From the manual:
    Using the scan tool, observe the DTC information.

    Are DTCs P0135, P0141, P0155, P0161, P1141 or P1161 set?
    --
    Yes, Go to Step 3

    3
    Turn OFF the ignition.
    Inspect fuse 43 for the oxygen sensor heaters located in the ECM housing.
    Is fuse 43 open?

    Re: need some help

    It's probably that little green one on the far left. It's supposed to be a 30 amp fuse and that's what that one is. The component locator shows #43 above that orange relay and it doesn't show the little green one, so that's probably it. It wouldn't be the first time my manual shows a component in the wrong place. It showed relay k134 in the wrong location also.


    (1) Additional Harness
    (2) Fuse #40 (30A)
    (3) Fuse #52 (30A)
    (4) ECM Ground
    (5) Connector C110
    (6) Coolant Fan Test Connector
    (7) ECM Module
    (8) ECM Connector C1
    (9) A Fuse #42 (40A) B Fuse #49 (50A)
    (10) Fan Control Relay (Orange)
    (11) Fuel Pump Relay (Violet)
    (12) P108
    (13) Additional Harness to Battery
    (14) Instrument Panel Wiring Harness
    (15) P104
    (16) I/P Harness
    (17) Fuse #43
    (18) Engine Controls Power Relay (Violet)
    (19) Fan Control Relay (Brown)
    (20) Fuse #50 (For Fan Control & W/W Motor Relays)
    (21) Fan Control Relay (Gray)
    (22) Fan Control Relay (Green)
    (23) A/C Compressor Relay (Green)
