    In the last few weeks I have seen several people post about oil sender codes and when you read the post you find that they Pulled the code using the DIAG mode in the cluster. This was pointed out on a bullit website sometime ago and is misleading some into thinking they can diag a check engine light with this. or that they need new senders when in fact the readings are normal.

    The DIAG mode and the codes pulled using this method is codes for the cluster module and does not include codes for the PCM,ABS or any other modules.

    Plus the codes pulled are hard faults and it's normal to get hard faults for the oil sender when running this test with the engine off.

    If you have a check engine light on go and get the code scanned for free at a auto parts store or bring it to a shop to get it fixed.

    :bs: LOL J/K

    But yea I was one of those under the impression that the code check would display any codes thrown...but I guess not haha. Yet again, good info man :nice: .

    Thank goodness for this sticky. Sad stories where people have already bought a new sending unit and replaced it trying to "fix" a problem that doesn't exist.

    From my experience, you can get codes from the cluster in Diag mode, but there is one code that ALWAYS comes back, and it is only a problem with the cluster. If I remember right the code is for a oil pressure switch, I forget the actual code though.

    I have gotten codes from the cluster that matched codes from a scanner, but this is not a final tell all tool.

    no offense but your either wrong or don't understand that there are B,P,U codes and that there are multiple modules, and the cluster DIAG mode does not test the other modules for codes.

    B codes are related to the body system and B codes generated by the HEC module can be displayed by the cluster.

    U codes are communication faults. since the HEC is the hub for the network you will find fault codes by using the cluster DIAG mode, since these fault codes are genreated by the HEC.

    P codes are powertrain faults generated by the PCM and are not availible in the cluster diag mode.

    the diag mode is for us to test the guages and to put the cluster in self test mode. it will not read codes for other modules.

    those are the codes you can pull in dealer test mode, now please tell me where in there is codes for the PCM or abs system or any module other than the HEC?

    just as a example I went on set a few codes on my car on purpose and did a little experiment.

    I disconected my maf sensor and IAT and then after runningor a few minutes disconected my IAC and then shut it down by letting off the throttle.

    I then restarted the car and had the CEL on and then did the dealer test mode

    in dealer test mode i came up with these codes.

    d262 missing scp message

    dtc 5284 oil presure switch

    now with my sct2 i read the codes and came up with this.

    p0102 maf low circuit input

    p0113 IAT low input

    p1504 IAC malf.

    If this is not enough proof for you i will make a video if you want.
