    Unhappy P1481 fault code

    Hi everyone,

    This is a long shot, but maybe someone here's had the same problem...

    Every couple of weeks my car seems to log a P1481 fault code. I've had it into a dealer three times and each time they tell me that since there's no fault present at the time they drive it, there's nothing to fix. They just drive it around for a bit, and clear the fault code.

    As far as I can gather, the code has something to do with "1st stage engine cooling fan". I have no idea what conditions are required to log this code, so I can't really guess what the problem might be. My engine isn't overheating, so I assume that the radiator fan is working.

    Has anyone had (and fixed?) this code before? Or have any suggestions on what the problem might be?

    Ta.

    Haven't had that mate (touches & rubs wood madly).

    The flipin' dealer should be able to tell you what the fault code is. Dills.

    I'm the same as Ozz mate; I'm surprised the stealer can't tell you what the fault code is. They should be able to read how often you're getting the code as well.

    Try a second opinion at a different stealer.

    Thanks Ozz and AJA. I agree, the dealer should be able to fix it. But they reckon they can't actually determine the exact cause of the fault unless they happen to have a Tech 2 hooked up to the car at the time it logs the fault code. I have a heap of service dockets that tell me how often I'm getting the fault code...

    The dealer's service manager has the car at present. The plan is that he's going to leave a Tech 2 hooked up to it and that by some miracle the fault will appear while he's driving it. I'm not holding my breath...

    They can tell me what the fault code means, they just can't seem to determine what the problem is...

    Thanks Rob. I have a MY03 Holden Vectra CDXi, manual, Z32E engine.

    When the light comes on, it will come on for at most 10-15 seconds and then go off again. The load on the engine doesn't seem to make any difference; it will happen under full throttle with the A/C on or it will happen at idle with the A/C off. The engine isn't overheating - the engine temperature guage usually shows around 85 C.

    Please let me know if you require further information.

    Default p1481

    have had a look and the most likely fault would be engine cooling module this is situated between fans and has the wiring for fan built into it. the relays for fan control are built into this. i can also see why agent is reluctant to do anything about your problem as the test steps involved are very involved.
    you might want to check out fuse 35 and 36 in underhood fuse box as these are the only fuses that control this cooling module.

    hope this helps.

    I checked the fuses and they are OK. I should mention that this is an intermittent problem; sometimes the fault will not occur for a month or more, other times it will happen five times in a week.

    Out of curiousity, what's involved in the "very involved" test steps?

    Thanks.
