    Consequences of not replacing MAF sensor?

    Hey all,

    Engine and traction light came on the other day, took it to get diagnosed and was MAF sensor buggered, and "Engine Torque Malfunction". However, car does not run oddly, idle is fine, as is boost, overboost etc. No problems I would associate with MAF blown (though I am new to the ZLET). Guy cleared codes, and as I left they both came up again. Techie reckons they are ghost codes.

    1 - What is engine torque malfunction? MAF gone out of range and cannot read properly?

    2 - Do you notice on the ZLET when the MAF sensor goes? Car drives EXACTLY the same - no different.

    If MAF has gone and it's not a ghost code, what would happen if I don't replace MAF asap? Other than maybe killing cat with dodgy fuelling! Or any other ideas? Would the MAF sensor come loose? Not checked the basics yet, get home after dark and go to work in the dark

    Cheers

    Chris

    It's not worth the risk - why don't you just replace it?

    It's very likely that your car won't be fueling correctly, and you could be risking dmamge to you engine as well as cat.

    Because the MAF is reading incorrectly it will doubt cause the car to run lean top end and then eat the bottom end and spit it out.

    For the cost of less than £100 it will save you over 2k in rebuild costs.

    The MAF is what the engine uses at full throttle to get the mixture right. If you don't change it your damage your engine.......

    I am going to change it, don't get me wrong! Nice excuse for a VXR MAF to help with the remap. Was just wondering if these are typical symptoms of MAF failure on a ZLET, just seem rather mild tbh

    eng. mag. light pops on, then goes out and leaves the TC light on. Idle gets a little rough but after a restart it rests it back to normal for a bit.
