Hardware test result

[Elias2112]

Hi everyone,

I just ran a hardware test on my 21" iMac that's about 2-3 years old.(I'd give more info but its doing the extended hardware test now) Well, I tried Apple support and tried to put the result into Google with no hits either place. So, I'm wondering if anyone knows what this result might mean: apple harware test result - 4SNS/1/40000000:TAOP-41.035

I love my Mac, so between school and film projects I'm working on, I really need it to be working right. Any info would be greatly appreciated. Thank you, Eli

After doing the extended test, I got this code-
4MEM/62/40000000:0xb867ae98

Thanks again for any assistance.

I think is a hardware sensor failing.

I did find some results on google and I remember to have seen this error before.

Oh, the last test you did is RAM problems.

First of all, reset the PRAM and the NVRAM. If resetting both and then doing a cold boot don't help, it's time to take it in for repair, probably the motherboard.

He can reset all he wants but that won't work for HW problems which the OP has, if AHT gives errors there IS HW failure.

That's almost certainly true, however, I found several reports of PRAM and NVRAM resets causing the reported hardware error to stop. It costs nothing other than a few minutes of time, and it won't make the situation worse, so why not try it?

to me it looks like a memory error.take one stick out run the test then take the other stick out and put the first stick back in and try again. basically try each stick on its own. if the error stops you know its the stick of ram.
