P0526-17 (28) Fan speed sensor circuit - General electrical failure - circuit voltage above threshold

[Jimmy Brooks]

Great to know Jimmy - my battery is new a few months ago so keep that in mind. I checked my scanner again today and I'm still code free (not counting my chickens though!). I was getting this code (like you a fuel pump issue):

Which went away with the aforementioned battery change... Keep me posted, misery loves company!

Yup! That’s the same code. Weird, I’m very sure it’s voltage related and we probably have the same issue. I’ll be around the car more in the summer to tinker and play with a few things. I’ll keep you posted if I find anything but I suspect it’s ground related (I’ve replaced the alternator so I’m ruling it out… for now)

On a side note I need to replace the fan clutch (clicks a ton in the cold) but I don’t think that’ll fix the code. Again, I think it’s voltage related.

Hi @Jimmy Brooks - Please keep me posted as you tinker over the summer and I'll do the same. Having replaced the viscous fan and the battery but not the alternator I'm in a slightly different position from you. FWIW's I purchased the Mahle viscous fan from Rock Auto, it was $323 but now appears to have gone up to $349. I think this is OE as they had Land Rover scratched out on the plastic portion of the fan, everything else looked identical.

I will keep an eye on the voltage as well.

Bear in mind that I did reseat some grounding points just behind the front passenger side headlight.

Are your code always present or intermittent?

Here's the viscous fan at Rock Auto:
