Atts Left & Right Pressure Sensors

Post by **clarelude23** » Thu Mar 09, 2017 4:13 pm

They're £420 new delivered to Ireland for the pair so anyone with two good second hand ones let me know. Its giving codes 62 & 64. Can they be tested for function/fixed I wonder? Thanks in advance.

Download the 5th gen service manual (the one with links) from the wiki. See section 15-49 (PDF page number 750), there is a flow diagram on how to test the sensors.

Not gonna lie i have codes 63 and 64 too, one of the issues i found was with the radiator which was absolutely ruined and leaking all over the place. On removing it i discovered something i wasn't aware of before, the fact that the type s uses an auto radiator to make use of the bottom oil cooler, normally used for cooling the ATF on an auto car. Instead it utilises this to cool the ATF in the ATTS system, you can see the lines running over the top of the gearbox and down towards the bottom of the rad.

What i found was the coolant had leaked and ruined any protective coating on the hard line part of the plumbing for the ATF lines going into the rad. This resulted in much corrosion causing the ATF to leak thus reducing pressure and causing those codes to be flagged.

Now im not saying this is definitely the issue on yours as i have a few other issues with the ATTS im yet to tackle (too busy with other projects) but i would highly recommend checking the lines where they go into the bottom of the rad and checking for any coolant leaks too. Check that the top and bottom rad hoses pressurise once the car gets up to temp, if they dont you probably have a coolant leak which may be the root cause of the problem.

The rad itself is not expensive, i only paid £38 delivered for mine and it was spot on, and i just used some silicon hose to replace one of the hard lines for the ATF. If the issue is similar to mine then you may find replacing the rad and topping up the ATF resolves the issue.

Have you had a good root around underneath yet or just going off what the codes are telling you?

Just realised you said 62 not 63, but both point to the pressure sensor...

£420 delivered for both

Its £420 for one. I hope you're aware it's a gearbox out, atts out job just to change the sensors. The top oil sensor failed on mine. I gave up and binned it and went Lsd.

Yup Ratty,sorry thats just for one. Bollox. No leaks from rad and I changed the Atts fluid last week and there was plenty fluid but cheers for the input. Well il be having the gearbox off in the coming weeks to fix my 5th gear grind so that may work out. Expensive times

15hours of labour just to change a sensor. After spending 10 hours removing the gearbox is a further 5 just for Atts. Thanks Honda.
