Mike25tt Posted August 29, 2014 Share Posted August 29, 2014 These codes come up: 2b Freshair Abnormal refrigerant pressure 10 Front Demist Fault in solar sensor circuit. (Might be normal if in dim light conditions. Try again while in bright sunlight, or shine a torch into the solar sensor at the base of the windscreen.) Is it more than likely that my condenser is shot? Or a corroded pipe in the system? Or just simply needs re-gassing? I'm thinking about getting it pressure tested before replacing parts. Any help is appreciated. Quote Link to comment Share on other sites More sharing options...
peter richards Posted August 29, 2014 Share Posted August 29, 2014 hi mate , in the other thread I thought you had done all the tests , mine was regassed with a dye in it , didn't last long so the specialist found the leak (condenser) I think UV light shows it up . anyway get it tested and gassed it might be ok , fingers crossed, normally if there is a problem the machine shuts down on a re gas Quote Link to comment Share on other sites More sharing options...
Mike25tt Posted August 29, 2014 Author Share Posted August 29, 2014 Hi Peter. Stupidly I'm going about it in the wrong way. Mainly because of the expense of sorting the ac on my yaris. Getting it regassed, losing that, then getting it pressure checked (fault with the condenser) replacing the condenser then getting it regassed again! So I have jumped to the conclusion that it's the condenser at fault on the supra before getting it pressure tested. I never knew about the diagnostic test. I guess because I've never had the problem up until now so never looked into it. I found a thread on it the other night. I'm not bothered about the solar sensor fault because it was over cast when I checked. So that just leaves the abnormal refrigerant pressure. I seem to remember trying to engage the compressor last year by topping the refrigerant pressure up with one of the halfrauds kits but to no avail. Maybe a re gas is all it needs? Hopefully I can get it pressure checked tomorrow morning. Quote Link to comment Share on other sites More sharing options...

Scooter Posted August 30, 2014 Share Posted August 30, 2014 I take it you've looked at the front sight glass when someone else starts it up? if there is nothing visible it suggests a leak with a likely contender the condenser but i've had a valve fail behind the dash that stopped mine. A specialist should be able to tell very quickly, either the fluid will flow but the pressure drop ie a leak or the pressure just ramps right up indicating a blockage.

Mike25tt Posted August 30, 2014 Author Share Posted August 30, 2014 Yeh I've looked at the sight glass and that was clear so most probably is a leak somewhere. I couldn't get it tested today but got it booked it Wednesday. Hopefully it will be a cheap fix. Quote Link to comment Share on other sites More sharing options...
