donnyburger Posted May 29, 2016 Share Posted May 29, 2016 Good afternoon all. I'm having an issue I'm currently trying to sort a problem out on my ('97 auto) EJ25-powered camper that I've driven around for the last 2 1/2 years! In short, it cuts out intermittently at junctions and has done since I bought it. I have been in touch with RJES yesterday, and we found that there was a slight issue with the wiring harness which meant the VSS and check engine light (LED) weren't getting power. This has since been corrected. After that, I disconnected the Battery last night and left it until this morning to reset the ECU. I've taken it for a drive today, and...no change! I have checked the feed to the VSS which goes from 0v to 12v when ignition is turned to 1, so there's no issue there. I plugged the 2 black diagnostic ports together, turned the ignition to 1 and I got a blink code of 33 - VSS again. Since then, I have just found one of the small vacuum pipe that goes from here - to here - had a very small hole in it, which I have just sorted by shortening it slightly - Now, I've disconnected the Battery again, and I'm of the understanding that I need to leave this overnight to reset it completely. Before I did this, the engine LED still showed me the '33' VSS code which really has me baffled! EDIT - I've just read that I might have to the the Battery disconnected for 24 hours. This isn't an issue really, just an inconvenience. Can anyone help?! Please! Quote Link to comment Share on other sites More sharing options...
stants Posted May 29, 2016 Share Posted May 29, 2016 Hello, You don't need to leave it for 2r hours, just press the brake pedal till the lamps die that will drain all residual power then just leave 20 mins, What gearbox have you got mated to ? The vss is probably to do with it not reading a correct signal from the box or a fault with the wiring in the speedo Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...

It's mated to the VW AAP gearbox that the bus came with. The reason I'm trying to sort this is that it vetoed the bus selling yesterday and has put my next (deposited) purchase under threat.

stants Posted May 29, 2016 Share Posted May 29, 2016 What clocks is it all mated to ? May be throwing a wobbler at the at end too Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
donnyburger Posted May 29, 2016 Author Share Posted May 29, 2016 To the original clocks, which read correctly (compared to sat-nav) It's a very common conversion. I've also been told that there's a chance that it could be the idle control valve, which is a fiddly, careful job to do? Quote Link to comment Share on other sites More sharing options...
donnyburger Posted May 29, 2016 Author Share Posted May 29, 2016 I've also just given the idle control valve about a 1/4 can of carb cleaner in where the hose connects. Hopefully that'll help. Quote Link to comment Share on other sites More sharing options...
donnyburger Posted May 29, 2016 Author Share Posted May 29, 2016 ...aaaaaaaannnnnddddd that's made no difference! Now the LED is a constant blink. Neither the long or short flashes usually described by the index. *runs of to google* Quote Link to comment Share on other sites More sharing options...

Guess I'll be removing the idle air control valve tomorrow and cleaning it up. Seems it could be what's causing my issue. Thanks. :) Quote Link to comment Share on other sites More sharing options...

Thanks. :) If you do remove the icv make sure you don't undo the adjustment screws on the top without marking the original position first [emoji6] If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
donnyburger Posted May 31, 2016 Author Share Posted May 31, 2016 Just to bring this to a conclusion, it appears we are all now well and good. No stalling at junctions, no engine LED warning lights. Thanks to all involved, in short it was a combination of the wiring error and a filthy IACV which was removed, cleaned up with carb cleaner and cotton buds and re-installed along with another little vaccum leak I found, then a final ECU reset. :) 2 Quote Link to comment Share on other sites More sharing options...
