steve spedd Posted April 3, 2017 Share Posted April 3, 2017 Evening all, Wondering if the Supra experts can assist or suggest something! Bit of background.... Cars a NA-t running an FFIM and was working perfectly. Been off the road I'd say a month in which time I've fitted the following: New steering rack New front brakes New bonnet (with holes/vents); suspect this is the issue Anyway... Now the car won't rev above 2k; presume it's in limp mode? Now my initial thoughts were its electronic as it idles fine so could it be because something has got wet? If so what should I be looking at or what are the common parts to fail if they are wet? Granted I've not yet checked all fuses but doubt this to be that. I have taken a little look at the map/TP sensor and looked wet but I've given it a good soak in WD-40 and didn't fix it. Not sure if this needs drying properly? Any advice? booked in for a Mot Saturday Thanks. Stephen Link to comment Share on other sites More sharing options...
RobUK Posted April 3, 2017 Share Posted April 3, 2017 You need to check diagnostics as it could be a sensor that's been disturbed Link to comment Share on other sites More sharing options...
steve spedd Posted April 3, 2017 Author Share Posted April 3, 2017 Will do. Need to get my hands on a reader... I hoping everything is just wet and needs drying Link to comment Share on other sites More sharing options...
RobUK Posted April 3, 2017 Share Posted April 3, 2017 You can do through bringing 2 pins together on the diag port, search diagnostic port and it will come up... Link to comment Share on other sites More sharing options...
steve spedd Posted April 4, 2017 Author Share Posted April 4, 2017 Bit of an update.... Cleaned everything and still no joy. It feels/sounds like it's miss-firing. So if I unplug the TPS she runs, granted rich but she runs fine So is this a new TPS due to getting wet or have a blown a fuse/loose wire? Any ideas?

Pulley Posted April 4, 2017 Share Posted April 4, 2017 Sounds like the tps has gotten very wet and needs drying out Check the resistance values across the sweep range There's info on here in the pinouts and values at various positions Link to comment Share on other sites More sharing options...
steve spedd Posted April 4, 2017 Author Share Posted April 4, 2017 Cheers I'll take a look at that. I've got a spare TPS so if I'm getting the right volts and good earth will swap it over Link to comment Share on other sites More sharing options...
Mike2JZ Posted April 4, 2017 Share Posted April 4, 2017 Do the holes in the bonnet allow water to fall into the spark plug wells? Link to comment Share on other sites More sharing options...
steve spedd Posted April 4, 2017 Author Share Posted April 4, 2017 No I've checked them. It's 100% to do with the TPS mate. Just think it need a new one :/ Link to comment Share on other sites More sharing options...
steve spedd Posted April 6, 2017 Author Share Posted April 6, 2017 All sorted. One wire had split a little (22 year old engine loom!) and the TPS was faulty due to water damage. Runs like a single turbo should now Link to comment Share on other sites More sharing options...
