Hi Geoff, Thanks for your reply. I think I might invest in a Scan Gauge, could be very handy. The P0046 code I got from a Toyota Goulburn, so it might be only applicable the 2007 model. I will advise the outcome, let’s hope it’s simple. Regards John.

Hi Fellows. I am in need of some help to identify the cause of my LC200 VX 2007 model problems. I would appreciate any info that other owners might have experienced and their outcomes on fixing it. On a recent trip around the snowy area over the course of a week about a month ago, my truck went into limp mode 7 times. I disconnected the battery to reset the vehicle and then was able to drive on. I was unable to get to a Toyota dealer in limp mode, when I did, the vehicle was not showing any fault codes and was told they need it in limp mode to get the codes. The dash warning lights that came up were, VSC, 4lo, Slip indicator, Malfunction Indicator lights. and was only drivable up to about 50 kph. On the drive back to Sydney the truck was fine. In Sydney my mechanic suggested the fault might be the EGR, so I had it removed and cleaned. A week ago (Sun 21 Feb) while departing Sydney with my 3½t caravan in tow the truck went into limp mode again, this was the first time with the van attached, (obviously it’s not the EGR) my mechanic said this can sometimes happen as the vehicle’s computer relearns the engines performances. A couple of days later I set off again, on approaching Goulburn it happened again. The truck did not have the power to pull the van up the last hill into Goulburn, so I unhooked the van and drove to Toyota in limp mode. The scan show up the fault codes P0046, C1201, B1421, B1424, and B2312. (The 4 last codes don’t apply to my vehicle, so I’m led to believe, they’re probably from the previous vehicle scanned.) The scan indicated the injectors values are OK, suspect fault with turbo boost control. Toyota suggested returning to Sydney and have it repaired here. On the way home it went into limp mode 3 times, once while the truck was stopped at traffic lights. I am now trying to collect any info re this problem so I can make the right decision on what to do. To date the truck has gone into L/M 13 times. Let me say it’s very daunting driving along the Hume H/way doing 50k an hour and trucks passing you doing 110km. Many thanks for your help. John Mc.
