Hey,

This has happened around 4 times since ive had the car, and it happened yesterday. Ill be driving along, then all of a sudden the (check engine??) light in top right hand corner comes on, (at the same time yesterday as well the TRC off light came on and i couldnt turn it off) then you start slowing down, like the cars turned off but it still has power, put your foot down nothing happens.

Then i eventually come to a stop, turn the car off, turn it on and its sweet again, drives fine.

Anybody else had this happen to them. Once you turn the car back on its fine like nothing happened.

It's going into limp mde for some reason, you need to take it to someone who can get the codes and find out what's wrong with it. Toyota dealer would probably be my first stop

I dont think its limp mode.

Car still has power because ign is still on, motor is still spinning so power steer keeps working, but engine is not firing.

Limp mode allows you to continue driving.

You have some sort of intermittent fault with the computer or critical sensors. Like your crank angle sensor has dropped out (ie not sending a signal).

Get a lexus service center to run diagnostics.

Bridge E1 & Tc on the diagnostics connector in the engine bay, then follow this guide to work out the codes:

Reading Error Codes from CEL

Then look them up in the attachment to this thread, look for the two digit code in brackets

Nah he says he still has power, just no go when he puts his foot down.

Guess we'll just have to wait and see what he comes back with...

The car has stalled, engine and all its accessories are being driven by the momentum of the car, makes quite similar noises to when the engine is running.
If it were in limp mode he would be able to continue driving, with imposed conservative ign timimg and rev limits.

If you can get codes outof it then thats good! Get to it!

haha,

Yeah, ill get right on it when i get a chance. On the weekend probably,

thanks for the replies

I had exact problem like this when I had my Supra 5 years ago , you could be driving or coming to a stop and all of a sudden all the lights on the dash comes on and engine just turned off , and need to fire it back up again .... the only thing I realize was power steering was off too

Any codes?

I'll be keen to hear the results of this, i'm getting pretty much the same issue with my 6mt rs200.

I have the same problem with it trying to stall intermittently but if you put the clutch in and rev it fast enough you can catch it and keep it driving... I believe it may be the TPS and need to find a good one to test this theory.

The biggest problem is how far between faults this is so it is really hard to find.

It happened to me when I was loosing traction in the wet. The light came on but I could still drive. I think it was because I lost traction.

The traction light would have came on but not the engine check light.... that's just from loosing traction with traction control on.

Its most likely the TPS or Electronic Throttle Control motor, like its been mentioned before try and get the codes off the ECU, that will point you in the right direction...

Leiden you been lurking round here for a while? Nice to see you back

Yeah i know....after posting that i planned on getting the codes but then forgot about it. It hasn't happened since.

If it only happens once every 6 months + then its probably not worth it for me to go and have it looked at after getting the codes.

i would still get it looked at... its like having a flat tire with no spare.

Just been moving house after starting a new job and have only got the internet sorted, good to be back :)

Hey guys,

Ok i just thought i'd post a response on here regarding a pretty similar (if not possibly the same) issue.

To be specific, the problem with mine was easily reproducable simply by reving the engine to past 6-6000rpm or so, in which case i would almost always get that same behaviour - engine light coming on, and the engine going into some sort of a safe mode forcing me to pull over and restart the car, in which case i could drive off as normal.

I took it to a mechanic and it would appear after getting the code checked out etc, the issue was in the throttle body, basically i need a new one. Apparently it is a known fault?

I wouldn't say whole throttle body, but the throttle position sensor (TPS) on the throttle body is a known fault. Talk to xNickx for a price on one, and it's a job you could do yourself if you have a couple screwdrivers.

Thanks for the heads up Solied Altezza :), well in the case of mine it looked like the sensor itself was beyond repair and i had to get a replacement from Toyota. Just got the car back yesterday and it now drives beautifully.
