ips stuck

[theelanman]

Driving home this afternoon the gearbox made a clunk the car then stuck in 3rd gear, the engine management light came on and also the gearbox light came on I have turned the car off and the car will now exchange gears but is continuing to keep the light on.......I've just changed battery......

Anyone got any idea?

Not sure what caused it,  might be worth checking the codes but it takes 5 key cycles to disappear if it's a temporary problem. 

[theelanman]

Is there an easy way to read the codes without an OBD reader?.... I've cycled through five ignitions and the light unfortunately is still on

it changes perfectly through the gears up and down and reverse but the light is remaining on

[TAS]

Mine did this a few weeks ago, I disconnected the battery and it reset itself fortunately as I was 300 miles from home.

I've bought an OBD reader and the code is still showing, but it hasn't reoccurred so I haven't taken it anywhere to get checked out.

Did you buy this car from Silverstone?

[theelanman]

No....

I've had it for a couple of years now......

Ok, I had a similar problem with a 2013 IPS (it was also grey), it would lock up in gear for no apparent reason. The dealer would get it going but couldn't diagnose the cause of the problem, Lotus sent a technician to the dealer but he couldn't give me any assurance it wouldn't happen again. In the end I let the dealer off the hook and part exchanged it for their manual demonstrator. It was an unnecessary expense but I couldn't have a car that would let me down without warning.

I appreciate this is not helping much and I hope it's not the same car, disconnecting the battery would sometimes solve it but more often than not it needed recovering back to the dealer. I think it was a software issue but I'm no mechanic. I don't have any paperwork now but would probably recognise the reg if you think it might be the same car.

I'm late with an update...sorry.....

Got to the car this morning and all OK....

All dash lights off.....I thought I'd started the car enough times yesterday to pass the required number of starts after the event.....but maybe I didn't.....anyway......I've ordered an ODB2 interface/dongle.......I'll have a look later

 

Thanks for all the help guys....

Print this and use it as a guide next time

I used both hands for good measure.....

I opened the car, started the car, ran it for a minute, stopped it,  removed the key , then locked the doors.....waited a minute then did the whole procedure again.......x10.......

This happened intermittently to me for years.  Eventually got a engine wiring harness replacement under warranty from Lotus.  The car has been perfect since that was done.

Just happened to my 2016 400 Auto - stuck in 5th, stopped, then will only select Reverse, 3rd and 5th.  Luckily Silverstone were close so they cleased the codes and all ok so far

Hello,

My friend has the same problem with his new Evora .

Do you know what was the root cause ?

[Peegee355]

 After Silverstone cleared the codes and it hasn't happened again even after 10,000 miles

[geartox]

thank you peter for your feedback. 

[geartox]

We got again the problem, but this time we use our obd dongle:

Codes : P0700, P1613, P0751

The car will go back to the dealer...

 

[Jovver]

I had this happen three or four times in the first couple of years of ownership. Since I had the transmission control software updated three years ago, it hasn’t happened at all.

it may be a coincidence of course, but the newer software certainly seemed a step up from the original.

[geartox]

The Evora of my friend has a problem with the shift soleniod sl1 and sl3. 5 weeks later, no news from Lotus for the parts delivery... 

My friend can't drive his car, so he is quite disappointed. 

I don't understand how something like that is possible for a car with this price tag.

Do you think that we can find these parts from someone else ? any idea ?

Its a standard toyota gearbox so presumabley from Toyota. Ive had other bits from them before now.

Hi all - sorry to resurrect an old thread but I now have this problem (2014 Evora S IPS).

Check engine and Check Transmission (cog with exclamation mark lights) on - IPS box only runs in 3rd and reverse.

Codes showing (descriptions from the service notes) are, as you would expect :

• P0700 - Transmission Control System (MIL request)
• P0761 - Shift Solenoid "C" Performance or Stuck Off
• P1613 - Forced Mechanical Limp Home Position

I've cleaned the MAF sensor, and reseated the electrical connection (replacing the existing zip tie - someone's been there before!) as there are some suggestions on Google that this can help. Cleared the codes, but they and the limp home mode recur after around 100yds of driving.

It's booked into Stratton Motors on 17th Feb, but any suggestions in the meantime welcome?

Should I be asking for a TCU software update first? They said it was all done and up to date when I bought it....

If necessary, can solenoid C (part 17, SL3) be changed with the engine/gearbox in situ?

Edit : Standard Lotus labour time to replace one or all of the solenoids is 1.7 hours so I hope/guess not!

When we had the stuck in gear issue was told to disconnect the battery earth lead/s for one minute on refitting earth cable was able too drive as normal although we did take car to local Lotus dealer to check all was ok.

Hmmm... not sure why you cleaned the MAF sensor for those codes but it won't do any harm anyway.

There's a YouTube video that claims, as a possible fix (and as there's a shared wiring harness), that this can help with the issue/codes that I have. Was worth a try..... 🤣

I'd suggest solenoid C is farked.  Or the wiring tower, possible.  You can do the solenoids and the tower from underneath with the sump off the gearbox, from memory (hence only 1.7hrs, otherwise it would be 31.7). Bit of live data diagnostics with the laptop first would be sensible.

I'll try the battery disconnect as suggested by @DarrylV8 when it's not freezing outside but then it's over to Stratton Motors from there, thanks!

Bit of a bu33er as my Emira i4 FE should have been here by now and the Evora gone (now delayed until September...)
