Hi all..you've all been kind enough to help before but I need your advice again.
I have a 2001 3.2 auto estate .

A few weeks back the lights on auto selector didn't all light up when in respective gear then they all came on !!..then after a while if in D .light would match up and all ok.

Then about a day a go when in D ,didn't feel like it had changed down and struggled to pull away as if in too higher gear..then got TC light on.sport mode wouldn't engage either but box works fine if manually used.

Today whilst driving along engine just cut out!
Wouldn't restart .
Left 10 mins then it started and stopped again ..cut out.
Towed home and then it started again ok.
Tick over not as even as before IE wandered between 500 rpm and 800 rpm.

My question is it reminds me of crankshaft sensor fault and I wondered if it was a mixture of crankshaft sensor and the fact that selector box needs cleaning ..are the two items connected and could this be throwing up gear box/TC issues?

Also what's the service interns for cam belts..hope someone can advise on this issue as I enjoy the car ..mileage is 108k

Sounds like crank sensor failure and gear selector switch needs cleaning.

Do the crank sensor first!

[darren757]

Thank you for advice..do you know if crank sensor can cause gearbox /TC issues?

[Gaffers]

Thank you for advice..do you know if crank sensor can cause gearbox /TC issues?

No.  They are two separate issues that need dealing with individually.  Crank sensor is the most critical.

[Terbs]

Regarding the cambelt....its 4 years or 40,000. Do not disregard.!!!!!!
However, if you have not got absolute proof of the last one being fitted.....do it now!!!!!!!!! And its not only the belt, you need the whole kit, which includes tensioners.

Well documented on here, and disregarding will lead to you owning scrap on wheels. (this is coming from someone who has had three belts let go on various cars, through not knowing about these things 

If the years come up before the mileage....do it. If the mileage comes up first....do it !!!!!!

And do the auxiliary belt at the same time  not sure about the tensioner on the auxiliary belt someone with the knowledge wll know.

Hi all just cleaned gear selector switch and worked perfectly before I started the engine all idications as they should be corresponding to selected gear.

I've just changed crank sensor and run car and fault I had before with gear indications are back
1 3 R work correctly
2 d n p ..all lights are on on gear indicator .

I don't know if anyone else has had this?
Selector switch was fairly clean in side and I used switch cleaner on all parts.

Has anyone got any suggestions what problem might be?
Thanks

Still selector switch



Thanks for help on this ..switch tracks looked worn in certain places ..ill get another switch and try it!!

[darren757]

Thanks for help..has anyone had this issue before ..it also knocks the TC out ..just abit puzzled by the fact after rebuilding switch it went through all selections perfectly then when I ran the engine is was straight back to its old tricks

[Bigron]

Would it be too silly to suggest checking the gearbox ATF level?

Ron.

[darren757]

Gear level is fine ..it seems to be the logic or system that signals the appropriate gear position to light..its just one of those situations where it's how much money do you throw at it for me !!
It's been a great car and is due timing belt as well..if the transmission is on its way I'll just crush it .

What ever the fault is it knocks out the TC and sport mode as well after a period of driving

[05omegav6]

It's a simple fault... If cleaning the switch as per the guide hasn't sorted it, then a new switch is probably in order...

First thing though is to ensure that the contacts are clean and dry within the plugs

[darren757]

Thanks again ..will get another switch and try it!!

[darren757]
