Topic: goes to garage comes out with two sensor lights on..! (Read 6461 times)

mr smith · « **on:** June 08, 2012, 10:03:04 AM »

so the jeep went in for a little TLC..
swap out the steering box, check all brakes whilst on ramp, grease up clutch at pedal end, oil/filter..
nothing too major
then as i'm about to drive off i notice the engine management light is on and srs light.. so i went back in..
he told me they were on when i dropped it off (most definitely were not!) then enlightened me they checked the fault back to a throttle body sensor.. now running a bit lumpy until i sort, going to get on the phone now and have a rant because can it really be coincidence that a fault is thrown as i dropped it off!? me thinks not..

Sounds like somebody never to use again.

mr smith · « **Reply #2 on:** June 08, 2012, 10:37:10 AM »

i'm suprised as they come recommended.. lets see how they deal with it
what could they have done to throw those sensors under the works undertaken..?

they are a local garage to me.. harris mayes country cars in rickmansworth

Did they disconnect the battery? It's a long shot but for you to have those two lights on they must have done something like that. Also get them to scan the ECU

mr smith · « **Reply #4 on:** June 08, 2012, 04:54:43 PM »

so the garage have accepted the car back today and given me a run around.. they have updated with the following this arvo:

- engine light is reading back to throttle position sensor, they have tested and is giving the same reading regarding postition, so it appears this is a coincidential fault..? they are awaiting to find out from jeep if this is an expensive item or not..?

- srs airbag warning light, they have said has come back with no fault, however if they have replaced the steering box they have said it could be possible that the sleeve on the steering arm has been turned or got dirt on it when adjusting the steering hence giving a fault, they are having this apart again tomorrow to check..

what do you think..? anyone know if the throttle position sensor is an expensive item?

disconnect and charge the battery and then try again.

Theres definitely a strong whiff of

I don't know about jeeps but in vw's there is a clock spring under the steering wheel that tells the car that position of the steering wheel, if the steering is adjusted so that sensor is not in the right position when the steering is straight it will throw up a warning and it turns the abs and airbag light on just to warn you that they are not operational.

Jeeps do have clock spring and it is easily broken if care is not taken when replacing steering parts. They do not take well to any extra revolutions.

Jonny Jeep · « **Reply #11 on:** June 08, 2012, 09:09:14 PM »

Since they've swapped the steering box it's very possible the steering wheel was rotated when the box was disconnected which can easily break the connector in the clockspring. It may come down to your word against theirs, but, I'd insist on seeing the risk assessment for this kind of work, to find out what procedures they have in place to ensure clocksprings don't get broken. If they can't produce a risk assessment right there and then you need to be asking for the details of their liability insurers so you can take it up with them.

Clocksprings go by other names too I think rover called them rotating couplings. All vehicles with steering wheel airbags have them so I don't see they could argue about not knowing bout them and the risks involved.

As your TJ is a 2001 you don't need them t check codes anyway. you can do it by turning the key on-off-on-off-on and the codes will display in the odometer.

It's been reported that bad clocksprings can cause TPS codes as they share a common connection within the PCM.

Risk asessment?

I should think if he asks that he'll have no chance of being taken seriously.

mr smith · « **Reply #13 on:** June 10, 2012, 07:07:35 PM »

Will see what they say tomorrow.. they kept the car over the weekend and said they were going to check the clockspring.. either way i have stated that no lights were on when they received the vehicle.. I wasn't able to contact them at all on sat which was a tad annoying but hey ho i'll let them crack on with it and see what they say tomorrow..
Thanks for your comments gents..

As above, sounds like they have turned the steering wheel too many rotations when the box was out and broken the clockspring, or attempted to straighten the wheel by rotating it which would be the reason the airbag light is on, although the FSM states the clockspring cannot be repaired, in fact it looks possible to me (looking at my old one) if you have a steady hand with a soldering iron, a new one will set ya (well them) £132.52 - well thats what mine cost 18 mths ago. My suggestion would be to ask them to remove the clockspring whilst you are present and then you will know if it is broken or not, its only a 10 minute job. When they remove the clockspring make sure they dont rotate the steering wheel so they dont turn round and say it broke there n then.

Delk · « **Reply #15 on:** June 11, 2012, 05:41:09 AM »

Does the horn work? It goes throught the same clock spring.

Jonny Jeep · « **Reply #16 on:** June 11, 2012, 06:40:04 PM »

The trouble with elfen safety and liability these days you seem to need a risk assessment for most things. If they don't have one for something that can easily be broken it's ammo against them. When I've had my steering gear off before I center the steering wheel and put the seat belt though the bottom of the wheel and fasten it before disconnecting the steering.

FSM has a procedure for checking the clockspring is centered. You need to remove it and gently turn it till it stops. Then gently rotate it the opposite direction till it stops. Rotate back half the number of turns between stops and the thing is centered. Obviously if it just rotates without stopping it is broken. If that's the case it's down to them as far as I'm concerned.

mr smith · « **Reply #17 on:** June 11, 2012, 07:53:53 PM »

well they had it over the weekend and as far as i can tell managed to check the battery and not answer the phone to me!
not impressed..
have sorted a new throttle body sensor as i could do it cheaper and quicker and i shall be rocking up there tomorrow to see what has been done and or ask to see the clockspring whilst i'm there...
i really dont want to drive the torquoise freelander that has no oil and tyres that were nearly flat and a slipping fan belt any longer!
new garage please!

I know of a very good Jeep trained mech who lives in Colchester who is reliable and honest and knows his Jeep stuff, pm if interested and Ill give you his number.

x 2 on what Delk says, check if the horn works, if the horn don't work and the airbag light is on, it is 99% defo the clockspring is broken.

mr smith · « **Reply #23 on:** June 12, 2012, 05:09:31 PM »

ok so i have been updated by the garage thus:
- we do not know why the srs light is on and cannot resolve, have checked what they can!?
- the engine light which reads to throttle position sensor, has been replaced with new as supplied by customer and has not cleared fault!

to which i have responded:
- i feel it is highly likely that the clockspring is broken from works undertaken due to the fact tha horn is not working, i'm guessing as a result in over turning the steering wheel when the box was off.
- i also feel that the engine management light which is triggering a throttle sensor code has been perhaps triggered by the works undertaken, perhaps damaging a connector or breaking a wire whilst dealing with battery and so on..?

I have contacted my trusted garage which i originally undertook works - London Jeep Specialist in Enfield and they are collecting the car on Thursday and limping it back to them (as it is stuttery to drive with whatever the engine fault is - apparently sensor is reading as fully open although it is not)..
They have straight away clarified the obvious clockspring and will investigate further giving me a report based on works done previously so i can return to the other garage and demand my monies!
What a ball ache just to replace a steering box which Bulldog supplied (cheers by the way.. that works!)..
I'll let you know what London Jeep say, as i know i can trust them..

I also just did the key thing for the code which came up as P0123..

Gordy - cheers chap but a little too far for me.. I do know that london Jeep are worthy.. and a bit closer, especially since they have offered to collect during the week which really helps me as it is a daily..
