I have just today had my front o/s ABS sensor replaced with one from Honda dealers, when the mechaninc replaced the sensor, he said there is is still a fault in the wiring somewhere, and couldnt clear the VSA and ABS lights. Said the car will drive fine, but needs looking at by a auto electrcian. Going to see if I can find a decent auto electrician tomorrow.

Anyone else experience anything similar...??

Many thanks....
 
So you had your car in at Honda to resolve a VSA light. They replaced a sensor but the fault light remains? I think I'd be going back to Honda for them to sort. No doubt they've charged for the sensor. Was it actually needed?

***uming that there may have been several faults and they have correctly replaced a faulty sensor have they told you the fault code that remains. I would have thought that Honda should have been able to diagnose faults on their own systems. Seems a bit odd to me.
 
Agree with Paul
 
The car will drive fine mate but the ABS and VSA system won't work properly. Who fitted it and what is the error you're getting? It's possible the sensor wasn't installed properly or if he drilled the old one out he didn't get all the crud out
 
thanks for the replies. I have had ther sensor put in from a local specialist. What he told me was, that the new sensor he has put in works fine, the connector is fine, and contacts are clean. It is possibly the wiring before the sensor and im to see an auto electrian, which im going to see tomorrow. The mechanic seemed quite confident in what se was saying and didnt want to fault his work, but will get a second opinion tomorrow, and see if old sensor was drilled out properly. I dont see how the wiring could mess up...??
 
Tariq there isn't many mechanics I don't know in Bradford - who did the work? And to be honest there are no 'specialists' in this area. Period.

Unless someone has been splicing and dicing the wiring, he's talking crap.
 
Tariq have a look at this thread

Thanks for info fahad, im booked in at ds autos in shipley tomorrow morning, hopefully he should be able to sort it, he mentioned that sensor may hav not be put in right. Let you know the outcome
 
Yep that's my concern. Sensor only needs to be set incorrectly by a few mm and it won't read the movement correctly. Also if the old sensor has left bits in there, that will cause problems.
 
had my brothers Civic timing belt done at DS auto's. He seems like a good mechanic. My mate is getting his clutch done from him too.
He's an ex Honda technician.
Tariq I would question the person who installed the sensor and make sure he has done it correctly.
 
Im sick of these xmas lights on ma dash, hope I can solve all my problemz tomorrow morning, Be ther 8.30am sharp, planning to go down to Birmingham for the weekend in the afternoon. i
 
Went down to DS Autos, they advised me that the bearing has possibly been put in wrong way, and there is no Pulser, which sends a signal to the ABS Sensor. Unfortunately he was too busy to deal with it today, but I've got it booked for next wednesday. Hopefully he should be able to solve it.
 
Have you had the bearing changed on it mate? The bearing is part of the sealed hub so it can't really go in the wrong way. As I've said, it's either an incorrectly seated sensor or some rubbish left in there from the old one.. You sure the guy even changed the correct sensor?
 
I seen him take the sensor off, and it he said that the sensor was fitted ok. He took of the middle nut on the hub, knocked the nut out, and then from the back showed me the inner ring. On the drivers side it is all smooth, whereas on the passenger side, there are some ridges there (which is what he was describing to be the pulser). On his diagnostics guide (which is what he was following), he was advised to checker the pulser, and then the ABS pump. He said it is very less like to be the ABS pump.

From what I can remember, he a Snap On diagnostics machine, and the code was 12. (12 indicating front o/s sensor)

Anyhow, the bearing is still the same, car drives fine, but just the lights on the dash. He spent 2 hours and only charged me £10 for diagnosing, but said he needed more time to open the bearing, which means I may have to cough up for new bearings on drivers side. Any ideas on cost?


Im off to birmingham this aft, he advised that the car should be fine no problems, I will take it easy with it.
 
The diagnostics reported Front O/s sensor. I seen it, it is the new one. so it was defo replaced.
 
OK for some reason I thought we were talking about the rear sensor..

Well the lights on the dash are on because there is a problem. Have you had it diagnosed again after changing the sensor, and I'm ***uming you have and its still telling you that the problem is with the same sensor on the front o/s?

Was it a genuine new Honda sensor that was fitted? Not sure if the pulser can develop a fault, it's just ridges on the inside of the hub (that's how the sensor gets it readings on wheel movement)

Yes it was freshly diagnosed this morning by this Honda specialist. He had the Snap On diagnostic machine. He tried switching the lights off, but when he took it for a test drive, the came back on again.
So then when he took the wheel off to look at the pulser behind the hub, he couldnt see one there. So he took off the other front wheel to compare. Then after comparing both front hubs, you can clearly see that there are no ridges on the Drivers side, just smooth chrome type surface, whereas the passenger side you can see the grooves. After seeing this the mechanic made the judgement that the bearings may have been put on wrong way around, with the pulser on the outside, rather than inside.
 
The browb ridges are on the passenger side. Its the drivers side that has a smooth shiny side and no grooves, in place of where the grooves should be.

I tried to explain as best as i can....
 
common mistake when fitting wheel bearings this. you need to be certain you ensure the encoder side is inserted the correct way and that you are carefull not to damage it. annother common problem is with the speed sensors seising into the hub. any swarf left in the cavity may damage the new sensor. you allso have to be extra carefull when drilling as touching the bearing with the drill bit will render it useless. good old backstreet garages eh
 
Aye, they're keeping you guys in business ;)
 
had a similar story with a taxi accord not so long ago. some mate of his worked on his car and diagnosed both front wheel speed sensors were faulty. car came to us with the instruction to fit them, he orderd the parts. the n/s seemd ok, however the o/s sensor wiring was wrapped in insulation tape and removing it i found a poor attemp at re-connecting the wire! on re-fit there was still a fault code. o/s REAR! i dont know what his mate used but he got the diagnosis wrong and cost the bloke more money than nessisary. on inspection, all the split pins were brand new on the o/s/f suspention where the broken speed sensor wire was. the same garage must have stretched or snapped the sensor wire when removing the suspention and attemted to patch it back together. moral of the story, get this sort of work done at a reputabe garage.
 
What happened on my car (much to my embarrassment) was that I didn't remove all of the swarf after drilling out the old sensor, which quickly destroyed the sensing ring on the bearing. New bearing was about £90 ( pattern) £120 ish for OEM :blush: .
 
Its been a week since i owned the car, and already soo much headache. I need to get the car back to a1 condition. Its going in on wednesday to ds autos http://www.ds-autoservices.co.uk. They seemed quite competent, but all garages are out to do you ova...

If any one knows of a better garage to go to around bradford area, im all ears...
 
If you want local try Hepworth Honda at Huddersfield. I've never had a problem with them and the mechanics are more then happy to have a chat with you
If you want to go further then try Holdcroft Honda in Stoke.
 
Tariq I know a few but the worst thing you can do is switch between garages and waste money. Just let one of them own the problem. Stick with the one you're going to and listen to the advice Adam gave you. It's quite possible the bearing was put in the wrong way round.
 
Thanks for the advice. Fahad i think ur right, stick to one garage, just dropped my car off this morning, told him to diagnose all faults. They are friendly and seem to know what they are doing.
 
Got my car back from d s autos yesterday, all sorted!! It was the bearing, the cranks that fitted the bearing forced it in at a slight angle, and somehow managed to either renove the pulser of the bearing, or the wrong bearing was put in.

Anyways the mechanic had been fighting to get the old bearing out, had to use a 20ton press to get it out, but after installtion of a new bearing im all good and all lights have gone off!!

Such a stress since i bought the car... Now i can move on to getting my plate on, HIDs, and tints....
 
Great result, and well done DS Autos. Just goes to show that not all non Honda garages are incompetent ;)

Start enjoying the car now mate.
