Help! ABS light DTC 4-2

Hi all,
So I got my left ball joint replaced and the guy broke my front left ABS sensor. I know about car parts but not repair procedure. The service manual only have rubber boot replacement procedure and I wasnt sure if he was supposed to remove the ABS sensor before he started banging away at the knuckle. I shorted the ABS service pin and found DTC 4-2.

Anyways. I'm looking for left front ABS sensor. I can't find anything on EBAY. does anyone know if ABS sensors from other honda/acura cars will fit in the 96 TL? I'd like to broaden my search term.

If you could point me to a source it'd be much appreciated. Also, I'm thinking about doing things DIY now. I dont trust a lot of mechanics. They either charge too much or dont know what they're doing.

Cheers!

Will the 2.5L sensors work on a 3.2L?

Thank you

Suggest contacting some of the ebay vendors offering aftermarket wheel speed sensors. They may be able to help.

Second try calling your local salvage yards. car-part.com can give you an idea where there are 3.2TL's, then place a call to desk and ask for your part.

good luck

Thanks Texashonda

I found some 96 2.5TL on ebay but not sure if they'll fit.

I called the dealer and they wanted $220 (CAD) for the 3.2TL part !!.
sick! thats my last resort.

Did some research. There seems to be after market abs sensor parts for TL 99 above.. but not 96TL. Will continue to look

on Car-part.com, I couldnt really search for the item. neither "ABS sensor" nor "wheel sensors" were on the drop down item.. the only thing is the knuckle that comes with abs.

By the way does anyone know the ohm value you should read when you connect a multimeter to the front abs sensor?

Hi, For anyone who cares the 2.5 TL abs wheel sensor does not work on the 3.2 TL.

I will post ohm reading for the 3.2 TL front sensors soon. Planning to check it tonight

A working front sensor should read about 780 ohms. My broken one is open circuit.
I'm planning to remove it tomorrow

Use car-part.com to locate a donor vehicle and call yard to ask for wheel sensor.

It may be possible to splice a donor sensor to your harness. looks tricky.

good luck

Actually it probably isnt. If I do some good soldering its very possible.

Hmm. good point. Thanks again TexasHonda

Epic success!

Well, I called about 20 yards asking for ABS sensor. None of them are willing to take them off the spindle and risk breaking them PLUS apparently on the 3.2TL taking it off is a pain in the ass so no one was willing to do it and sell it to me.

Seeing that this was the case. I cut the harness RIGHT at the sensor and found that the sensor itself isnt broken, but the wiring on the harness was. Given that I work in a university lab and have access to all the soldering equipment I spent sometime re-soldering the whole wiring. and it WORKED.

so now ABS is totally working again thank you ACURA engineers for DTC trouble shooting code..

And thanks TexasHonda for the suggestion!

Cheers!

Glad to hear of your success.

Did you simply trim back the harness and sensor to expose the conductor and splice? I seem to remember a ground shield around the center conductor also. Was that spliced? Was shrink-wrap used to recover?

thanks

Hi TexasHonda,

First thing I had to do was to determine where the wire broke. I did a "binary search" i.e cut the harness wire in half. test for short, then cut the failed half in half again and continue. The fail point was a twisted wire.

There was no center conductor and ground (i.e it not like a coaxial cable). Its simply two high gauge wires (which explains why they are so prone to breaking).
I simply reused what I could of the original wire and solder and and join where I cut with similar gauge wires, wrap couple of layers of electrical tape and stabled with even more electrical tape.

Finally I made sure the ohm reading was around 800 ohms when measured across the two pins of the sensor connector, then plug and play.

worked like a charm.

Cheers

Thanks for explanation. Good to know they can be spliced relatively simply.

regards
