ABS Acceleration sensor?

My ABS light is on. Told the dealership to scan it when I got my free hitch installed. They came back with 2 problems: One, front driver speed sensor. Easy fix. Other one: Acceleration sensor. They said that part isn't available any more. I can't find an acceleration sensor in the FSM. I find an acceleration switch, but can't really tell where it's located. It appears off the ECU, but the diagram isn't the greatest. Is that what they are talking about? Where exactly are they located?

Also, is it the same part on the 5.2L as the 4.0L?

It's listed in the parts catalog as "accelerator switch", P/N 56006315AB. It's showing as still available - or at least, *not* showing as discontinued - at my go-to Mopar parts discounters. Looks like it'll run you about $75 online.

Yes, it's the same part for both engine sizes.

As to location, I believe it's somewhere under the carpet. You won't find it in the FSM, it's only covered in the separate ABS diagnostic manual. I have the 1993 ABS manual, but I don't think that will help you because they'd changed the ABS supplier by 1995.

EDIT - plug that part number into eBay and there are loads of them for sale.

Great. Thanks. I don't have a parts catalog, so I couldn't find that. I can get one for $17 on eBay, used but work. So not bad. Rear seat? Under the carpet? Any ideas?

I just checked my 1993 ABS manual, and the G switch (same thing as the accelerator switch) is located under the rear seat. That matches with the general diagram in the 94-96 parts catalog (the specific location of the switch is not pointed out in the catalog).

At the risk of telling you something you already know, the switch should be installed with the arrow on the casing pointing towards the front of the Jeep.

Thanks. I assumed that the arrow went that way. Good to have confirmation
