I'm sure this must be on here somewhere but none of the links I looked at had the codes I got:
C1230 Rear Speed Sensor Circuit Fault
C1102 Acceleration Switch Circuit Fault

Now that I have them I'm not sure what to do next...

Thanx for any help you can offer.

 

I have the same question. I know this is an old thread, but maybe by me responding, i'll get some attention to this question. I took my car in to read the ABS codes and they came back with a C1155 and a C 1102. Sounds from what i've learned about the C1155 code, all you have to do is replace it. Maybe the same deal with the C1102?

Is there any reason these codes may be going off? Any other potential problems or fixes i need to make other than simply replacing them? Also, if anyone has any information about where to find these sensors, how much they cost and how to change them, i would greatly appreciate it.

Thank you!

 

I don't remember how I found out but I just had to replace the sensor over the rear "pumpkin".

 

On the C-1155, it's a left front wheel ABS speed sensor circuit failure code.

Could be a number of things, like corroded or damaged electrical connector pins/sockets, damaged wiring, bad sensor, or maybe the sensor or tone ring are fouled with debris, or rust.

Put it right & see what happens with the C-1102 code, for the ABS acceleration switch circuit failure. I believe it's mounted on the drivers side frame rail, back below where the divers seat is, close to the fuel filter. Check it's wiring & electrical connector pins/sockets for corrosion, ect, or it could be a faulty sensor.

Did this problem come about after some event, like an off road session, or driving on the beach in salt water, ect?????

 

No, it didn't come from anything in particular. I have mostly been commuting every day on the highway about 45 mins each way. I have noticed some issues with the breaks as of late but it seems that the codes are not related to the problems, which seem mechanical...

 

What is the rear "pumpkin?" Where did you get the sensor, how much was it and was it difficult to replace?
