That is the way some of the older TPMS systems worked. The theory is if one tire has less air in it it's circumference is different thus it turns at a different speed.

I wasn't asking if the pads and shoes were in good working order, I was asking how worn they are and how adjusted they are. When you come to a complete stop and one of the drum brakes is loose all of the other wheels will have stopped turning before it.

A really bad bearing would cause the wheel to move when you stomp the brake while not moving. Causing the wheel speed sensor to sense a motion.

 

TC light also illuminates when certain codes are set as pending. Yes this can happen without a MIL.

 

My First post to the forum.......Today I changed my plugs, (side note: they definitely needing replacing) but I forgot to plug in that sensor on the air filter housing before starting and of course I get this service traction warning....plugged it back in ,started it back up..all seems well except I have that service engine light staying on now, Does that mean it needs to be cleared and that's all ? never had it come on (except when starting)

Good to be here, handy forum, used it many times for research already!

Thanks, MIke

 

Try disconnecting the NEGATIVE (-) post on the battery for a 10-15 minute period. If all is well, it should clear and reset it.

 

If it was mine, I would pull the codes 1st just to make sure the CEL is related to leaving that wire unplugged. (should be a MAF related code number)
Then you can clear it as whopper suggested.

 

Sometimes it takes 40 cold starts. You may also have gotten a B or C code that is also related to the MAF being disconnected.

Thanks , I will do the battery disconnect..I need to get a code reader..

 

If you have a smart phone, one of the Bluetooth code readers works well - amazon has them for ~$15/20 - the one I have works well, and is a whole lot cheaper and comprehensive than the Innova units I have.

I don't see mine listed as such, but this one looks similar -

 

I went out the next morning to disconnect the battery to clear the code?...but decided to start her up and check, just in case...well the eng check light was off.....
