- 2003 Park Avenue Ultra
2003 Ultra been having this recurring problem. ABS and TRAC light come on intermittently. They reset each time you turn the car off then may stay off 100 miles or more then come on again at any time. I'm getting a C1232 code on my scammer, shorted or open circuit on my left front speed sensor. Also had another code in the past that wasn't there this time something about variable speed on my left front wheel unable to determine wheel speed something like that. So anyway I figure the left front speed sensor is bad or possibly there could be a broken wire somewhere going to the sensor not sure. But unfortunately as far as I can tell the speed sensor is not replaceable you have to replace the whole Hub. And then should probably have the front end realigned, which was just recently done by the previous owner, the car drives great.. But the Hub shows no signs of being bad and I don't really want to replace it if it isn't. On the other hand winter is coming and I don't like the idea of no ABS brakes and no Traction control on slick roads. Any ideas on what I might try short of Hub replacement. I've done the Hubs before and it is not a problem to do them just wondering if I'm missing something and might be able to fix short of that. Thanks.
