Thread: All Error Messages But One

I am getting all the error messages one normally gets when the throttle position sensor would fail, except REDUCED ENGINE POWER. (and the engine power does not change.) SERVICE STABILITY CONTROL. SERVICE BRAKE SYSTEM, SERVICE TRACTION CONTROL. ABS, brake, and TCS idiot lights on. Everything clears if I restart the car.

Is this the ABS module, or something else harder to replace but less expensive?

First, scan for codes. It could be a broken sensor wire, a bad wheel hub, poor connection at the abs module, or the module itself. I personally had 2 breaks in the left front wiring and a poor connection at the module. Pop off the connector and spray both ends with electrical contact cleaner. I thought I had another broken wire the third time all the lights came on, but the last time was the connection at the module. You could try that first if you don't have a scan tool.

Took it to a shop, they say it's the ABS solenoid valve. I can't find an exact match for this part anywhere on the Internet. Things with similar names have priced from $275-700. Some parts are sellable, some are discontinued.

Does anyone else have experience with this part? Does this sound realistic?

Thanks for the answer. I refuse to be without ABS in Florida, where it rains year round, but I even less want to be without brakes.

Took it to a shop, they replaced the harnesses, which did absolutely nothing. They gave me a printout which says there's a discrepancy in the speed sensors which is causing the error message, but there's no history showing which wheel is doing it. They say I have to drive the car longer. I have driven it for as long as an hour. I think the problem is, every time I turn the engine off, the errors clear.

Are the speed sensors in the hubs? If they are, I probably have narrowed the problem down. I changed the front hubs last year.

Sure enough, one of the new hubs.
