I keep getting an 84-1 sensor logic failure error on my 05 RL. The triangle with the ! in it is on solid and there as soon as I start the car. Once I get into D (drive) and go less than a 1/4 mile the ' check VSA system' light comes on. I am not getting any other codes. The car drives fine and I assume that the VSA system is inop because of this error.

My question is does anyone know what sensor this is? Is there a seperate sensor on the VSA or is there a sensor that also manages other parts. Seems odd to me that there are no DTC codes listed either. I can erase the code but the orange triangle with the ! in it won't go off.

Any ideas would be appreciated. Thanks
