Ok so on our 2005 Montana Non-SV6 the ABS light would go on when driving. After shutting the engine off, the light would go off and come back on when driving it again. Got the Scanner hooked up. First time the scanner showed like 6 different ABS codes. Reset the system, drove around a little till light came on, this time only one code came up. Code C1233 seems like a right front Sensor is out. Any of you had this issue with your van? The sensor is expensive because it comes with a whole hub assembly. Don't want to replace it if it's not the root of the problem. Any of you with same experience?
