APP Sensor
Over the past 2 weeks my 98 has thrown codes related to the APP system and "circuit performance". It's happened 3 times. This comes along with a check engine light, reduced engine power, and service traction control system message. Once I turn the car off and on it's fine. The code is listed as history and if I clear it, the check engine light goes off. Since it's done it more that once, I'm beginning to think it's not just a typical C5 quirk. Does anyone know of anything I can do to help or what might be causing this? If it has to go to the dealer to get the sensor replaced, does anyone know what sort of cash I'm looking at? Mucho appreciation for any help you could provide. Thanks!
