Occasionally (almost every day) my JTS throws up two Lambda errors:
P0134 Lambda Sensor Bank 1 (Pre Cat)
P0154 Lambda Sensor Bank 2 Slow Response (Pre Cat)
both with "Fault Symptom: No Signal"
As clearing them makes them go away for a while, I am assuming I have a dodgy connection somewhere, and they are not failing per say. Its also funny that its always the same two, and both do so at the same time!
So before I go on a wild goose chase, where should I start looking for connection problems ?
