Yesterday I got a power loss light. I stopped and checked my wiring and all of my vacuum connections and hoses in the turbo system. Everything seemed fine so I did a code check and came up with a code 22. When I restarted the engine the power loss light wasn't on anymore. It didn't return when I drove the car. I know that the sensor is good because this code has come and gone in the past. Has anybody had this experience or do you know why this is happening.
