That was the throttle that did that, not the purge valve. The same thing happened when my throttle died. It threw like three throttle-related codes and went into low power mode while I was on the highway, no less.My throttle body came today and is getting put on tonight. So that should take care of the CEL for the throttle position not learned, now for the purge CEL. So I should get a purge valve solenoid and hopefully it fixes the issue. So is there a particular reason that would send it in to safety mode because that's a new one for me
The way I understand it, if a major engine control is not available or not functioning properly and the computer can't communicate with it or get proper readings from it, the computer defaults to a default set of fixed parameters that SHOULD keep the engine running by default regardless of the climate or conditions the engine is operating in. If everything is working properly then the computer adjusts engine parameters constantly to match demands and conditions in order to get the best performance and economy out of it. Limp home mode is there just to get the car to its destination, and economy and performance are left to suffer as a result.
