i continue to get this code even though the coolant and engine temp are good. i changed the coolant over flow tank. could the system be reading the temp there? the code comes up only in the afternoon when the ambient temp is above 20ºC/ 50ºF. Mornings are below 0ºC/20ºF and no check engine light. car seems to run well. i clear the code and all is good fro awhile and then the check engine light comes on with the same code. any ideas on solutions. i have the bentley book for the 2001 and don't see any trouble shooting guide for the code.
thanks in advance. mhg
