Also, there is the possibility that your scan tool will miss the code. Mine is intermittent sometimes. There are actually two computers responding to the error code query from the scan tool. One is the ECU and the other is the TCM. So some scan tools will miss the TCM response, which is the bad one. But a proper scan tool implementation will always get the TCM response...
A poor scan tool will only expect a single response to an OBD query or only have enough memory to store one response. However, the OBD protocol allows multiple responses and they can come back to back very quickly.
I've driven the car for over 3 months since that time and it has been well above 2500 RPM. The AutoTap OBD II scan (
http://www.autotap.com/) and is an excellent scan tool and I seriously doubt it will miss codes, as it never has in the past and especially now with the new revised code. Keep in mind that the P0888 is the pesty one and my scan tool would never remove that one and it always reported it. That one disappeared after the down time on the car.Don't know what to tell you, but that's my experience. Hope this helps.
