ECM/PCM Data

NOTE:

The "operating values" listed are approximate and may vary depending on the environment and the individual vehicle.
Unless noted otherwise, "at idle speed" means idling with the engine completely warmed up, A/T in park or neutral, M/T in neutral position, and the A/C and all accessories turned off.

You can retrieve data from the ECM/PCM by connecting the OBD II scan tool or the Honda PGM Tester to the data link connector (DLC). The items listed in the table below conform to SAE recommended practice. The Honda PGM Tester also reads data beyond that recommended by SAE to help you find the causes of intermittent problems.
