Honda: Bogus DTC.
Honda says that some 2003 Element models with manual gearboxes (VINs 5J6YH1...3L000001 through 5J6YH1...3L009732) may mistakenly turn on the MIL and store DTC P0420 (catalyst system efficiency below threshold) in PCM memory.
The Japanese carmaker attributes the bogus code to the PCM incorrectly interpreting the signals of certain key sensors. Reprogramming the computer with a new software calibration should turn off the light and prevent a recurrence. You'll find the new software files on Interactive Network CDs produced from June 2003 and later.
