Problem with 2001 Accord Emission Readiness Codes

I had trouble getting car through PA Emission inspection. After disconnecting battery in April computer had only reset 5 of the 7 codes causing the check engine light to flash 5 times before going off.


Air fuel ratio sensor monitor code and EGR Monitor code were NOT set.

OPD2 gave NO codes on Modis

Coolant temp was 58 deg C. and as I remember it should have been 62 deg C.

Wasted 3 days and 1/2 tank of gas driving car in various driving conditions (OEM Drive Cycle) - steady throttle, 50 - 70 mph and coming to complete stop, etc but still only 5 of 7 readiness codes etc, etc, - while contributing to the Earth's GreenHouse gases.

The Problem:

With Throttle plate "Closed" the TPS voltage was 0.63 volts and the HONDA spec calls for 0.50 volts.

The Fix:

Removed throttle body and tamper proof screws; Reset TPS voltage to 0.51 volts. Reinstalled Throttle body body and road tested.

O2 monitor ran almost immediately and the EGR was reset the following day.
