Smog Marathon

#1

I have a Honda Accord 2001, 5 speed, 4 cylinder, 2.3L. In order to conduct the smog test, some parameters have to be set. My Oxygen sensor and EGR parameters do not set. I have been to three smog shops including the dealer and they all tell me the same thing: “drive the car.” Heck! I have been driving this car for over a month and still have the same problem. According to the Accord bible there is a way to reset these parameters. The procedure is as follows:

1. Start the car in neutral

2. Rev it up to 3000 rpm

3. Keep it there until the radiator fan kicks in

4. Idle for 5 seconds (skip this step for EGR)

5. Drive the car for at least two minutes (more than 10 seconds for the EGR) at a steady speed between 50-62mph

6. Release the throttle completely for at least 5 seconds.



I have followed and executed this procedure many times, the problem does not go away. Now my DMV license tags are about to expire. I am in a bind, HELP!

If that procedure does actually “reset” the parameters, then you need to stop doing it. That is your problem. You need to drive the car to establish the trim paramters and then take it in w/o resetting.

The sensors that provide the needed information might be bad…More likely, their connectors are at fault…if the sensors and wiring check out, the ECM itself can be at fault and it will NEVER allow an emissions test…
