I find a pattern which can make Engine Check light on and off.

Drive 3 or 4 trips. The time between each trip is about 20 minutes, and then the light is on.
However, if I have a trip per day, 3 days later, the light will be off, and after it if I keep drive a trip per day, the light will be never on.

The difference here I think is the engine temperature. Is the O2 sensor bad or other reason?

 

P0133 is Primary Heated O2 Sensor (Sensor 1) Circuit Slow Response
If you have good connections at the O2 sensor and at the PCM and no loose terminals, then replace Primary O2 sensor with OEM Honda or Denso brand.

 

Thanks! I am going to replace the sensor. I am wondering why the sensor works well if I drive the car one trip per day.

 

The O2 sensor was replaced. The P0133 error code has not come back for a week.
I recalled the first time the problem happened 8 years ago. I went to a Honda Dealer in Chicago. The technician told me the computer was broken after checked. And told me the cost would be more than $2000. What a shame for the them.
