Help with P0153 code

[cchw]

Hi. I'm new to the forums here. Thanks to all who contribute to this site. The CEL recently turned on my 1996 Camry V6. The CanOB2 car reader I recently purchased showed the code P1053 when I scanned the car. This code refers to:

O2 Sensor Circuit Slow Response (Bank2, Sensor1)

I then proceeded to inspect the sensor per the documentation I have on the Camry. Using an ohmmeter, I checked the resistance between the terminals +B and HT. It was reading around 14 ohms which is within spec. Since it seemed OK, I went ahead and reset the CEL.

Was there a glitch in the computer that triggered this event or do you folks think there's a real issue here? Has anyone experienced this? The CEL hasn't came back on again but it's only been a day.

Thanks in advance.

The O2 sensor may be slow to respond to changes in A/F mixture as a result of sensor deterioration.

The computer tests the sensor under certain established engine conditions and until 2 trips are made, until then the CEL may not come on.

To add to ^. My Dad's CEL went on for his '96 for an O2, I reset it, then took 2 months till it came back on. I replaced the sensor the 2nd time the CEL went on.
