The check engine light on my 2000 Honda CRV came on. A local garage
(Atlanta, Georgia) read the code p0131 - bad oxygen sensor - and reset
the car's computer. The check engine light then blinked on and off,
rather than stay completely on as before. I had them order the oxygen
sensor in order to replace the faulty one. On the drive home, the check
engine light went off and has stayed off.
Should I still replace the sensor, or wait until I get a check engine
light with code p0131?
