Just got done with my valve job (500 mile ago), and the OH monitor is still blinking on my OBDII reader? Help!   marc olivares (Pugs) Member Username: Pugs Post Number: 182 Registered: 12-2002 Posted on Tuesday, September 16, 2003 - 11:39 pm:    are you O2 sensors good. that test should happen shortly after startup. marc   Matt Olson (Matt) New Member Username: Matt Post Number: 2 Registered: 09-2003 Posted on Wednesday, September 17, 2003 - 06:17 pm:    OS Monitor test happens right away. I'm talking about the OH test for the Oxygen system Heaters. If the O2 sensors were bad, it would give you a fault code. I have no fault codes, but the OH monitor has not completed its test, so I can't emmission test until then.   marc olivares (Pugs) Member Username: Pugs Post Number: 187 Registered: 12-2002 Posted on Wednesday, September 17, 2003 - 09:35 pm:    the heater monitor should also happen right away. and continue to function until the heaters are not needed on the o2 sensor. we are talking about the same system, right? marc
