Recapping: The State Of California will give a pass on a smog check to any OBD vehicle with an incomplete evap monitor. Didn't know at the time, or I'd have done it that day. So, I could have smogged it right after the secondary air system passed its monitor. The car he has owned for years (A Chevy) still has an incomplete evap monitor. According to him, some GM cars (like Malibus) take forever to set evap. So, they plugged it into their computer, and that was that.Īn important note for my fellows in California: I was talking to the guy smogging the car, and apparently, in the State Of California, you can / will pass smog if your evap monitor is incomplete. Apparently in California, 2000 model year and newer cars aren't put on the dyno because it makes the ABS system (and traction control, where applicable) go haywire. It passed with flying colors no dyno needed. I took the car to the smog checker today. Re: Evap and secondary air monitors incomplete. It's not the greatest news, but at least I am now sure that the secondary air system is running its tests. I haven't looked at the front valve, but I plan on taking a good look at the system tomorrow. I saw no indication of trouble inside the rubber hose to the rear check valve when I changed the O2 sensor. I saw no indication on the air pipes that exhaust has been backing up into them. It hasn't been cold enough for water to freeze, so if the pump has failed, it has failed for some other reason. As to whether it is now, well, we shall see.įrom everything I have been reading, these air pumps are notorious for having water get into them from exhaust going the wrong way up the air injection check valves. I do know that when I first met the car, it was started with the hood up and I heard the air pump working. Since it was almost dark when I read the codes, and since the car was hot, I figured there was no point in checking things tonight. That is a code for the secondary air system. Re: evap and secondary air monitors incomplete.update 1īoth tests are still incomplete, but as of this evening, after a day full of driving, my code reader tells me I have a p0410 pending. Unfortunately, that won't make the smog test computer happy unless the monitors are complete. The fact that it hasn't set any codes tells me the system is working properly. I would prefer to read from those who have direct experience as to what you did to get the tests completed. really like this car, I'd really like to get it legal. Incomplete monitor tests will DEFINITELY be grounds for failure, no matter what. It's a Cali car, so in order to get the registration all done and legal, it must pass a smog test. My questions are:ġ) is there a time frame or number of starts (especially cold starts) required to get them to set? If so, what is the number?Ģ) is there a procedure that will, just by doing it, set those monitors? Still neither the evap and secondary air system tests will complete. My assumption is it doesn't take all that long to set an evap code with the gas cap off, so to some degree, the car "knows" the evap system is working properly, otherwise, I'd have pending evap codes.Īll the other monitors are set, and there are no codes, real or pending. I don't recall if they had been complete before the amnesia hit. The problem now is the evap and secondary air monitor tests are stubbornly refusing to come up as complete. Because of this, I pulled the negative battery cable to give the PCM amnesia. Sadly, attempting to remove the codes with my code reader worked only with the pending code. The new sensor and wiring repair fixed the initial issues. It had set codes p0113 (IAT), p0113 pending, and p0135 (O2 sensor heater). My 2000 Malibu had a bad O2 sensor and a wiring issue with the IAT sensor as well. Evap and secondary air monitors incomplete. ![]()
