Secondary air system monitor12/29/2023 ![]() I would bet within about 30 minutes or less the obvious problems can be ruled in or out. Take a few minutes, roll up your sleeves and open the hood. The problem is "Generation Text" want immediate gratification and a software solution for EVERYTHING. If anyone bothers to read all the links I posted almost all the issues are covered and it will not take the OP long to figure out what is going on. If the SAP runs and there are no problems with the car, the SAP Readiness Monitors should turn to Ready/Pass/Clear state. Unless the CA temps are over 100F day in and day out, the SAP should run for at least 30-45 seconds on cold start if not longer. The SAP system is fairly simple and it is the first and easiest Readiness Monitor to turn to a Ready/Pass/Clear state. ![]() There is really NO NEED to try to use any software, it is really exists, to "force" a Readiness Monitor. The SMOG tests are fairly comprehensive and you cannot easily get around the SMOG test by trying to reflash the DME or spoof the Readiness Monitors. This is the dumbest thread or at least is heading toward the dumbest answers/suggestions.įirst California has the strictest Emission requirements in the world. The OP needs to realize that it is not that hard to get the SAP system working properly. I am no expert on CA SMOG rules, but I thought that the seller was responsible for getting the vehicles SMOGed?īut at this point it is what it is. The OP purchased a 15+ year old car and seems to be perplexed that there are problems with it? Realistic Expectations need to be considered. What I just do not get so many people are buy 10+ year old cars that someone is selling for a REASON and they seem to expect to not need to do any basic maintenance on them. BUT lazy O2 sensors clearly can cause the SAP Monitors to not turn to a a Ready/Pass/Clear state. O2 sensors lazy: This is not as common as the above items #1 & #2. ![]() Airflow control: Kombi valve stuck, vacuum hoses deteriorated, vacuum control valve damaged or connected wrong, small check valve installed backwards.ģ. This tends to be pretty easy to narrow down.Ģ. Airflow or lack of: pump does not run, impeller on pump spins, pump does not put out enough airflow. Suggest you readjust your expectations and focus on fixing the car correctly and also make sure the SES/CEL/MIL functions properly as it sound like is has been disabled.Įverything you need to know about the SAP systems here:īTW, the Readers Digest version is there are 3 basic areas where a MAFless SAP system can fail.ġ. Your year car does not have a MAF based SAP system, it is a simpler system, but has a vacuum based Kombi valve. It should be in a Ready/Pass/Clear state after the first cold start. The SAP Readiness Monitor is the fastest and easiest one to turn to a Ready/Pass/Clear state. The SES/CEL/MIL NEEDS to be functional for it to pass ANY state SMOG/Emissions test if the inspection is halfway coherent and doing his job. If there were codes, they were there for a reason AND it sounds like the SES/CEL/MIL has been disabled based on what you are saying about the car. Next, you state there were 11 trouble codes but no light and the codes were in accurate, this is crap. Not sure where you are getting this information. (Very unlikely the dealer won't create or "find" a problem because of the monitor.)įirst there is no software that can "force" the SAP monitor to a Ready/Pass/Clear state. And then, taking that diagnostic report to a state ref smog shop. The only way you can get an exemption for another code is taking your car to the dealer and getting a diagnostic report confirming that there is nothing wrong with your car and the monitor is inaccurate. I only have a limited amount of time to take care of this smog check.Īnd as of May, 2015 in California, vehicles 2000 and newer may only have the EVAP monitor incomplete. Some people have said the ambient air temperature should be pretty cold to get the monitor to complete but here in Southern California, the lows don't get under 70 and there is no cold weather in the forecast. ![]() I highly doubt anything is wrong with the Sec Air Sys, nor do I care if it is. Reset all the codes because none of them were accurate so I can pass California smog, after a couple drive cycles, all the codes are complete except for the secondary air system. Just bought a 2002 330ci which had 11 trouble codes when I checked it but no CEL. So, instead of messing around with the entire secondary air system finding crusty vacuum lines, replacing MAFs, replacing secondary air valves which are perfectly fine, and other things, which software can force the secondary air system monitor ready from incomplete? I know there is a program that does it, just don't know what one does. Hello everyone, I realize there are tons of threads regarding the secondary air system monitor but none which have addressed my question.
