![]() But you’d have to fix it by the time the smog test is needed again, in two years. If this is the first time this has happened, I think there’s probably a second way to get around all this. EVAP Monitor Not Ready is more or less saying your vehicle doesn’t detect fuel vapor because the EVAP monitor is not ready for a self-test. What is the drive cycle on 1997 Toyota Camry to complete the EVAP monitor. It monitors fuel vapor leaks and prevents fuel vapor from polluting the atmosphere. P0450 Toyota Camry 1997The Evaporative Emission System vapor pressure sensor. The monitors are also known as Emissions Monitors. The purpose of readiness monitors is to self-test the car’s emission control systems. The EVAP system monitor needs very specific conditions to set and is the most difficult to get to set so dont. This tutorial will explain in detail what the readiness monitors are. Start a new Toyota Camry Solara question. They provide insight to the car’s self-diagnostics. But if you phone you may get someone willing to help. The Evaporative Emission Control System (EVAP) system is a crucial system. OBD2 Readiness Monitors are simple yet powerful self check routines. Unfortunately, if the website is still like it was when I was going through a similar problem about a year ago, the BAR website isn’t very well organized, almost to the point where it appears the BAR is trying to obfuscate the issues and how the owner can resolve them for some reason. If all else fails, you might try phoning up the Calif BAR and see if they can offer a solution. Toyota Camry P0442 Code Symptoms There are rarely any symptoms related to the P0442 code. P0442 indicates your Camry has a minor EVAP leak. Different code numbers represent the leak size. Release pressure in tank by removing gas cap. When the Toyota Camry’s computer detects that the EVAP system has a leak, it will throw the P0442 code. Cold soak for 8 hours (ECT is between 40f and 95f, IAT is between 40f and 95f, ECT and IAT are within 13f from each other.) -Fuel is between 1/2 and 3/4 tank. All you want to do is get the car smogged, but no clear way to get past this hurdle. This is the drive cycle that Toyota gave me: -Warm up engine. ![]() Maybe get your charging system and battery tested.Īll this sound pretty frustrating. ![]() A bad/loose fuse to the ECM, bad battery connections, battery on the fritz that drops out on bumps, etc. And maybe the cat monitor is just the one that takes the longest to complete. The ECM would randomly keep starting over with the monitors. It’s also possible the ECM is losing power for some reason, temporarily. Visit during a day/time when they aren’t very busy. They probably deal with this quit a bit, and they are the experts. I think if I had this problem I’d visit a Toyota dealership shop and ask them what driving pattern is needed for that monitor to complete. You may just have to repeat that protocol a few times, and keep checking on your own. Do you own an OBD II tool? They aren’t super expensive and are reported to be easy to use. You may have to experiment a bit to get it to set.
