You'll just end up wasting money and frustrating yourself further.Trying to get the wagon to pass Oregon DEQ which requires all monitors to be ready. or how much Chinesium is in it.Īgain, I would test them both. That is a super old school method, but it's cheap, fairly easy to set up and super accurate! You don't have to worry about how many years your gauge has been sitting on the shelf. You can also test your MAP sensor using a either a very accurate low pressure vacuum gauge, or you can do what I usually do and build yourself a $5 slackline manometer. If the AF sensor responds in the correct way, there is nothing wrong with it. You can spray some gasoline or carb cleaner in the intake to force the mixture rich.ĭo these tests. You can pull a vacuum hose to force the mixture lean. You can and should test your AF sensor first. Throwing parts at the problem is almost always a mistake. I wouldn't jump to the conclusion that you need to replace your MAP or AF sensor. ) + perfect fuel mixtures and pollution controls ( chemistry )
Modern cars are a giant mixture of mechanical moving parts ( physics ) + metallurgy( material science ) + electronics + computers / networking (Programming and I.T. When I work on Modern cars I use all of it! I have a background in Automechanics, Electronics, Programming and General I.T. We have to know so much about computers (and lucky that I am in IT field.) Man, fixing cars is not just mechanical anymore. Hopefully I will end up able to do the reflash myself () for $75 subscription.
Fuel system monitor not ready pro#
Then, I just bought a Autel maxisys pro J2534 box off ebay for cheap.
Fuel system monitor not ready update#
According to the dealer when I called them, that would be $300 even if there is no update / need for the reflash. A local indy shop told me to take it to the dealer to do a reflash first, before dealing with the emission cycle and the tranny jerking. Local dealer service adviser told me if the TCU is inside the valve body, a reflash is needed. I was told that if the tranny is replaced, a reflash might be needed. That did not help.Īnother thing I was looking at was the ECU TCU reflash. I disconnected the battery and shorted out the positive and negative cables few days ago to hope it will clear up some memory. All other monitors were set except the fuel one.
I have driven the car for over 300 miles. I will change out the MAP and the AF ratio sensor this weekend. Please Log in or Create an account to join the conversation. I don't see it trying to correct by adding or subtracting fuel. The lambda sure doesn't seem to know about it.
We only really need to see the O2 lambda, it looked nearly perfect at 0.999:1 the entire time. If you want you could trade out the bottom display ( O2 Sensor current for Intake Air Temp ). Have you tried driving the car? Maybe the fuel monitor won't set until it tests the fuel system under real life engine load conditions.Įverything that I saw in the video looked pretty normal.
