Dad put on a new gas cap OEM with VIN the light came back on but with a code P0113 NEW CODE!. My code reader states that there is a problem still with the evap system. no code yet. It would be nice to have schematics for EVAP SYSTEM.
If there is no evap code how do you know there is a problem with the evap?Does your code reader say evap monitor not ready?Thats normal because you just had the code and cleared so it will reset the monitors and they will have to be reset.If your not needing a smog soon no worries the monitor will reset will you drive over time.So was there a problem with the cap is that why it was replaced?Also the code P0113 is inlet air temp sensor circuit high voltage.Does your code reader display engine live data?If so what does your iat sensor show for temp?
My code reader also has LED's Green Yellow Red and yellow is on which tells me that there is a wire/or solenoid that is faulty. I had just gone through a pile of work on my truck and now I finnally have a green light. Truck code was P0455 I changed the evap canister vent solenoid and right away I have a Green light and now NO PROBLEMS!!!! yah!
Innova model 3030 works well for me but it would be nice to get an on-line scanner. P0113 came back on, so I guess I will replace the sensor
I have noticed that some gas doesn't even smell like gas anymore, some have a turpentine smell to it. Just all depends wher ya go.
Does your scanner read live data?If so what does your inlet air temp sensor read temp wise?Most of the air inlet temp issues i have seen have been the connector or wires to it and not the sensor but anything is possible.
Just looked up your scanner i was right those lights are for your monitors to tell you if there set and your car is ok to take to try to smog it.Its nothing to do with the wiring for your evap system it just means you have to do the drive cycle to set the monitors that arent set.Doesnt look like it will read live engine data.
Smell of gas when driving,not all the time,some times after driving smells of gas coming from engine area,no leak noticed
