po449-- Evaporative Emission Control System Vent Valve/Solenoid Circuit, causes---Vacuum leaks, damaged hoses or improper routing
- EVAP system - Check fuel cap, canister, valves or components
- Faulty purge or vent solenoids
- Check connector and wiring
- Fuel saturated vapor canister
- Failed EVAP vent solenoid, the best thing to do is have a certified mechanic check it out.for proper diagnosis Good-Day!
Could be one of the control actuators. The actuators are moved by small electric motors and one of them could be sticking.
It would be tough to give suggestions without knowing where the noise is coming from.
Does the noise happen if you turn the key on, then off, without starting the engine ? Or does it matter if the control is on defrost or heat ?
Could be a few things. Most likely APP (accelerator pedal position) sensor. Take it to auto zone for a free diagnostic scan. They'll tell you for sure. If it's the APP sensor, rock auto (dot) com has the cheapest ones I've seen short of yankin one out of a salvage yard. About $70 shipped last time I checked. Could also be the ECU. That's bad. You're talking several hundred then instead of $70. Regardless, get the scan done at auto zone first to find the issue and get the code. If it's the app sensor, buy the thing and install it yourself. Simple as hell. Just disconnect the wiring harness running between the gas pedal and the under dash &remove the two bolts holding it down. Put the new one in place and reverse the removal process and you're done. The ECU is much more complicated. Too much to type here. You may be best off leaving that one (if that's what it is) to the pros, depending on your experience level. No matter what, I wouldn't recommend driving it (except to auto zone and back) because it can suddenly decrease your speed while driving, potentially causing an accident. Good luck!
ABS is not how good something stops. Its a safety feature that kicks in when wheels lock up.
Stopping good is a matter of Brake pads, and brake rotors having a good surface. new pads wont work well on anything that is not a fresh machine job or new. Also make sure pads are not rusted in caliper brackets. Common when not greased upon install and winter conditions.
Stopping good also requires the hydraulic units to be working correctly. Make sure all caliper slides are working and not rusted in place which is very common for poor brake issues.
good luck
Resetting the ABS light is usually done by erasing the code. Using a scan tool is best. Sometimes disconnecting battery might work, and sometimes radios become not operable when done this way. Needing a radio reset code may be needed if this happens. See dealer or owners manual if this happens. It explains everything.
Some vehicles it will go out when you fix the issue and just drive the car around completely repaired.
Good luck
There are actually 4 blend door actuators.One for the heater, one for the a.c., one for the external air and one for the recirculating air. I checked in with a mechanic and he stated that there are two different part numbers but either one will work for any of the four. My experience was initailly with only one and it was suggested that i use all of the different systems and sure enough all four needed to be replaced. There are three actuators behind the glove box. 1. is to the very far upper right on the passenger side near the inside of the dash and the other is to the left behind the glove box on the passenger side more towards where the radio is, the third one being situated above the 2nd one. The 4th one is located above the gas pedal towards the center of the dash.n All four are not difficult to replace its just a matter of getting to them and working without being able to actuallty see them. sense of touch is crucial. =o)
General instructions for door panel removal; Door panels are attached to the door frame with clips such as the one above. The ribbed, screw-like part of the clips are inserted into holes in the door frame around the perimeter of the sides and bottom of the panel
Auto Repair Mechanics How to Remove Car Door Panel
The video shows details of door panel removal. First locate all the screws on the door panel, usually at the door handle and door rest. Look for any hidden screws that may be covered with small plastic caps.
After all screws are removed, the side and bottom clips need to be popped out of the door frame. You can purchase a set of trim tools to pop the clips, or you can use flat blade screw drivers and a flat putty knife to pop the clips out. Sometimes the clips break, but they are replaceable. Once the sides and bottom are loose, the top of the panel is loosened by lifting up on the panel, disengaging the panel from the top track on the door frame. Be careful of wiring connectors, which will have to be disconnected to completely remove the panel.
