My toyota highlander with 124k miles has a check engine light and a VSC light on. When i went to scan it there was a P0442 as well as a C1201. Autozone told me the EGR vacuum solenoid went bad. How do i replace it? I checked all the hoses and they all looked fine.
The hoses attach to the solenoid. Replace the solenoid. What difference does it make if the hoses look fine?
Please answer all the questions in the first paragraph, year mileage, trans, etc.
They said a probable fix was to replace the solenoid, but not sure what else. Also i have a 2006 highlander with a v6 engine
If you are going to a dealer, I'm sure they'll find other things to needlessly charge you for. Just replace the solenoid and go from there.
How would i go about doing that though?
I am fairly certain you have to remove the entire intake manifold system to get to it. Thanks, Toyota! Probably best to check some Toyota specific forums on how to get to it.
Roger that
AutoZone should be able to provide you with instructions and a diagram on how to replace the EGR vacuum solenoid, they own the All Data service that Scotty uses when he works on cars.
Try to find an under the hood diagram online, it might be easy to find. It's a completely different vehicle, but I accidentally broke one of the vacuum line connections on that solenoid on my 1999 Ranger when I was pulling off my TPS last year and had to replace it. The parts stores wanted $100 for it, I pulled one at the junkyard for $20. All it took was 2 bolts and it's off.
Apparently there isn't even one of those solenoids in my car, all i had to do was disconnect and reconnect the negative battery terminal as well as tighten the gas cap
