I'm new to this, so thank you in advance. I recently had to replace my alternator and upon doing so, the check engine and trac light came on. In addition, now I cannot roll down any of the passenger windows from the drivers seat. The windows will roll down, just not from the drivers seat. The car is running great, but these lights do not seem to want to turn off. I did get the car checked out at the local auto part store and was given this code P0020. Can someone please help???

 

Howdy... The error is likely from a pulled wire on the Bank2 Oil Controller Valve. It's silver solenoid with two wires. There are two and one is right behind the oil fill cap. The other is down lower and angled slightly. Gently pull on the wires and see if one pulls out. They are on the same side of the engine as the alternator.

As for the door switch, that is normal when the battery is disconnected on Toyotas, Mazda's others....
Go to each none drivers door switch and power the window all the way down holding it down a bit longer than necessary. Then hold the switch in the UP position and power it up, hold it down a few seconds after its up all the way. Do the other two and you're set.

 

On the right side you see three circles. Two are solenoids and one is the camshaft sensor. There is another camshaft sensor further back on the valve cover.

Did you do any work up top?

 

Thank you for the information. I will work on it later on today. I greatly appreciate your help.

 

I was finally able to do what you told me to do. I had to order a new clip, but it was relatively cheap. Once I changed it out, the light came off. I truly appreciate your help. That light was driving me crazy.
