    p2021 code came up, what do I do?

    P2021 - Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 2) came up and car won't start. Where is this and is it something I can do to fix it, or do I need to replace it. subaru's are new to me and I don't know to much about them. so anything will help.

    It's one of the Tumble Generator Valve sensors. It's basically a TPS sensor. Check to make sure it's still plugged in. There is one on each side of the motor. The TGV's are the lower half of the intake manifold right before the cylinder heads. You obviously would have to replace the sensor if defective.
