I don't know much about cars, so I might get some terms wrong.
My girlfriend drives an '01 Sienna LE and for a couple months the check engine light has been on. When I took the van to O'Reilly's and had them check the computer, it came back with the following error:
P0330: Knock Sensor 2 Circuit (Bank 2)
I've been working with a friend of mine to try and fix it, as he's extremely proficient with cars, but he's also somewhat hard to get a hold of sometimes. Things we've tried:
- Changing the fuses. Not all, but the ECM and a couple others.
- Using an octane booster and a higher grade gasoline (89 as compared to the usual 87).
Light is still on, and he said that now we'll need to take the intake off/apart to get the sensor which is inside near the cylinders. Is there anything else we can try? It's like $130 for a new sensor, plus mechanic fees. We just don't have the money for all of that.
