My get engine light not on but failed inspection what to do

Hello: Code 420 normally indicates a catalytic converter is operating below 60% efficiency. You need to take your car to another shop and request a COMPLETE diagnosis not a dart board guess.

The problem is with your air flow meter , you need to replace it

Hello. You can do this yourself.

You need to replace the Air-fuel sensor. I would strongly suggest that you purchase and install a Toyota sensor, however. The "aftermarket" sensors do not have the exact same voltage signals, and will not rectify the condition; the light will remain on. We see this quite a bit in our service dept.

We hope that this helps you out.

P0330 Knock Sensor 2 Circuit Malfunction (Bank 2)
Check the resistance of the knock sensor (compare it to factory specs)
The knock sensor is faulty and needs to be replaced.
Check for broken/frayed wires leading to the sensor.
There is a wiring short/fault in the knock sensor circuit
Check timing

Have had similiar problem w. 2002 Highlander.
It happens when the airfilter comparment is touched, moved or opened. The hose attachment comes lose and the engine light comes on. Attached hose to airfilter casing a little tighter and the light will eventually go off. Takes about 2 weeks to go off.
