im not sure on location, but to test if this is the problem there are a few ways , at the fuel pump itself check for voltage . also while cranking the vehicle check the fuel pressure.(the second one is a bit technical)
You would go to a mechanic and ask what the problem is.
wiring problem...easy to fix..no mechanic needed...
Problem is likely the oxygen sensor (located on each of the exhaust manifolds). These are a common problem and can be replace by the average diy shade tree mechanic. 10 minutes each with a cool engine.
It is on because the computer has detected a problem with the emissions system. Take it to a trusted mechanic for a scan and diagnostic of the problem.
I am having the same problem. I know for sure there is one on the transmission but according to my mechanic there is another in the instrument cluster at the speedometer. Can seem to find any info on the speedometer sensor.
Usually a problem in the emission control system-have vehicle scanned to determine the problem
Having the same problem, spoke to Toyota mechanic friend of mine and said its most likely the AC relay.
Go to your nearest garage and tell the mechanic the problem and he will do it for a certain amount of money
