Code 24 and won't fire - any suggestions?

If they were grounded to the intake manifold every injector would be on 100% of the time. I suspect drivability and fuel economy would suffer

It would remove it.
. Reason I thought of it as a test for him is because on my car Im running speed density via maftpro, and the only way to get rid of code 24 is to run a 2.2k ohm resistor between E2 and THA. Take care- Steve
Steve, of course a 2.2K resistor will remove it. That's not a short, it's 2.2K, a resistance value within the range of the stock sensor which is, after all, nothing but a thermistor.
A short would be the input directly connected to E2 and the ecu wouldn't accept that. I don't know much about the MaftPro but that dummied up 2.2K THA input could be a problem if it doesn't represent the climate where you run the car. Since it's a constant though it may not. Depends on how the MaftPro does things.
*Edit*...A quick check shows 2.2K to be around 60-68 degrees F so it's not a problem. It represents what the stock sensor would output at that temp. Hardly what I'd call a short

Well guys, the fellow with the car got it towed somewhere - I suspect to the local Toyota dealership, so I don't get to try my mad diagnostic skillz any more.
I really hope Toyota doesn't ream him too badly.

Heard back from him today. He got it towed to his usual mechanic, turned out to be a defective / dead fuel pump.
