I have a 2004 Tundra, V6 5VZ-FE engine, 2wd, automatic. 43,000 miles. A very straightforward truck. 4 months prior to this writing my truck took a surge from a lightning strike. Evidence of this is seen on the aerial wherein much of the black coating is fried off. I was there when it happened. The truck did not start afterwards. It would crank but would not turn over. There were no blown fuses. I replaced the crankshaft sensor, no dice. Finally I replaced the ignitor. Easily found in the engine compartment mounted on the right wheel well. That fixed it. Started right up. Has run great ever since. Note: I found the Ignitor on ebay for $40. Toyota dealer wanted almost $450.
However I have some lingering problems. The engine will not pass emissions inspection because the computer at the inspection station says that the Evaporative System & the Catalytic Converter are not registering as ready to test. An OBD scan by their OBD tool & my own tool indicates the same thing but does not currently show any DTCs. I did have a DTC for the AF Sensor upstream from the front Cat. I replaced that. I also replaced the Oxygen Sensor downstream from the rear Cat just to be thorough. Dealer purchase with identical Toyota numbers. That fixed the DTC but I still have a not ready indication for the Cat & Evap.
Also on the dashboard I have lit & flashing Indicator lights for the Airbag System & the Antilock Brakes, ABS. I changed my front brakes, they were due anyway. The light for the ABS still flashes intermittently, at irregular intervals & is not too annoying. The Airbag light flashes nonstop so I covered it with a piece of tape. Wonderful.
I am inclined to think that I have problem in my primary computer, ECP. I have had the battery cables on & off numerous time since the lightning hit. I also just put in a new battery. As well, directly after the lightning surge I replaced the old computer with an identical one that I bought used. (ebay also) At the time I figured the surge went directly to the computer. It did not work in the truck. I immediately reinstalled the original computer & its been back in ever since. Before I start troubleshooting these individual indicators, Cat, Evap, ABS & Airbag, perhaps I should examine the primary computer.
My question is this. Should my original computer be recalibrated? Is that something that can be done? As well, can the replacement computer be reconfigured to my truck?
Truck runs great. Just can't pass inspection.
I have no interest in taking it to Toyota. Too far, too expensive & I need my truck everyday.
You might be rolling the dice with just about everything electronic on the truck from now on :cry:. Modern vehicles use electronics in every corner. It all has surge protection, but mostly from things like spark plug noise etc. The lightning hit produces a severe EMP and it goes everywhere on the harness. I hate to say this, but depending on your finances, it might be a good excuse to grab an 07 with 5.7 V8.
