2004 Toyota Tacoma Q&A

2004 Toyota Tacoma Question: Engine light consistently on. Rat chewed wires. Electronic control module scan.

Wires replaced.ECM cleared and reset. New air/fuel ratio sensor installed. 60k tune up done. 4 new fuel injectors installed. Toyota dealerstill stumped. A month and $2,000 has gone by since the rat bit my taco. Dealer is now consulting with the national techies. Ever heard of anything remotely like this? -
Answer 1
what is the code for the light staying on -
Comment 1
I don't have that info. I'll see if I can find out from the dealer, however, you would think that their knowing that would have directed them to the problem. So far codes have detected: chewed wires, fuel sensor, and fuel injectors in that order. -
Answer 2
yes, rats like to chew on wires -
Comment 1
Especially the new soy-based ones they're making these days; seriously! -
Answer 3
They may be stumped because the rats didn't tell them about ALL of the wires they chewed. AND I would never offer a rat a bite of my taco! If rodents and wires are involved , it will require patience , and yes yours is not the only situation like that unfortunatly. -
