Fuel injectors gone bad, or so they say!

Yes, if you disconnect the 12V battery negative terminal for 5 minutes, that will clear any DTC logged by the engine and hybrid vehicle ECUs.

 

Congratulations!

Uhh... why are you using premium?

 

Premium (that is, octane > 87) really is a complete waste of money in a Prius. If you are concerned about the quality of the additives look for a "Top Tier" fuel seller and buy their regular (octane = 87, or 85 at altitude):
Top Tier Gasoline

 

Does anyone know of a way to turn off the CEL without taking it to someone with the software to do it?

Take it to a auto parts store...AutoZone or Advance Auto...not sure if you have either in your area....they will do it for nothing.

 

For most things, just disconnecting the 12v battery for a few minutes will do it.

The easiest way is to simply unplug the white +12v connector located under the red battery fuse cover (battery positive terminal). You don't need any tools.

Tip: leave the hatch open while this is disconnected!

 

wolfeberg have you thought about cleaning injectors ? i have been able to clean many sets on mine and customers cars.

 

This is not the best idler when cold. My 06 is a bit rough at cold starts as well.H

 

um its not realy a diy thing without the equiptment there is two ways to go about it 1 in car. a high strenth cleaning solution and gas is pumped into the fuel rail with the engine running/fuel pump disconected. 2 (best way imo) remove injectors from car, take to mechanic. they will electronicly pluse the injectors open and closed whilst they sit in a ultrasonic bath containing cleaning fluid. this will back flush the fluid through the injector and the ultra sonic waves vibrate the carbon out into the fluid.

 

Another clueless/corrupt Toyota dealership. I guess where you live you don't have much choice

 

Look at the bright side, you now know a lot more about your dealer than you did before and the knowledge you aquired for free saved you $1144.

One of the few magic solutions in a bottle that actually works is Techron. If you use Top Tier gasoline you probably won't need it, but an occasional dose of Techron won't hurt and it might help. The placebo effect alone will make your engine seem smother

 

Toyota had recently released an updated TSB for Classic no-start problems, which was posted in the Generation 1 forum. The TSB suggests putting throttle cleaner on a cloth and scrubbing the throttle plate and throttle body interior with that cloth, rather than spraying huge volumes of cleaner into the throttle body.

My cleaning process is to remove the air cleaner housing, then use Q-tips moistened in rubbing alcohol, since I believe that "less is more" when it comes to throttle body cleaning. Certainly you do not want to contaminate the mass air flow sensor with any liquid besides MAF sensor cleaner.

 

Just had the same thing happen and was told it had to be bad gas. Paid 1119.00 for four new injectors. It's now two weeks and 1500 miles later and the same thing is happening again. I'm back to the dealer on Monday. What will they tell me this time? Help. Anybody? I bought the car at 31000
All the checks done and the Carfax in order. Only warranty a 100,000 power-train. This isn't covered of course. Can one sue?

 

I've just had this happen. CEL has been on for almost a year. Took the car to the mechanic, they couldn't figure out the problem last May. She recently lost acceleration and had to be towed to the shop. Mechanic called and told me that it would be $990 for 4 new fuel injectors. Should I try cleaning the MAF sensor before replacing them? Get them cleaned first? Just go ahead and replace them myself? And is the new higher grade fuel from Shell close to Top Tier fuels?

 

From what I understand "top tier" refers the supplier and not the grade. There is a list of suppliers who are accredited as top tier that you can google.

Any fuel from a top tier supplier is "top tier".

hope this helps.
