Question about 2004 Toyota Prius

1 Answer

Hybrid battery Drove 5 miles home, put 04 Prius in garage. The next morning started and backed out of garage and when went forward noticed engine was running faster than usual and was acting like automatic transmission that was low on oil and was slipping. Checked screen symbol and the Hybrid battery was down to one red line at the bottom of the battery. After driving a few blocks the battery built up to normal. This same thing happened when I was in a traffic back up for a few minutes. My miles per gallon has remained good. Please reply. Buzz E

The first thing that I would check is the weight of oil in the engine crankcase. If you put the wrong weight oil in the engine, you can expect your Prius to do bizaare things. What is printed on the oil fill cap is the ONLY oil that will work properly. If you do have the wrong weight oil, it will puddle in the intake manifold, under the throttle body, You will have to remove the air intake hose and manually open the throttle plate to see the oil puddle. This is an unfortunatly common occurance.

Guages when crazy. Now won't even try to start.


You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)

It sounds like you have some **** in the gas tank that is being drawn to the pickup blocking it.
Have seen this and because it seems so random, it can drive ya nuts.

You might carry a coffee can with you and pull the line from the fuel rail when this happens stick it in the can and just have someone turn the key on for a few seconds.
Beware though, it comes out with force.

Also possible is a failed fuel pressure regulator.
Those aren't expensive and . . . well, not very good either.
