Car loses power when air conditioning is on. Indicator shows that BATTERY IS VERY LOW
SOURCE: 2004 toyota prius hybrid power loss on uphill grades
Since you did not mention that there are any warning lights on at the dash, I must advise you of the following: Prius vehicles are VERY PICKY when it comes to the proper weight of oil. That being said, and if you have the wrong weight oil in it, expect problems. Easy way to check this: Take off the tube going to the throttle body at the front of the engine. Open the throttle plate & look down into the intake...Do you see any oil laying there, in puddles? If so, you def have incorrect oil in the engine. This will NOT det a DTC code, and it WILL give you your condition.
SOURCE: It stalls sporadically when air condition is on on
Your ivs is sticking, when you a/c is on it will kick up the idle to keep it from stalling,It just has some carbon in it but its best to replace it,Thanks, I hope this helps you
SOURCE: 1996 Toyota Celica GT: car loses power and stalls out.
Check alternator voltage at back of alternator ( big wire ), if you have no less then 13.5 volt's, alternator is ok, check for blown alternator fuse or break at wire from back of alternator to starter then to battery, could be a bad fuse link at starter.
SOURCE: 2008 Toyota Prius instrument display does not come
you should take the care to the dealer while it's still under warranty, since electronic stuffs are very expensive now a day
SOURCE: stalls when accelerating in wet weather
I dont use this word much but im Assumeing that YOUR mechanic scanned the computer and checked the coolant sensor or other possible causes,Ive ran across this many times before so bare with me,Have your mechanic try a known good Airflow meter and dont forget to check the main airboot for rips,cracks or tears in the seams,gotta inspect all the areas where it is accordianed for flexibility,another one is moisture penetrating into the distributor cap,got more if ya need them hope this helped let me know have a good day Darrell
