Separate names with a comma.
The DTC should give you freeze frame data on what happened when the code was thrown. I haven't had to do this, but I hear you click on the...
When you bought the car, did you get a Carfax report? At 99K miles, some of this stuff may have been done before you bought it, and it would show...
And keep in mind many oil change places routinely over-fill the Prius. If you put in the rated capacity, the level is slightly high on the...
Yes, it certainly could be an issue. If you're not in the habit of checking the dipstick every couple of fill-ups, now's the time to start. It's...
A 2 mpg increase is fairly common after replacing an old 12V, I hear.
A new battery should read around 12.8V with no load, and should stay above 12V under accessory load. An old battery will take energy (in the...
Look into the filler tube of the inverter reservoir with the car in IG-ON mode (push button twice, foot off brake). Can you see the coolant...
Without diagnostic test codes (DTCs), we're simply guessing. A zero-cost option is to try getting a free scanner read at your local auto parts...
Yes. Connect to the hybrid battery ECU and that will give you block voltages (pairs of modules). P0A80 is telling you there's too much...
In your OP, you say all the indicators are lit up. Does this include the MIL (check engine light)? If so, there are DTCs and you're not reading...
When the oil got low enough to trigger the warning, some damage to the engine resulted. That warning is intended to let you know the engine is...
You may get P1121 again. If you do, replace the three-way valve at your convenience--it's generally not a critical item. Worst case it'll affect...
I'm not sure how to contact corporate, but if you can document the errors in this thread, like a Toyota-trained mechanic telling you the CHRS tank...
The plastic grille on the top right of the rear seat is an intake for cooling the hybrid battery and it's unlikely smoke came out of it. There...
If you're not getting coolant into the passenger cabin (liquid, vapor or odor), you probably don't have a heater core leak. If it were colder...
It looks like the two devices share the 7.5 Amp ACC fuse and ACC relay. Check the fuse carefully, with a meter, not just visually. When the fuse...
On the tail lights, if the license plate lights and side indicators are working that means the switch, fuse, and relay are okay. About the only...
You reported the voltage in ACC mode. What are the voltages in IG-ON (more load--turn on A/C fan and headlights) and "Ready" modes?
I suppose you can set up an example where less tread would give better traction. Climbing shoes and dragster tires are slick. But on a passenger...
