Prius (2004-09) :: DTC P0A9B Hybrid Battery Temperature Sensor Circuit
Dec 6, 2010
Had a customer car with DTC P0A9B in 2005 Prius with 170k miles so out of warranty. Car would code immediately when turned on but would drive fine, 45MPG average etc.
Dealer had told customer solution is to "replace entire HV battery assembly". .
Customer battery ECU was 89890-47070.
Got a slightly newer battery ECU 89890-47071 from a hybrid recycler in Denver. Replaced only the battery ECU, cleared codes, no more problems. Car now running great.

I have these two codes:
P0A37 - Generator temperature sensor circuit range/performance
P0A2B - Drive motor "A" temperature sensor circuit range/performance

Need solving a P0172 code I had. I just pulled out the MAF sensor and cleaned it with a MAF Sensor Cleaner (at most auto parts stores). Worked like a charm and the code went away and the gas smell is gone too.
Now I have a new code - P0712. I have been extensively searching the web and cannot find any good information on how to resolve this issue - "P0712 Transmission Fluid Temperature Sensor Circuit Low Input" ...
I checked the fluid level and it is fine.
I have a 2005 Camry, 2.2 liter, 4 cylinders...

P0073 Ambient air temperature sensor circuit high. Preliminary inspection, right outside mirror badly damaged/broken. Guess where the sensor is?

Check engine light is on, this is the code that came up when checked at OReillys, "P0113 Intake Air temperature sensor 1 Circuit high input". Earlier took it to repair shop, he did not give the code, some sensor needs to be changed (don't know if he came up with same code). He had erased the code but it came back on within minutes. Wanted to check if there is any cheaper way to fix this. This is a windstar van.

2011 6.7... My truck is throwing code P2033 Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor. What is the part number for that sensor?

I've owned my 2012 F-250, 6.7L for less than a week and it has a check engine light. The local dealer can't see me for a week, and I need to leave town next week.
I went to AutoZone to have the codes checked and this is what they came back with:
P2033
Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
P2031
Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
Can I drive on these codes, or should I park the truck until Ford can see me?

My concern: The hybrid battery, or the monitor really, has never, ever, not once, shown an all-bars charge. It is almost always at one bar down, and will drop below that but never goes above. My brother has a Gen I and his battery shows all bars from time to time. Not mine.

My hybrid battery has been running low the past few days. This has never happened before, but it has been around 90 degrees out during the same few days. I noticed it this morning as I left for work. It was down to two bars when pulling out of the garage. I was getting pretty nervous, but at least the ICE was charging it. Although, it never fully charged the system, as I live pretty close to work. On the way home, I tried to drive around for a mile or so to see if I could get the battery fully charged.. The best I could do was four bars. Is this typical of the hybrid system in warm weather? Should I be worried about it? Also, the system has a fan, why doesn't it come on if the hybrid battery is so temp sensitive?

I recently purchased a used 2007 prius. The car has not been driven for some time. I won it in an auction from a used/wreaked car lot and am in the process of fixing it up. I need to know if it is possible to charge the hybrid battery when the car is idling or will this only discharge the hybrid battery and if so, is there any way to charge the hybrid battery other than driving the car?

i have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.

I changed a bad cell in my hybrid battery (only one cell was bad) and put everything back together and it wont start. I've double checked all connections, fuses, everything I took off. I put the orange plug back in, fiddled with it, pushed it in more. It's got a brand new 12V battery and I dropped it off at autozone to get it charged up as well. Here are some pics and what it's showing .....

I have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.
I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.
The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.

I'm pulling a P0403 EGR circuit fault on a 2004 v6 Escape.
Last night I changed out the EGR solenoid. Cleared the code and drove around for a while, got on the highway and cruised for a few miles and everything seemed fine. Turn the car off and back on and the code showed up again.
My next step will be to check the electrical connection to the solenoid. I don't do a lot of auto repair.
With my multimeter I will check for 12 volts. But from what I understand I can not check ground as the PCM sends ground to the solenoid to activate it. How should I check the electrical connections to the EGR solenoid?

A year and a half ago, I had the hybrid battery warning lights come on and had it towed to the dealer. After given the option of replacing the battery for $4300, I took it home and did a single cell replacement (all cells ~8V, one at 6.6V which I replaced), which seemed to be all good until yesterday. Back with the warning lights and blower fan, I jumped to the conclusion that I have a similar situation, removed the battery and all cells are 8.04V +/- .05V except for 1 cell at 7.92. I am not convinced that this cell is really the culprit.

Just got a 2008. The Hybrid Battery Status indicator on the display is usually yellow. it will sometimes switch to blue. I assumed that yellow was the correct color but after reading some posts here it seems that they should be blue.

Can we check the health of the hybrid battery like you can the 12V. I encountered an issue where the hybrid battery had difficulty getting a "full" charge. It would frequently be in the three to two bar range which got my attention. I did learn that there is not a way to check the hybrid battery. I also have not encountered the problem since crossing the great divide on the way back ....

My 2005 prius will not start. We had some body work done to it after a deer ran into me. They did a small amount of welding and had disconnected both batteries. Now the car will not start. It can be put in auxiliary mode but if you try to start it with your foot on the brake, it flashes some lights for a few seconds and then goes dead. Is the hybrid battery too low to start the car? It was pretty low. before the batteries were disconnected. Or did they possibly do something wrong when they disconnected the hybrid battery? Final question would be do they have to do some reprogramming after disconnecting the hybrid battery?

In comparing the battery drains on a Camry hybrid versus a Prius Gen II hybrid I discovered both have three stages of battery drains after a door open incident. On a Gen II Right after the door is open the drain was 1.37 amps.

My 2007 Prius has been with me for 3 months now. I am really happy with its performance, especially its fuel consumption rate.
I would like to check the state of the hybrid battery and maintenance it if necessary. How could I get this done?

I replaced the hybrid battery in my 2005 Prius today & when I disconnected the 12v battery the wrench arced & I assume that I blew a fuse. I have looked, but have not found anything. I hope I am missing something obvious.
