Prius (2004-09) :: 2006, CEL And Error Code P0505 Came On
I was driving home the other day and my CEL came on... I checked the gas cap and waited a few days to see if it cleared. When it didn't clear I had the codes read and it came back with 3 instances of P0505.
View 2 RepliesPrius (2004-09) :: ICE Won't Shut Down - Code P0505
I recently borrowed an engine code scanner after my check engine light went on and got a P0505 code on my 2004 Prius with 185,000 miles and started to fix things. I replaced the PCV and spark plugs as well as the air filter. It ran fine, but decided to also clean the MAF using CRC MAF cleaner and also clean the throttle body and butterfly using CRC Throttle Body cleaner. I also carefully washed out the engine compartment using Gunk Foamy.
I seem to have put it all back together, but now the ICE won't shut down, even when warm, and actually wants to rev beyond what seems to be needed. I got another scanner and got some stuff that I honestly don't understand. It said 2 codes then gave me P0505 followed by:
Mil On
Monitor 0 inc
6 ready
misfire
fuel
comp
catalyst
evap
O2 sensor
Prius (2004-09) :: P0505 Diagnostic Code, ICE Would Not Shut At All
I had our '04, 149,000 miles in for PA state inspection and emissions test as well as to be looked at because of a P0505 diagnostic code. The symptom of the diagnostic code was that the ICE would not shut at all. The past few months I simply cleared the code (ScanGauge) and things were immediately back to normal until the check engine light came on again.
Anyway, in response to the P0505 today they replaced the air filter (I checked, it is installed correctly), checked for vacuum leaks (all okay) and cleaned the throttle body. My wife picked up the car this afternoon from the repair shop (independent, but mechanic trained by Toyota for Prius). Upon arriving home she said I needed to drive it because it is acting very strange. We drove it this evening and indeed it is acting strange. A number of times the engine revved up to 2800-3000 rpm when my foot was off the gas, e.g. slowing to go around a corner or even when sitting at a traffic light. The SOC was normal (blue bars), not high or low. It was also interesting, because even though the transmission was in D, the car was not pulling to go forward, e.g. at the traffic light-- in D, engine revving, but car just sitting there as though it was idling or ICE off.
The ICE would shut down and go to battery mode appropriately. However I noticed that the mpg would not go about about 110 when backing off the gas going down a long hill at around 50 mph (engine warm, battery normal charge). Normally this would bump it up to around 200.
This latter symptom of mpg not going about 110 is a bit subjective and we only drove around 20 miles this evening, but I know we did not experience the engine revving before the car being serviced today.
Prius (2004-09) :: Getting P0505 Code - Idling Roughly
I have a 2004 Prius with 196k on it. Over the past 3 months, I have had the P0505 CEL come on about 3 times. After looking over everything and not noticing it running differently, I have cleared the code and kept going. The CEL stays off for a 3-4 weeks, then comes back on.
Yesterday, the light came on and was accompanied by a rougher idle. I checked the code and the only one shown is P0505 reads as Idle Air Control System. I removed the airbox and cleaned the MAF sensor with MAF spray and cleaned the throttle body valve with throttle body cleaner spray. They were both dirty, but didn't seem too bad.
Prius (2004-09) :: CEL Code P0505 - Idle Air Control Malfunction
My check engine light has come on twice now and I'm getting a p0505 code, idle air control malfunction. It seems as though there could be a couple causes for this. All my hoses seem tight, so the cheap fix seems out of the question. What could the other causes be, and more importantly, about how much for a shop to fix it. I have a 2006 with 155,000 miles on it.

Just picked up a 2005 with 146k and full Toyota service history, although seems a steering recall was not done. Will run it to the dealer today to check. I need to decide a.s.a.p. if I am keeping the car or not (I know the seller, he will take it back)
Anyway to cut a long story short, two questions.
1) Car had P3190 and P0420 when I got it. Seller reset, drove home and within 5 minutes on the road the CEL was back on. Checked the codes at home and see only a P0420. Much to worry about? Seems this might be big (Cat) or small (O2). Car getting great mileage - 60mpg at 60mph and it seems to be running great. Should I worry or forget about it? Note I am in Florida with no inspections.
Prius (2004-09) :: 2005 - Pulled Over Error Code P0420
So I bought a used 2005 Prius back in August it had 88,000 miles on it and was out of warranty. But I had a full inspection on it and the car was in great shape. Well, after a few months of driving, I got the P0420 error. I took it into my mechanic who cleared the code and told me to call him if it came back on. It came back on, then I cleared it myself, and it came back on again. So it was confirmed that I had a bad catalytic converter.

Prius (2004-09) :: 2005 - Inverter Dead / No Error Code?
My 2005 died in the middle of the road a few days go. Was just rolling along fine then suddenly out of a stop light, the car stalled and would no longer go back into P, D, or R while the battery still seemed to be working. So had it towed to the dealership to be checked.
View 5 RepliesPrius (Gen 2) :: Code P0505 - MPG Dropped To 31
The engine light went on and I took it to my mechanics who is good on everything except Hybrid system.
Immediate after the lights on, I filled gas and the mpg dropped to 31, soon back to 37 on a hot day 85 degree. At red light, I feel the engine still running, not very smoothly. But the next day, it back to normal, mpg also back to 48 something.
My friend has a 2005 with 140K also got the same code. His mpg dropped to 40 and feel that engine power is lower now.
I would like to know if this is a common problem, what's the most probable cause, and if there are many possibilities, what's the best way to approach.
Here is problem area by OBD-II:
Engine and ECT
Hybrid Control
ABS/VSC/TRC
Air Conditioner
Immobiliser
Avalon 2005-12 :: CEL Error Code P0440 Error Code / Charcoal Canister Replacement
So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.
Prius (Gen 2) :: CEL On - ScanGauge Reports Diagnostic Code P0505
I made three ten mile trips this evening. On the first trip the "engine" light came on. This is the first time I have seen this light (2004 @ 134,000 miles). ScanGauge reports diagnostic code P0505. The "engine" light remained on through all three trips. Also, I was not able to get the ICE to shut down and run only on battery at all, even though the battery was on the upper level of charge and the engine was warm. There were long stretches where I normally run on battery at around 35 mph. I'm supposing there is a connection.

My 2004 Rubicon has been having some idling issues. It idles kind of rough (+- 200 RPM) and is hard to start. I tried to start it recently and after 4 cranks, it started then the CEL came on, and has been on ever since. I have recently moved from Washington state to Houston Texas, and the problem starterd here in Texas. I checked the code and am getting a P0505 code. I had a mechanic replace the IAC valve, Checked for vacuum leaks, and cleaned the throttle body. The mechanic says the output from the main computer appears to have burned out, and needs to replace the main computer(for $1000). The mechanic can clear the CEL, but after turning the jeep off then back on it reappears. The mechanic says he verified the computer was the problem by installing a known good computer and it cleared the problem. Does this sound right to you? If my computer is bad, wouldn't my whole operation be affected?
View 4 RepliesPrius (Gen 2) :: Rough Idle And Acceleration After Throttle Body Cleaning - Code P0505
Few weeks ago.....Prius was showing the P0505 code .... Mechanic, ran diagnostics and determined it was dirty TB. Cleaned TB.....cleared the code (inspected PCV...hoses).
When I initially picked it up it was revving very high....so he hooked it back up to the scanner and did some type of "reset" for the idle (this cleared most some computer settings...back-up beep, radio stations, etc...). Everything ran fine for past 3 weeks...
Just last night..... started running rough again. What I noticed this morning ... Started it up and it ran very rough til the auto shutdown after warmup (no warning lights). Then....when I started driving slowly out of the lot...it ran "rough upon acceleration"...... Then fine at cruising speed. Same behavior at every light....rough acceleration.... fine once up to speed. Just started it up again and same behavior.....(does not die...just very rough).
Prius (2004-09) :: HV Error Code P0A80
My car has been fine with no changes besides tires last week, its a 2006 Prius and yesterday I got lights on my dash, went to auto zone for a read out and got an HV error code. I was wondering what is the most affordable route for my car to get repaired. I don't notice any mpg differences and everything still charges and recharges as if the errors don't exist.

View 5 RepliesPrius (2004-09) :: Getting Error Code PO456?
Its a 2009 Prius with about 75K miles on it. I have scangauge on the dash as well as mini-VCI. It is setting PO456 code time after time. I reset it, but it comes back in about 50 mils of driving. Its not the gas cap, I turn it until it clicks every time. Something is wrong with evaporative emissions system, which I wouldn't care about, except it might mask some other fault code that is more serious, as it keeps check eng. light on all the time.

View 2 RepliesPrius (2004-09) :: 2006 - Getting Error Code P0AAC?
Installed Rebuilt Hybrid Battery AND New 12v Yesterday. Worked great until just now. Got the cool Red Triangle and VSC... hooked up to that Cool code machine and got the P0AAC (Hybrid Battery Pack Air Temperature Sensor "A" Circuit).
What is this exactly and what should I do? If it's a simple fix, I'm sure I can do it with my dad ... after all, I did take and reinstall the battery myself. Also, is it going to hurt my car if I drive on it with this issue?
Car is 06 and has 211K miles.
Prius (Gen 2) :: 2004 - Error Code C1310 / Malfunction In HV System
I have a 2004 Prius with 80k miles. Always has been a workhorse. Recently had a bad cell in the HV battery. Battery rebuilt with new cell and now works great.
Now it runs about 20 miles and then displays dash lights of red triangle and small exclamation (brake?) and VSC.
I took it to Advance Auto and their scanner reads C1310 'Malfunction in HV system'.
I actually replaced the entire HV battery again with the battery from my friend's car, and the 12V battery too, but no luck. Same error.
If i disconnect the 12v battery for a while, it will clear the code and the car runs fine for about 20 miles and then dash lights come on again.
Car runs perfectly, over 50mpg even with the dash lit up. What that code is?
