I have a 2005 Prius with 131k miles. The check engine light came on. I had my mechanic check for codes, he had 3different scanners. There were no codes posted. Next day light went off. It has been off for a week. Now it has returned.
View 5 RepliesMy 2005 Prius was working quite fine until few days ago when the dash lit up with ABS, Check Engine, red triangle, ((!)), and the red car symbol on MFD. Additionally, the hybrid battery fan now comes on once in a while. Mileage on car is 164K; changed the 12v and hybrid batteries at about 153K. Running it through codes scanners, the following codes were read off it:
* B1421 (Solar Circuit malfunction, passenger side. Also, AC malfunction [although on the car, the AC still seems to work fine])
* P3000 (Hybrid control fault, and cruise control error)
*C2318 (Low voltage error-power supply malfunction)
I have checked 12V status using the diagnostic mode this morning and found it to be 12.0V (although 2 days ago when I checked it was 11.8V.)
I have not used the car since as I wouldn't want it park up by the roadside. I'm scarred to think its the hybrid battery again... For now, the car still moves well. What should I check to confirm real cause(s) of all these?
I have a 2008 Prius that I purchased used last year. It has just shy of 139,000 miles on it. Recently the check engine light came on, and I dropped by AutoZone to have them pull the codes. They are as follows:
C1241
P1121
P3193
I haven't been able to find a full explanation of the codes online, so I need to know what they mean, how much it would cost to fix, and how urgent the repair is. I will be going on a 5 1/2 hour road trip next week, so I want to make sure I'm not going to break my car (or myself!) by doing so with the engine light on.
My check engine light comes on intermittently, fuel consumption normal. I have not had any noticeable performance issues. I took it to O'Rielly's for a scan but they could not establish a connection to get a readout. Is there a special scan tool needed? The on board Lan Monitor shows EMV codes below, are they meaningful in any way?

Just last week I bought a 2007 prius from a local dealership in Houston. The check engine light recently turned on and had it checked out by an auto parts store. The codes they read were the p1116 and p1121 (issues with the coolant valve). I know it would cost much to replace the valve, and I am not wanting to pay that much, especially since i just bought the car. I'd also be willing to fix it myself if i had some guide or step by step instructions...
View 3 RepliesAlright, so I was driving along and everything was fine, I had no error lights and the car was running perfectly. I accidentally went over a lip of this parking lot a little too fast and all of a sudden the check engine light came on!!! I took it to Jiffy Lube and the codes I got were : c1253, c1311, p0011, and p0012. Is my car safe to drive tomarrow? Are these super expensive to fix? Could they have been set off from the curb?
View 2 RepliesMy '05 Prius check engine light has been on for a while now, at first it would turn on for a while then turn off but now it is staying on. I took it to AutoZone and they ran a diagnostic and it returned the codes P1121, P1123, P1150, P1116.
View 1 RepliesI've had a 2005 Prius for almost 2 year and 50,000 miles now and had no problems. Recently I decided to do an inverter recall and them some "necessary" maintenance (TB, transaxle fluid, etc). How I have an intermittent CEL, P1112 (Intake air temp sensor) coming on every other day. Before I thought Autozone had another DTC detected (1121 It had something to do with a coolant stacked too high?)
What are the most common check engine light (CEL) or DTC codes and how to deal with them?
The car was misfiring and the check engine light codes were all sensor coils were bad. Lexus told me that it was coil6 bad and they fixed it. I should have had no problems, I got a whole 2 miles and I misfired and engine light back on. I drove for a while and light went off and then misfired again. Before I bring it back in I was looking for some insight. I can't understand how it wasn't fixed right the first time but I don't want to go back and get a few thousand bill either. Could fixing one coil cause another to go bad.
View 1 RepliesI have a 2002 Prius that needs work. The red triangle, PS, and check engine light are all on. It has these codes:
P3100 - 175 (HV ECU internal error. Motor Inverter Current Sensor Malfunction)
p3125 - 287 (Motor Inverter Finv. Inverter Internal Short)
c1259 (HV System Regenerative Malfunction)
I suspect the inverter or even worse the MG2 has burnt windings.
BTW the "infamous" inverter pump seems to be working. I can hear it and see the fluid in the reservoir move.
I suspect it is more a symptom than a problem and will disappear when the real problem is fixed.
Just tried to leave for work and my check engine light came on. Luckily I just got a scangauge and the error codes are P0441 and P0445. I checked online and for regular Prius is says it could be the fuel system, fuel cap, etc. I'm scared to drive it now and wonder if I should call Toyota Care to tow my car to service.
View 6 RepliesMy 2004 Cadillac CTS 3.6L started running rough, check engine light flashed on and off. Codes P0300 and P0303. The car has about 119000 miles. Could this just be the plugs? The car has been running fine up to today.
View 2 RepliesMy prius has 172k miles on it, yesterday i got the dreaded red triangle and check engine light along with the temp indicator on the navi screen. I pulled over immediately. after sitting for a bit, the lights went away except for check engine. I checked the engine compartment and felt no real heat anywhere. Coolant reservoir was full i drove a few more miles as i was taking a customer to the airport (i work for uber) and they came on again.
After sitting for a few again they went away and i continued on to the airport. on the way back home, about 40 miles or so later, it happened again. again i sat for a few and it went away and i took it to the dealership in my town. they have always been really cool there (an anomaly i know) I never before used dealerships for anything before owning a prius) and he pulled the code for me and it showed POAOF failure to start. that had actually never happened, but was told that it doesn't necessarily mean the car wouldn't start, it can happen while running.
He cleared the code, as i had recently changed the 12v battery and after reading a bit here i know it can cause some weird stuff so i was hopeful that would do the trick. so today i went out and worked again. Drove probably around 50 miles or so and on the way home it happened again. Back to the dealership. This time they put the main tech on it and he also got the code P0121 indicating the throttle position sensor. He took apart the throttle body and tested it and said it was showing not enough ohms or something like that (I know jack all about electrical) and that the throttle body was bad and would need replacing, also saying there was oil in the intake and it would need to be cleaned.
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
I have an 05 F-150 Lariat 5.4 and it has been going haywire today. While driving if I hit a hard bump the power will cut off (radio, a/c) and even sometimes the truck. Check engine light came on and I pulled codes P2160 & P0506. Also, when it completely cuts off and I start it back up it says "engine in failsafe mode".
View 1 RepliesMy wife's 2005 has a Christmas tree of lights on lighting up the dash including the brake, the large triangle exclamation point, and the check engine light. The MFD says problem and has the little red car with an exclamation point on it. The car will only go in neutral and the ice will not engage. I borrowed a scanner (older Actron) from a friend and it shows no codes. I replaced the 12v battery with an Optima a couple of days ago (after having similar issues) and drove about 60 miles with no troubles. I rebuilt the traction battery back in July and have put about 10,000 miles on it. Should any OBDII scanner pull the codes?
View 19 RepliesI use a scangauge to monitor the traction battery in my 2001 prius. Today when I started the car to come home, the alarm triangle came on, but the scangauge shows no codes found. The car ran fine and got me home, but what the alarm is about.
View 11 RepliesThis morning I tried to drive my 2008 Prius and the "check engine" light quickly blinked and the dashboard didn't light up. The monitor did turn on and I could hear the engine running. The monitor showed that the hybrid battery was almost full. While trying to go in reverse, the camera did not work. We just had an oil change done. The 12V battery was replaced almost 2 years ago. The car has almost 150K on it. I also tried tightening the gas cap. It's obviously winter and it snowed last night (in case that might be a factor).
View 19 RepliesI have a 2007 Prius which today, for the first time ever, refused to start. I pressed the Start button and all that happened is the "check engine" and "airbag" lights came on (dimly), and the green LED on the "P" (park) button began blinking. I pressed the "Start" button again but nothing I can do will change this. The car is sitting in my garage now, in this condition. I turned the dome light on briefly and it was very dim, so I suspect the 12v battery is dead. Only problem is, to access it requires opening the back hatchback door, which won't open without 12v power. Meanwhile the tiny bit of power that's left is being drained by the system in it's half-on condition (above). If I could get to the battery I could connect an external charger to charge it up enough to start it but I can't. What should do?
View 19 RepliesI was wondering if this seems reasonable. I just bought a used 2008 Prius top trim package with 107,00 miles on it this last month. The first day I owned it a check engine light was triggered. The guy I bought it from hooked it up to his computer and cleared it to then try to trigger it again. This happened when I first turned on the car. I started backing and then it turned on. I didn't know what caused it as we couldn't trigger the response again. It's been a few weeks now and 1 trip to the shop for some repairs. There have been no problems what-so-ever since then and my Prius just started getting close to the 50 MPH as advertised after a tune up.
Today when I'm driving, as the seller did mention before could happen, the right headlight turned off. As he had told me before, just turning the lights off and turning them back on will get it working again. I did this and as soon as I did the check engine light came on. I go back to the night I originally had it happen and I was probably in the process of turning on my lights.
2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!
