Prius (2004-09) :: 2005 - Car Went To Limp Mode Then Stopped With P0A0F After Maintenance
Oct 19, 2013
I have a 2005 Prius. After driving home from a 95K routine maintenance inspection, the car (with the display indicating 50% in the gas tank) went to limp mode and then stopped entirely and had to be towed back to the dealer. The codes pulled were
P0A0F (Engine failed to start)
P3000 (Battery control system)
B2799 (Immobilizer Malfunction)
P3190 (Poor engine power).
The techs concluded that the car was simply out of gas and the display incorrectly showed I still had gas in the tank due to a broken sender in the tank. They also said they added 1 1/2 gallons, and the car ran fine again.
However, I keep meticulous records of when I get gas, and according to my numbers I had at least 5 gallons left in the tank. Sure enough, the tech topped the tank up, which only took 4 gallons, so clearly my tank was not empty when this happened.

My wife started up my 2005 GX470 this morning to go to work and drove maybe a half mile before she noticed a problem. So she turned around and drove it back home in limp mode. She put it in park and got out.
Most of the Warning Lights are on ( VSC OFF, VSC TRAC, Anti Skid, Check Engine etc). I tried moving the shift lever but there was some resistance and some grinding noises. And it now seems to be stuck in neutral.
How to diagnose this myself? We only drive this vehicle in the winter, and it was fine the last time we used it.

We are having an intermittent issue with car starting up and immediately throwing a CEL, red triangle and going into limp mode. Shutting off the car and restarting it sometimes resolves the issue. I'd love to be able to pull the logs from the car to see what is causing this issue.

So this morning I was driving to work - normal driving no hard accelerations. As I stopped at a trafic light the car felt going into a limp mode? - engine started to misfire - no smoke from exhaust - but felt is was going to stall. Also the idle started fluctuate from low 600 to high 1100. At low RPMs the engine felt stalling but when I drove around 3000 RPM in 4, 5th gear felt fine.
I was able to plug in the APR dongle and got 7 fault codes: 1)DTC Not Found, 2) Idle Air Control System RPM HIgher than Expected; 3) Random/Multiple Cylinder Misfire Detected and 4,5,6 and 7) Cylinder 1,3,4,2 Misfire Detected.
I am APR 1+ with VWR CAI, 20K on 93 oct.
Coil? Injector? Manifold? HPFP?

I have a 2007 Prius and it will be my first car once I get my license. It has a bad traction control computer and is stuck in limp mode. I have a neighbor who has worked on these and will show me how to replace it. Right now I have two questions. I keep coming up with how to disable it not the actual part.

My wife and I are driving our 2005 Prius with 130k miles and have experienced some weirdness with the car while driving. We've got the master warning light (red triangle w/ !), and another yellow (!) warning light, plus the center display shows a red car with an !. I've gathered that it means something possibly with the brake controller, so when I parked I put the e-brake on.
The car was driving fine with these lights on (we were in the middle of Canadian highways and couldn't stop anywhere) except that cruise control would not work.
Eventually, it actually went into limp mode, where we would floor the pedal and the car would barely accelerate. Pulled over, turned it off for a few minutes, then back on and it drove fine, warning lights still on.
I just replaced the driver's front wheel hub, and I can hear the passenger front going bad, so I'm suspicious that this may be related. Just replaced the 12v within the last few months with an Optima.

I have been battling a big boost upon acceleration at stoplights for approximately 6 months. Now twice I have gone into limp mode and the tech reads: PO700 (Transmission) and PO731 (Gear 1). I just turned over 190,000 miles but only purchased it a year ago. What is the problem(s)?

I have a 2005 2.7L Santa Fe that was shifting poorly and getting stuck in limp mode intermittently. I read up on it and found that it was probably an issue with the input/output speed sensors. The codes confirmed my suspicions and I replaced both the input and output sensors. The codes cleared and the tranny shifted like a dream. Unfortunately after 2 days and 100+ miles the car suddenly started down shifting randomly on my way home from work. The CEL came back on and the car went into limp mode. Could the sensor have gone bad again? Or could it be the wiring harness that plugs into one of the sensors? I don't understand why the car would be fine for a few days and then all of a sudden be acting the same way.

Nissan XTerra 2005 transmission RE5R05A. Trouble code is p1757 When I go from park to drive it goes out of gear and puts my car in limp mode. I took it to the dealer and they told me that I have to replace a transmission another place told that it could be brake solenoid or oil filter. In third place they told me it could be the TCM problems.

Happened once or twice where I tried to back up a hill and the car went into limp mode. Neither the dealer nor my mechanic could replicate it.

Took my 2005 Prius for an oil change. Dealer called and recommended fuel injection service because of carbon buildup and mileage (50,000). On my way home on a mild day with heat and AC off it didn't shut off at stop lights all the way home. Battery was charged. Never had this happen before and it's demoralizing because I really love my car!

Got a 2006 GX throwing a P2445 code and car goes into limp mode. Is this the Air Injection Pump? Where it's located?

Wife come home the other day after leaving for work with the truck no going past 20KM to 30KM.. After some investigating it seems to be in Limp - In Mode. There was a Check-Engine light & after further investigation found a Vac hose with a leak, repaired this & test drove. Same issue.... then there was a loud hissing sound from the engine area so I investigate & now found the EGR sensor (DPEF pressure sensor ) had blow a hose & fried the sensor.
New sensor was replace along with 2-hoses cleared the engine light but the truck still will not go more then 20KM or 30KM max.. I checked the EGR valve with vac pump & engine stalls or so the valve is good. I have left the neg cable off the batt to try & clear the Limp-In mode without success. Looking for a way to clear the limp-in mode or do I need to clear it with a scan tool?

Maintenance Mode is useful for running the engine continuously without it shutting off, such as when you do a coolant drain and fill and want to purge air out of the cooling system. This thread was created to clarify the procedure for engaging Maintenance Mode on the G3 Prius after attempting to do it according to the Prius service manual and finding that the manual does not clearly describe or include all the required steps.
Perform the follows steps in less than 60 seconds to engage Maintenance Mode for the G3 Prius.
Begin with the car and all accessories turned off.
Set the parking brake.
With the car in Park, and your foot off the brake pedal, turn the Power Switch "On" by pressing it twice.
With the car in Park, and your foot off the brake pedal, fully depress the accelerator twice.
Step on the brake pedal and use the shift lever to shift from Park to Neutral.
With the car in Neutral, and your foot off the brake pedal, fully depress the accelerator twice.
Step on the brake pedal and press the Park switch/button to shift from Neutral to Park.
With the car in Park, and your foot off the brake pedal, fully depress the accelerator twice.
Check that "Maintenance Mode" is displayed in the multi-information display.
Step on the brake pedal and then press the Power Switch to start the engine.
Important: DO NOT drive the car in maintenance mode to avoid damage to the transaxle.

My 2011 Prius does not have an MFD since mine is the standard model. I tried to find a way to monitor the 12V battery by searching the forum but could not find a way to enter maintenance mode without the MFD. How to put my Prius on maintenance mode?

I am one of the few that has ADC on my 2004 V10.
Occasionally, 3 times now. I press the ON button and the cruise control does not initialize properly. After a while it will say "Temporarily unavailable" . The problem is that then there is no power any more.
I stop on the hard shoulder of the motorway, engine off, engine on and all is reset, ADC works ok and full power is restored.

I was once the proud owner of a 2006 Prius with 106,716 miles on it. Never missed a regularly scheduled service. Now, I am no longer proud, but just another owner of a Prius with a failed transaxle.
Last week, I parked my car on my way to work and, while the car was idling in park, the Triangle of Death (red with exlamation mark within) came up on the dashboard. The car went into limp mode -- it was unable to shift into drive or reverse -- so I had it towed to Darcars in Silver Spring, MD. They thought the original 12v battery was dead, so they replaced it.
P0AA6 -- 526 and 613 codes 600 miles after Transaxle Fluid Replacement...

I was driving home. Problems started after pulling away from a 4-way stop. Truck started lunging almost like I was running out of fuel. Then I got a "Transmission Malfunction" in the in dash display. Followed by limp mode. I checked the Faults when I got home. I have the following:
P0720 - Powertrain - Output speed sensor Circuit
P2106 - Powertrain - Throttle Actuator Control System - Forced Limited Power (From what I understand this is associated with limp mode. Not a root of the problem)
P0713 - Powertrain - Transmission Fluid Temp Sensor Circuit High Input
P0722 - Powertrain - Output Speed Sensor Circuit No Signal
The vehicle has around 192,000 mi. Replaced cam phasers in upper engine roughly 1000 miles ago and replaced all the bearings in the rear differential roughly 100 mi ago. I haven't messed with anything on the transmission. Checked fluid level and color of transmission fluid.
