IS F (2008-2014) :: Car Went Into Limp Mode When Restarted
Jan 6, 2016
I have a 2008 ISF with a k&n intake and QTP exhaust cutouts. About a month ago my car died on me and when I restarted it, the car went into limp mode. The "check vsc" light is on along with the traction light and CEL. I took it to my mechanic and he said I needed to replace the MAF sensor and I did. 100 miles later the car went into limp mode again. So I took it to a mechanic that knows Lexus vehicles very well apparently, and he diagnosed it to be my intake. So he replaced it with the stock intake. Now I've driven another 100 miles and the problem has come back again. The car is throwing all kinds of codes when I connect the obd2 scanner to it.
It is throwing p0031, p0037, p0051, p0057, p0102, p1360, p1361, and a whole bunch more.

As I pulled into a parking lot last night, my "check VSC" warning message came on. Simultaneously, the Parking Brake light, ABS light, Traction Control, and VSC lights came on. The car did not go into limp mode though, and the car seems to operate as normal (even when going WOT).

Was on the highway cruising along and punched it to pass a slower vehicle. As I've done many times before without issue. Got a flashing CEL and it went into what I assume is a type of limp mode. I reduced the throttle input to the point the CEL cleared and full power returned. I did not have to stop the truck and key-off etc. I also made no further attempts to see if it would do it again. What causes that? Kind of annoying to pull out to pass and you hit limp mode.

Truck: 2009 F-150 Lariat SCrew 5.4 4x4 with 6.5" bed
For the last few years, I've had this intermittent problem where the service engine light (wrench icon) will pop on and the truck will go into limp home mode. While it's in this mode, all of the indicators on the dash freak out. Low fuel warning will come on, temperature warning, low battery voltage, etc. Turning the truck off and back on (sometimes a couple times) is enough to get it back to normal, albeit with a check engine light that needs to be cleared. It's happened infrequent enough that I've just been dealing with it. I got the codes a couple years back, but there wasn't much information available on what the potential causes might be. The Checker Auto parts database suggested one might be related to a wheel speed sensor.
Well, this afternoon it happened again, and I was near an O'Reilly, so I took it in to pull the codes. There were 9 total in the system; 5 of which were unique:
B0025
B00D5
U0073
U0100
U0253
They didn't have any information on what was causing them. What could be causing this. I'm getting sick of having to clear the check engine light and worry about the truck falling into limp home mode when I'm at intersections.

2008 sonata 3.3, no reverse however the dash indicates it's in reverse. Code P0733. I understand how an unrelated problem can cause another and wonder if I can eliminated possible problems. Car is in limp mode and stays in second or third gear.
I am about to disconnect, clean and wiggle the connectors for the transmission inner and outer sensors and then find out if I can test the sensors. That is, after I find them.
I'm also on the hunt for anything the TPS sensor might have to do with it. Battery disconnect does not work, even after hours. Is there any way something unrelated like the brake light switch or the inhibitor switch (whatever that is), might be the cause? Valve body?

I'm a little bit stuck here. This happened last night, and the dealer is closed today. I have a 2008 Santa Fe SE. It stalled last night, and when I turned it back on, I got a check engine light, the ESC light, and the AWD transmission light blinking. When I go to accelerate, it will not go passed 2000 RPM, and it is driving very sluggish. Its not knocking, or making any other kind of sounds. The air conditioning does not work, but the fan blows uncooled air. It accelerates extremely slowly, even with the petal mashed.
I plan on taking it in tomorrow, but I'd like to know if there is some way to reset the computer. I tried disconnecting the battery for about 30 minutes, but it didn't work.

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.

I just got an Egde Evo which I installed and everything looked great. After a few runs, I noticed the ABS light coming on an soon after that my transmission goes to limp mode (the wrench lights up).
I receive the DTC error: P2106 on the Edge Evo.
I have gone back to Factory default, but it keeps coming back, ie. the ABS light lights up and the Trans goes to Forced Limited Power (according to the Evo).

Replaced HPFP 38,000 miles ago. Truck began going in limp mode without engine light, wrench came on in dash, gave codes for brake switch, anti-theft, some other weird codes. Had those codes cleared, ran for while then water separator came on, drained the water out, came back on. Read some forums, so I removed and cleaned the housing, cleaned off the sensor. Had code cleared and ran good for about a week. Then guess what engine light comes on, limp mode.
Went to Auto Zone, pulled code P0088. This truck runs awesome until limp mode. No other problems. I take it to the ford dealer, scanner pulled P0088 and the water separator code again. I have read alot of remarks about this P0088 code. Can there be another cause for pulling this code, only 38,000 miles later. I had them do the TSB 12-07-07 but I have also read it can only be done if the P0088 is the only code. I just really feel there is an underlying issue with these 6.4's.

So i noticed, when in auto mode, whether sport mode is on or off, it does the same thing. If i floor it from a stand still, the transmission takes noticeably longer to go from 1st into 2nd then from 2nd to 3rd, 3rd to 4th, etc. 1st to 2nd takes like a good second, kinda like this:
1st VROOOOM.....................2nd VROOOM..3rd VROOOM..4th.....etc..
If I drive it in manual mode, then it shifts just as fast. So this only happens in auto.

I have a 2008 F350 with a 6.4 Powerstroke diesel engine that just experienced total engine failure. It has around 65K miles.
There is a heavy burn star pattern on all 8 pistons, a few pistons are cracked, a few cylinder walls are scored, glow plugs are melted, both heads are cracked with multiple stress fractures in each head.
About 1 month previously, the transmission would not work in tow mode and caused the engine to go into limp home mode. The dealership just replaced the entire tranny as a warranty item. About 1 week before the engine failure, I put in a 5.25 oz bottle of Lucas injector cleaner with a full tank of gas.
The Ford dealership is saying that the star pattern on all 8 pistons is due to high pressure fuel overspray and is evidence that I had a tuner on this engine and that the warranty is invalid. I did not have a tuner. What might have caused this engine failure?
Also, they only ripped down the top half of the motor, not the bottom half. I heard this might have been caused by a cracked crank shaft, but Ford refuses to investigate this possibility.

I've owned my 2011 IS-F for a couple of month now. I know the Sport Mode give the car crisper throttle response and it shifts quicker. Does the Sport Mode do anything else?

I have a 2006 Charger R/T. My car used to not start (even thought the battery, starter, and alternator was good). I had it fixed, and the problem seemed to be electrical. However after that, it would always start, but would go into "limp mode". I let it sit for two days, and the limp mode disappeared. However, it will only start on occasion. It won't start after about 30 mins after use. It won't start for a few hours. All electrics work fine, it just won't even attempt to crank. Try to start it later, it will work fine. Even though the check engine light was NOT on, I was able to pull three codes out of it: U0100, U0103, P0700. I did have to replace the notorious "pink thingy", but everything (should be) connected fine.

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.

So I was driving kinda hard yesterday on the highway, and it was about 80 degrees outside. At some point in the drive, I got no boost from the turbo at all (my gauge also was showing no boost). I pulled over, stopped the car, and restarted it, and the car was back to normal. Is this something I should be worried about? I am running 93 program APR Stage 1+ with VWR intake and HPFP.

My 2007 Santa Fe was acting up at one time, then stopped doing it, and recently started again. My wife is the primary driver so I'm not always in the vehicle when it happens. When the vehicle is started cold, it will run a short distance then the MIL comes on and it goes to a 5 mph limp mode. After pulling over and shutting the vehicle completely down for a couple of minutes, it will run normally with the MIL still on. However, by the time I get back home to pull the codes, the MIL goes off. I don't remember the exact codes, but when it acted up last time I believe the codes had something to do with the TPS, Pedal Pos Sensor, and one other I can't remember.

I have been having a problem where the Santa Fe will drive great for a week, sometimes only a day and the engine light will come on and the car will go into limp mode. It will drop you from 65MPH to 10 MPH, if you put it in park the RPM's will race and stomping on the pedal will not affect the RPM's. After you turn it off for a couple of minutes it will drive ok again. I have replaced the Throttle Position Sensor and the Accelerator Pedal Sensor, cleaned all connections and checked wires in them. I have also cleaned the Throttle Body. The Dealer wants to replace the Throttle Body.
Had Engine Codes:
P0123 - Throttle Position Sensor 1 Signal Circuit High Imput
P1110 - Throttle Actuator Control System Malfuntion
P0222 - Throttle Position Sensor 2 Signal Circuit Low Imput
P1175 - Electric Throttle Valve Control System (ETS) Valve #
P1196 - Throttle Actuator Control System Limp Home-Stuck

So on cold mornings my r has been kicking on the epc light and gone to limp mode. The only codes are for the coolant temp sensor and an intermittent accelerator position sensor. Would the temp sensor really cause this? After awhile I can start it up and it runs fine.

My 2010 Malibu has been throwing a code 0f 2135 also goes into limp mode. Code comes up as throttle pos sen. So looking I can see it is all built in one with the throttle body. Can it be changed with out any special tools?
