Check the battery and the Alternator. Sometimes with these Saabs, when the alternator or the battery start to go bad, you will have many different symptoms all to do with just one issue. You can remove the battery and the alternator, take it to a parts store and they do free testing on those and they can tell you if either is bad or not. The Alternator needs to be out of the vehicle to be tested.

1996 Dodge stratus es automatic wont shift outta low gear .is this a sensor issue?


probably not if it is limp mode
the ECM puts the car in limp mode to prevent serious problems in the engine or transmission
could be no coolant, sump oil , transmission oil etc
run the fault codes and find the reason for the mode

1993 Isuzu NPR when taking off transmission shifts good but after bout 1/4 mile downshifts out of overdrive and will not shift into of again until it sits and cools for a little while


Many of todays cars have a mode called Limp Mode. The Motor and Computer talk to each other and if faults are found? The Limp Mode (( Short for Limp on home mode )) will be set in the Computer. Go to your local Auto Zone and ask them to Scan the OBD 2 fault codes with their reader. Or pay the dealer. It may be something really simple. My Check Engine light was on the other day because the Gas Cap was loose. This Scanner told us the problem and we tightened the Gas Cap. After 3 times driving the car with it tight .... The Check Engine light went off.

Oil light is on and engine in limp mode


check the oil level in the sump, coolant level, coolant temperature (overheating), transmission oil level if auto. The limp mode is energised by any number of sensors that register a fault that is detrimental to the engine/ gear box. Run the fault codes and repair any faulty units . Reset the CPU with a scanner .

Why does my vauxhall signum 2.2 diesel keep going into limp home mode


It might be faster if the car was brought to a shop for diagnostics. The ECU has detected a fluid issue and the engine is protecting itself. Check the oil level and transmission fluid. Also check your records and see if the vehicle needs an oil change, transmission service, or antifreeze service. It could be related to your brakes but it that was the case. You have noticed other warning lights. Please write back and let me know what you found or if you have other questions, good luck.

Car stays in 2nd gear all of the time. (Limp mode) Fix Engine light stays on, D green light blinks constantly for automatic transmission Honda Accord 2005


Ah, I see. You want to outsmart the computer? Right logic, wrong computer. I think the problem is not in the transmission, but it is the engine computer that has communicated with the transmission computer and put the car in limp-in mode. The fix engine light is sent from the engine computer, and this is the main computer in the car, the main drive train computer, if you will.
The short answer is yes it will reset, by just unhooking the battery. Won't do any harm. Start it up about an hour later, and be sure and let it warm up to normal operating temperature (closed loop) before you take it out for a test drive. Otherwise you may be miles from home in 2nd gear limp-in mode again.
The real fix is to talk to your car...like communicate with the computer and get those trouble codes read...talk to it nice, not the abrupt tone of the glaring idiot light, and maybe it will respond in a kinder, gentler easy to fix diagnostic code!!!!
Good luck.

2002 Impala: transmission limp mode...


Most transmissions have a limp mode, or limp-home mode.
If the driveline computer thinks there is something wrong, it can lock the transmission into one gear, such as 2nd gear. Usually reverse will also be available. The Impala automatic has 4 speeds. 2nd speed or gear will get you home, but the engine rpms can get a little high. I wouldn't get on the expressway will in limp mode.
Before taking to the shop, you might want to try and reset limp mode by turning the car off for a couple minutes, or you may have to disconnect and reconnect the battery.

Trans stays in limp mode, speed sensor has been changed,speedometer does not work, if speedometer head was bad or unhooked,would that cause mw problem? It is a 1995 chrysler cirrus


Hi,
Your engine management and maybe even your transmission is controlled by the ECU. As such, many ECU units are fitted with a 'limp home mode'. When it detects that something semi-serious is wrong, it enters the limp mode, which means that the engine won't rev beyond a pre-programmed speed, you can't accelerate very fast, or you may indeed be speed-restricted to 40 mph or similar. The transmission may even stay in one or two gears. The alternative would be to either let you drive at regular speeds, with the danger of letting you trash your car or stopping you from going anywhere .
You should have a Check Engine light. Go to a major chain auto parts store and they should read the ‘code’ for free, then go to rdtiburon.com and ask what the code actually indicating or is really bad to your car. They will advise you what you ought to do.
Because you replaced the speed sensor and are still experiencing the problem, we suspect that you have a faulty speedometer cluster.
Please check this link and go through the article to have an indepth knowledge to your problem....

96 Yukon Transmission


Check the transmission fluid level and condition of the fluid. It should be bright red like Strawberry colour. If it's dark like burgundy, then the fluid is burnt and the transmission needs to be serviced. Fluid and filter changed.
Have the Truck's computer scanned for any DTC codes. Most parts store like Auto Zone or Parts Source will scan for free. If there is a engine management Issues, it may be running your Yukon on a limp mode.
Limp mode will not let the transmission shift past 3rd gear and the OD does not engage, i had a cracked ignition cap and the computer put me on a limp mode once. 
Good luck and hope this helps. Keep me posted to please.

Can a toxic fume filter send a megane 2 into limp mode


Not directly, but the engine ECM and Transmission TCM are connected, so if the engine is running badly, this will effect on the transmission, and may confuse the TCM and make it go into limp mode.
Hope this helps
