Limp mode problems

Izusu rodeo sport 2003 V6. We have changed the air mass sensor. The throttle sensor and the throttle body sensor. It ran great for 10 days then went into limp mode again on a long drive on a hot day. The throttle body sensor solved 90 % but not completely. It has 200 K on it and has been great until 200 k then started going into limp mode. Any suggestions ? Apparently a common problem with this vehicle. Phil

SOURCE: 01 Isuzu Rodeo LS loses acceleration after running for a while

This is a complex problem.

Do you have any repair record of the Rodeo LS?

When is the last

ignition module change?

fuel pump change?

fuel filter change?

DO YOU TOP OFF during gas refuel?

Are you able to get the OBD-II codes off the ECU?


I will check fuel rail pressure first to rule out the fuel pump

add Chervon fuel injector clear and fill gas to above 1/2 tank

locate the ignition module and apply GOOD amount of white lithium grease to help it from over heat.

When the truck stall again check the temperature of gauage......Engine should be below 195F

Let the module cool and see does it ran well again.

Good luck

Where is the mass flow air sensor located at for my 2004 Isuzu rodeo

no engine stated,
my guess v6, as ONLY the V6 had one,
and not all V6 have it.
so, NO V6 size stated or the
8th digit of your VIN code stated, (engine code)
so no answers possible.
there are at least 4 V6 engines generations used.
the last engine is the most comlexe with VVT (3.5L)
it has MAF, and is between the TB and the air cleaner.
on all cars with a MAF, some are in the TB.
facts all
post a vin
i post photos,
sorry not posting them all on both engines 2004

TB = Throttle body, that magic place that sucks huge air.

2014 jeep compass codes po171 and po2173read I changed Oxygen sensor but limp in mode I then changed throtle pedle but limp mode returned how can i fix this ?

code p 0171 refers to system too lean bank 1== causes --intake /exhaust leak---AIR system---MAF/VAF sensor ---fuel pressure/pump--- injectors--- Heated oxygen sensor
by changing the O sensor (oxygen sensor ) you changed the wrong one and so there would be no change to the read out there
code p 2173 refers to throttle actuator control (TAC) system -high air flow detected ===causes --intake system---throttle body
fix the causes and you stand a chance of fixing the problem

2003 Montero Sport 3.0L, 135K miles. Cold start, idle ok. Once warm, low idle and sounds like it has a miss.

Your going to need a wiring diagram. You have a MAF,MAP, IAT and EGR sensor problem. My guess would be a signal wire or ground is bad. These four sensors are right at the throttle body. The mass air flow sensor and the manifold absolute pressure sensor are one in the same. The intake air sensor is next to it. All are located in the air induction plenum. Between the throttle body and the air filter. The Engine gas recirculation valve/sensor is right behind the throttle body. So check the harness from the air filter/ MAF to the engine harness plug. Look for conduit that is rotted away and/or melted.

What is wrong if wrench is showing

I would imagine the car is not running properly right now but when the wrench light comes on it is in "limp mode" you should find someone who can hook up a scan tool to see what the problem is. Some of the easy things to check that can cause it isa loose gas cap, poorly seated air filter, if your comfortable doing it you can clean you throttle body or mass air flow sensor as well.

My 2006 KIA Sorento won't idle and is pecking!! I just had 3 ignition coils put in and new spark plugs because of the same problem!! It ran great for a week, then the engine died at a red light!! When I...

SOUNDS LIKE the throttle position sensor (tps) (will cause surging), or mass air sensor (mas) if equipped (or your equivalent) Unplugging the mass air sensor will cause the computer to switch to limp home mode, which will clean up the idle till you replace the sensor, ( usually located on the air intake tube or at the air cleaner) These are sometimes on the ame circuit as the crank sensor (picked up on the scanner), but the coils and crank are totally the wrong direction.

I own a 2003 Nissan Altima SE 3.5L. Recently, my car sounds like it is stuck in 2nd gear. The RPM's do not run high but the car sounds like it is racing in second gear. This is an automatic. Help?!

If your service engine soon light is on, go to autozone and have the code pulled up. Sounds like you are in limp mode (safe mode). I suspect it is your mass airflow sensor. Its easy to replace but expensive. I recommend getting one from a junk yard and installing it yourself. if you dont have any mechanical experience dont worry. As soon as you see one it will be obvious you dont need experience. It is in the middle of the big tube that connects your air filter to the throttle body. All you need is a screw driver and disconnect one electrical connector. Again, not worth buying new...they cost over $350 new but only $60 at junk yard.

If you want a quicker way to check, dissconnect the big tube from the intake manifold, in essance letting air run directly to the throttle body without going thru the air filter or mass airflow sensor. If the car runs fine with it dissconnected, its the mass airflow sensor. Buy some mass airflow sensor cleaner at an auto store (its specifically made and named mass airflow sensor cleaner). Try to clean it first...Dont touch anything inside with your finger tho.

Sorry if Im sounding like a school teacher but Im not sure of your mechanical knowledge or ability.

If not none of this works , you will have to pull up the code.

Car bucks and stalls unless mass airflow sensor is disconnected. Changed airflow sensor and temperature sensor. Also changed air filter. Engine light remains on.

Clear and recheck your codes. You may have another problem that taking off the MAS is masking. Throttle position sensor being stuck is a common issue as well.

With the MAS off the car goes into "limp home mode" and everything gets set to base settings with no active input from sensors.
Also check your fuel pressure on the fuel rail.

Good luck and be careful.

Check engine light come on and the idle is real low

unsure which engine model you have. is a real common problem here with gdi v6 models,cleaning air mass meter(usually in ducted pipe connected to air filter) and throttle body with bottle brush and good carbon removing solvents restores the idle speed and ecl should go out. engine may be covered by plastic cover,this removes easily 4-6 bolts and allows access to throttle body failing that low idle could be limp triggers when either a major sensor faults or more that 3-4.the ecu will need to be checked for fault codes and then a plan of repair will be more effective
