SOURCE: Zero throttle response and sluggish accelertation

Wow, great description...I suspect the catalyst is bad...(in the exhaust) but try this cheap fix.
go to Advance Auto Parts and buy a can of "SeaFoam" ($8) and following the directions add to fuel and drive for at least 100 miles...see if that helps...if not, have a mechanic look at the catalytic convertor/exhaust
Good Luck

SOURCE: 96 camery sometimes stalls when come to stop or sitting idling. new plugs,rotor,cap, wiresair filter, o ring on distributor cause oil getting in, throttle body gasket,cleaned throttle body, did unplug

Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Throttle Actuator Control - drive by wire


1.5) TAC - Throttle Actuator Control
What is it? Some vehicles have indirect throttle control "drive by wire". Instead of the accelerator pedal position being conveyed directly to the throttle plate by cable linkage, it is detected by an electrical sensor and this is fed to the ECU. The ECU in turn sets the position of the throttle plate appropriate to the sensed position using an electric motor. The throttle plate position is, in turn, checked by the throttle position sensor and this signal is sent to the ECU to confirm that the requested throttle plate setting and its recorded position are in agreement.

Where is it located? The first part of the TAC is located on the inner wing/fender and consists of rotary device to which the accelerator cable is attached; the degree of rotation (pedal depression) is detected electrically and this is signalled to the ECU. The second part of the TAC is located on the throttle body and acts on the throttle plate shaft.

Symptoms of a faulty TAC
Associated OBD2 error codes DTCs: P0120, P0124, P1516; P2102, P2103;P2111 - P2118

  • Sudden power loss/limp home: If the ECU detects any fault with the throttle actuator control directly or with the position feedback via the TPS it engages an immediate engine shut-down to either idle speed or limp-home speed.

How to fix? The TAC is part of complex systemand the failure of the TPS has to be eliminated first as a possible source of error. A simple electrical connection failure can also give rise to the shutdown so all associated connections should be checked to ensure that they are clean and bright to allow electrical continuity.

2005 ford five hundred replaced battery went into engine failsafe mode n will only idle no throttle response I replaced throttle body assembly just sits and idles


try using the scan tool to reset the ECM program
code p 2104 refers to throttle actuator control(TAC) system---forced idle mode ===causes ---wiring--TAC motor ---APP ensor--ECM
code p 2112 refers to throttle control actuatorTAC system---actuator stuck closed ===causes ---throttle body, throttle valve tight/ sticking
or TAC system--circuit malfunction===causes wiring short to positive ---short to ground ---throttle position sensor--- ECM

PROBLEM: LACKING POWER, AND EXPERIENCING SLUGGISH ACCELERATION


Guessing here, might help to know the make/model/year/engine.
Sounds like you're running in "limp mode" because one of your sensors is either bad or simply not hooked up. Perhaps TPS (throttle position sensor) or MAF (Mass AirFlow)

Where is the throttle body located?


old post , and great question

the TB is a thing that contains the AIR throttle, the body holds

that TV throttle valve (or some call it a TP throttle plate)

this car has 6 engines, and varies by country. what country>?

what engine? (USA cars have a hood EPA tag, it states the engine)



sure cleaning it can help and for sure with throttle by wire.

the body gets full of EGR/PCV crap. (called GUNK) and if not

removed on high mileage cars, it jams the silly throttle by wire

motor. (and related\'s)

why not scan the PCM and SEE ALL DTC errors.

that be first. !!!



loose power has many causes, up to 50.

why not scan it first, (the CEL lamp to me is useless , unless stuck on)

scan it first.

this engine has many limphome modes (suzuki failsafe)

and will run slow. in limp mode.

scan it.

the TBW , throttle by wire has it\'s own limp mode.

the transmission too, and others.



The TBW has up to 4 TPS sensors. 2 on the foot and 2 in the TB

if ANY of the 4 , do not AGREE, you go to LIMP HOME MODE>

or end up like a Toyota and huge class action lawsuits.



loss of power, not transmission caused, (slips or skips gears)

is engine power loss.

cause by (top ones of 50)

1: never getting a tuneup. and for sure the 60k mile.

2: misfire, caused by 3 major things. ask.

3: flooding.

4: bad spark see #1

5: clogged air filters see #1

6: clogged fuel filter.

7: weak fuel pump.

8: and the big one is loss o f engine compression for huge list of causes.

9: not scanning the PCM and believing what it told you. !!!

Hi my Saab 2001 93 2.0 turbo convertible has lost power get into limp home mode I reset it every few weeks codes come up p1105 p1260 p1251 p 1264 what do u think is wrong ?


code p1105 refers to manifold absolute pressure(MAP) sensor, TC system-leak detected. causes ---intake leak, ---hoses There are to references to p1105 The second response is still map sensor but the causes are---TC system--mechanical fault--air leak between throttle body-TC,map sensor---TC system--exhaust blockage
code p1260 refers to throttle return spring--weak spring force. causes ---mechanical fault,--,throttle control unit
code p1264 refers to throttle valve opening-accelerator released causes ---throttle control unit---mechanical fault
