Question about 2004 Volkswagen Jetta

1 Answer

Is this a problem with the throttle body?

HI! Iam in need of help!! Iam having trouble with the acceleration of my car which is an 2003 Volkswagen Jetta 2.0. My car wont run as it should, i did a full tune up, and i even changed the pedal and it improved a little, but when i go uphill my car looses a lot of power, even on a straight road i dont feel it has the speed it should. I took my car to the volkswagen dealer in my country and the scanned it, they told me the throttle body was only working on a 60% and they said this might be the problem, the thing is that i do not know that if i buy this part do i also have to buy the accelerator pedal? Since i did a change and i only did it with the pedal and not the throttle body. Whenever i start my car i have to press the pedal a couple of times so that it can respond. My mechanic says that the propeller on the throttle wasnt opening as it should. Could this be the problem? If i change this do i have to buy both the pedal and the throttle body? How is this installed? Manually or with scanner? Please help! Thakn you!

The throttle housing must be adapted to the engine control module. it will take a scanner or a tool like vag-com. good luck.

1.1 mm is the standard gap for a platinum tipped plug. Plugs for this car usually come pre-set but it's always worth checking before installing. Hope this helps.

SOURCE: my epc light went on in my 2002 volkswagen jetta

Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...

You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.

My advice would be not to drive it untill it's fixed to prevent more potential damage.

SOURCE: 1999 Volkswagen Jetta will not shift good

Volkswagens are known for having trouble with their transmissions, even more so in the 1st couple generations. This problem could just be your transmission sticking when getting into another gear. I recommend not pushing the car so your running at high RPMs, slowly work your way up that hill, and even try letting off the gas it may help it shift some. If you're really concerned with it you can take it somewhere to get the transmission checked, something maybe slipping or sticking it all depends and it can be a small inexpensive fix or it could be a heck of a lot, but its all up to you.

Engine power loss message

You need to have it checked for DTC'S - diagnostic trouble codes , There is a problem with throttle actuator control (TAC) - electronic throttle control !
Throttle Actuator Control (TAC) Overview
The throttle actuator control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well.
The TAC system components include, but are not limited to the following:
The accelerator pedal position (APP) sensors

The throttle body

The powertrain control module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position (TP).

What would make my 2002 VW Passat just shut off when sitting in park?

Hi there:You will need to have diagnostic codes checked which can be done for free at parts store.

We have seen where the vehicle will run rough and have poor throttle response because the wiring right at the throttle body is bad because the wire terminals are loose right at the connector the first thing you will need to do is check the wiring and check the trouble codes stored in the engine control module to see if you have trouble body codes this needs to be the next step .

EPC stands for Electronic Power Control. This is the drive by wire throttle system used in Audi and VW gasoline models. Here is a list of some of the related components:
- Throttle Position (TP) Sensor G79
- Sender 2 for Accelerator Pedal Position G185
- Throttle Valve Control Module J338
- Angle Sensor 1 for Throttle Drive G187
- Angle Sensor 2 for Throttle Drive G188
- Brake Light Switch F
- Mass Air Flow (MAF) Sensor G70

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

No. The throttle body operates nearly the same as a carburator on an older engine. The throttle body is connected to the accelerator cable. Taking off the throttle body will not be a wise choice.

Check engine light p0411 code what must i do car drive with lack of power. I push the acceleration pedal and it takes seconds befor it accelerate, like it dont take off.

this has to do with your secondary air injection incorrect flow. start looking for a vacuum leak especially around the air duct from the mass air flow sensor to the throttle body.

Yes it does. But I would clean the throttle body first by taking off the hose that comes from the air filter to the throttle body, held on by a steel clamp. Hold open the throttle plate and spray it down with a brand name carb and choke cleaner. Keep me posted please.

XG350 2003 throttle problem

cars these day are all electronic
the exhilarate in your car is electronic the older cars used to have a cable that ran to the motor now they dont
these days the exhilarate is like a volume knob on a cd player, it tells the car to produce more power on not to.
it sends the message to the throttle body
the throttle body is in charge of mixing the air to fuel ratio more fuel more power your emmissions system is the exhaust system
all of this could be linked to the throttle body being damaged
if you want to know more just ask
hope it helps
