I'm a bit high and feel like I'm on a roll. Start spraying until you use up the can. Relative Throttle Position - 0. This all happened this time last week so … Read more » Hi, The supercharger is designed to pump more air into the engine than it would normally use. The Audi A3's engine should perform as well as it did when it. I am having an rpm oscillation at very light throttle and all of my tests so far seem to be pointing to the throttle body. Use a to measure live data at the sensor connector.
There is a snow screen inside the intake before the throttle body that can get clogged up pretty good. Time Since Engine Start - 1212 Sec. There are a couple of computer sensors there that should be checked- the Throttle Position Sensor has a lot to do with smooth acceleration and steady off-idle like high speed driving. Low battery voltage will skew your live test data and make a correct diagnosis nearly impossible. Boost Pressure System Monitor - Not Supported. So m y Son reports today that while stopped at a stop light.
O2 Sensor Monitor - Complete. If I don't take it out, I won't have to recalibrate it, right? Battery voltage is used to maintain a high temperature across the element. Failure to disconnect control modules could result in module damage when using the on the resistance setting. Could it be the case that the slight hesitancy might be to do with the pedal position during acceleration, and nothing at all to do with revs?? Should I definitely take out the throttle body or is there any way to possibly clean it without taking it out. Heated Catalyst Monitor - Not Supported. Step 2 — Disconnect the air intake hose The intake is connected via hose clamps. This is what you need to address.
Control Module Voltage - 14. This excess air creates a boost pressure in the intake manifold. Remove these bolts, and the throttle body will come right off. It no longer is accurately tracking how hard the fuel pedal is being pushed. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Commanded Equivalence Ratio - 0.
Even a good cleaning is going to cost a good deal in labor, so save your hard earned cash and get this job done in your own garage. Use the scanner to retrieve and record all trouble codes. When boost is not desired, such as during idle and light throttle cruising, the excess air is routed through a bypass passage between the intake manifold and super charger inlet. The symptoms which could accompany this code include a reduction in fuel efficiency, decreased engine performance, and significant hesitation upon acceleration. Use a good throttle body spray cleaner and don't be shy with it. Sprayed the 4 plugs and sockets with electrical cleaner but they all seemed mint anyway. This action is controlled by a bypass valve which is connected to a vacuum source.
By - April 25, 2016 This article applies to the Audi A6 C6 2004-2010. Look for leaks manifold in the intake and clean the carburetor using the carburetor cleaner. Audi Q3 P0121 Diagnosis A good mechanic will utilize a scanner to diagnose when the codes were set and reset them. Do not ever try to manually open the butterfly valve in an electronic throttle body with your hand or any other tool. Taking this into consideration, it is always important to fully test every aspect of a circuit to diagnose an electrical problem correctly. Fuel Level Input - 93.
What are the causes of the P2138 code? The butterfly valve needs to be cleaned from the front and inside behind it as well. Same here, as i said above and murran confirmed, i would check the wiring first and only move to the pedal in the last instance.

How to Fix This simple diagnosis above could easily reveal the source of the problem of the error code P0068. This alignment experimentation will have to wait until later and it is there that I hope my photos will help to clarify much of what I think I have learned from this project.
Here are some pics for the throttle body steps. Put it all back togetether just as it started raining. Obtain sensor and circuit resistance data from the service manual. What are the symptoms of code P0068? It is connected via impossible Audi clips so I replaced it with the metal band with tightening screw from Autozone for the next time. I would warn you from doing it after beers though. Commanded Evaporative Purge - 62. This, however, is a generic term for error code, which means it applies to all makes and models of vehicles since 1996 to present.

However, as said earlier, qualified mechanics may need to conduct specific diagnostic steps, depending on the make and model of the vehicle. This article applies to the Audi A6 C6 2005-2011. Begin every diagnosis with a visual inspection of the related components, connectors, and circuitry. This can severely damage the electronic throttle body motor and possibly prevent the vehicle from being operational. I measured the airflow before and after the screen was cleaned. You now have access to the throttle body and can remove it.
