Polo Sensor Light Adjustment
If the crankshaft position sensor has failed completely, then the computer won’t send any fuel to the injectors. Consequently, Leaving you unable to start the car. Check Engine Light Check Engine Light A Crankshaft Position Sensor Failure may cause the check engine light on your dashboard to come on. Volkswagen Polo Owners Manual: Rain/light sensor. Volkswagen Polo Owners Manual / Lights and vision / Windscreen wiper and washer / Rain/light sensor. The rain/light sensor will then register the reduction in sensitivity of the surface and adjust accordingly. The size of the crack could affect the way in which the sensor activates the wipers.
The throttle position sensor, TPS for short, is a sensor that is used in an internal combustion engine. These can be fuel injected engines or carbureted engines. The TPS is used to monitor the position of the throttle butterfly valve. When we accelerate, the butterfly opens a little or a lot to allow air into the intake manifold, depending on how much you are accelerating. There are a few signs that could be a signal that the throttle position sensor is failing. The first and foremost is a possibility that your check engine light could come on; this is a light on the dash that sometimes appears as a little engine or sometimes it simply says check engine.Next scenario is that the car idles rough, this is when the vehicle is in a stationary position and you get a rough feeling from the engine almost as if the vehicle wants to stall out.
Finally you may find that the vehicle hesitates on acceleration. To make a proper diagnosis we first need to get our tools in order. The main and only item in the tool list is what is called an ohm volt meter. Once you have identified the TPS sensor, turn on the ignition, do not start the car, make sure the volt meter is on twelve volts DC.
Locate the connector that goes from the ECM (engine control module) to the TPS. Once you find this disconnect it completely from the throttle position sensor.
There are three prongs; the center prong is usually the negative connector.Once this is done, take the volt meter and connect the negative side (usually the black wire) to the ground terminal on the battery. When this is done take the positive lead, (usually the red wire) and attach it to one of the other prongs. The volt meter should read five volts, if you are on the reference wire for the TPS. If it reads anything below five volts then you are on the signal wire and need to go to the other prong in the connector. If it reads nothing on the volt meter then you are on the negative connector. Once you locate the reference wire, and it reads five volts then you know that you are getting proper reference voltage to the TPS. Therefore you have just eliminated a faulty power feed to ECM.
The next step is to put connector back on the Throttle Position Sensor. Take the positive lead for the volt meter and put it to the signal wire in the back of the connector, this is known as back probing. Take the negative lead from the volt meter and put it to the center wire which is negative on the connector, take the butterfly shaft and turn it gradually and as you turn it you should get a gradual count upwards to five volts. If the volts fluctuate backwards or forwards then you know you have a faulty throttle position sensor.

Reset Your Volkswagen Service Engine LightThinking you want to reset your Volkswagen service engine light? Before we clear a service engine light it is important to know why it is on. Once we correct the problem, then we can clear the light.
Welcome to the VW Check Engine Light codes page. Below you will find the most complete list of Volkswagen trouble codes available. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? We have a large number of resources to help you repair the problem.
Here is how we suggest you proceed. Look up your code definition. This tells you where to start testing. If you are unsure of any abbreviations, check out the acronym list by clicking on the link at the left.Next, read our article, and if there is an article related to the system you are testing, such as Oxygen Sensors or EGR concerns, read these as well. They will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing.
If there is no procedure for your manufacturer specific code, then I suggest referring to a similar generic OBD II code (these are listed numerically by system type) to get a good idea of what to look for. If at this point you still need assistance use the 'Get Help' link and let us know how we can help.
We can provide information on component location, specifications, circuit color/location and more. We do ask that you please read the info available on the site first so that we can help reduce repeat questions.
So please read our and when you're ready jump in! Also, we value your feedback and like to hear stories of unusual fixes or concerns you may have run into with your Check Engine Light, so feel free to share your experiences by using the 'Contact Us' link. Let's go!We do our best to update these Volkswagen check engine light codes as frequently as possible. If you find one missing let us know and we we'll add it immediately! Please use the form on our Contact Page to get in touch with us. We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. And lets face it, if the service engine light is on then you need it now!

It's easiest to use the 'Find On This Page' feature of your browser's 'Edit' menu to find codes on this page as the list is quite long. These are listed in numerical order for easy searching.When retrieving Volkswagen check engine light codes with an OBD II scan tool, proceed as follows:1.
Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover.2. Turn the ignition on.3. Follow scan tool manufacturer's operating instructions to access the Diagnostic Trouble Codes (DTC's).Remember, these are manufacturer specific codes only.
