How to Test an ABS Speed Sensor

1. Elevate the rear of the vehicle in a secure position with a car jack, and place it on jack stands. Place wheel blocks around the front tires. Remove the rear tires to test the ABS speed sensors.
2. Locate where the engines electrical wiring harness meets the sensors electrical wiring harness. This is generally in proximity and secured around the strut housing in the wheel well in the front and the shocks in the rear.
3. Remove the sensor from its position using a quarter-inch ratchet with an 8- to 10-mm socket, which is generally located by the heat shield on the caliper.
4. Examine the end of the sensor. If it looks like a big fur ball at the end, then too much contamination is disrupting the sensor.
5. Spray the sensor with brake cleaner and wipe with the rag to remove contamination. Contamination on the sensor can send erroneous signals to the computer.
6. Disconnect the engine harness from the sensor harness. Set the voltage meter to Ohms, and connect the positive and negative terminals of the voltage meter to the input and output on the sensor. If the voltage meter registers as infinity, then the sensor has failed and needs to be replaced.
7. Switch the meter back to Volts, if you do not see an infinity in the ohms setting. If the voltage meter reads above 5 volts, it is starting to fail and can cause intermittent problems. If the voltage meter reads below 5 volts, check the knock sensor for corrosion and check the electrical connections leading to the knock sensor.

EVO among first to finally test Aston Martin One 77

EVO among first to finally test Aston Martin One-77 Coming in at a cool $1.87 million, were happy to hear that the car drives as well as it looks. The video does a great job of providing plenty of in-depth information on the car as well as some killer driving shots that really let us hear the cars exhaust note. Considering that we usually only see this car gleaming under the lights of an auto show, the best part of the video might, in fact, be the closing shots showing the sea foam green, super exotic covered in road grime.

With only 77 (or maybe 76) examples of the Aston Martin One-77 on the earth, the only thing rarer than the car itself are reviews or test drives of it. Evo Magazine, however, recently had the opportunity to slide behind the wheel of the limited-production Aston Martin supercar. In what it claims to be a world-exclusive, Evo not only got to drive the One-77, but it did so along some incredible roads in North Wales.

How to Test an Audi Cruise

1. Locate the cruise control bar, usually located to the left of the drivers wheel. Along the edge of the bar will be the word Set, and you will see buttons for controlling the Speed.
2. Drive the car to your desired speed, and then pull the bar towards you until it is in the On position.
3. Click the bar up or down to increase or decrease the set speed.
4. Click the Distance forward or backward to adjust the amount of distance you want the car to keep from the nearest car in front of you. Note that this feature is only available for models using the adaptive cruise control system. You will see two cars on your driver control panel showing you how the distance is set.
5. Release the brake and clutch pedals, as pressing them will disengage the cruise control system. If the cruise control didnt work at first because you had your foot on one of these pedals, pull the bar towards you. This is the Resume setting, and it will re-engage the cruise control. Your car should then keep the set speed.
