It is advisable to visit a local car dealership or tire shop to fix tire pressure sensors. Repairing the tire pressure sensors requires special procedures such as identifying the type of pressure sensor and rebalancing the wheels, which makes it difficult to perform at home.
Resetting a tire pressure sensor varies, depending on whether the sensor is part of a direct or indirect monitoring system. Direct monitoring systems are more commonly found in the U.S. while indirect monitoring systems are more common in Europe.
Drivers should generally replace their cars' tires every six to 10 years, depending on manufacturing recommendations. Tread wear, exposure to outdoor elements and tire age are three factors to consider when questioning whether vehicle tires should be replaced.
To replace a transmission speed sensor, jack up the front of the vehicle, locate the speed sensor, remove the electrical plug, remove the speed sensor and replace with a new sensor. A faulty speed sensor causes the speedometer not to work.
An engine coolant temperature sensor needs replacing if the vehicle has trouble starting, black smoke comes out of the exhaust pipe or the vehicle consumes more gas than normal, according to CarsDirect. Leaking coolant and an overheating engine can also be signs of a defective coolant sensor.
To replace the vehicle's oxygen sensor, lift the car, locate the sensor, disconnect the sensor wire, remove the bolts that attach the sensor to the exhaust system, remove the old sensor, bolt the new sensor in the place, and reconnect the sensor wire. Lower the vehicle to complete this process.
To replace a cam sensor, first locate the cam sensor, which is located in a different spot depending on the engine. Remove the electrical plug, and undo the bolt securing the sensor. Twist the sensor to remove it, and then replace it with the new camshaft sensor.
The most important step in replacing a transmission pressure sensor is to identify it correctly. The tools required for the task include a wrench set, a socket set, a transmission gasket, transmission fluid and an oil pan.
The minimum required depth for tire tread is 1/16 of an inch. This becomes noticeable when the built-in tire wear indicator — the letters TWI and an arrow -- shows up in the tire tread.
Install a new ABS sensor by removing the old sensor first. This requires lifting the car enough to remove the wheel, locating the old sensor and removing the speed control actuator. Once the old sensor is removed, pull the old sensor free and replace it with a new one.
