Where is the speed sensor on a 2000 Nissan Maxima?
The speed sensor is on the bottom of the steering knuckle.
How do I test my VSS signal?
Connect the VSS to a power drill so you can simulate the rotation of the vehicle’s transmission and read the multimeter to see if the voltage increases as the speed increases to check if the sensor is working properly.
What does automatic transmission speed sensor do?
A transmission speed sensor calculates the transmission gear ratio when in use. A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car’s powertrain module. The ISS sensor monitors the input shaft’s speed.
How do I fix code P0720?
What repairs can fix the P0720 code?
- Replacement of the output speed sensor.
- Replacement of the input speed sensor.
- Replacement of the wires or connectors.
- Drain and refill of the transmission fluid.
- Replacement of the PCM.
Which speed sensor controls speedometer?
The speed sensor is a small device that tells your car’s speedometer how fast you’re going. It plays a role in your car’s transmission and cruise control systems.
What happens if I disconnect the speed sensor?
If it’s the wheel speed sensors (like for the ABS) the car will run but the ABS system won’t be able to do its job. If we’re talking about any engine sensors, the engine MIGHT still run, but it will likely run poorly or throw a check engine light.
Can you drive with a P0720?
In most cases the P0720 code does not keep a car from being drivable. However, the effects of the code can get worse if it is not repaired, and further damage can be caused to the transmission.
What causes code P0720?
If your vehicle is showing code P0720, this indicates a problem with your output speed sensor circuit. This means that your vehicle’s computer has sensed a problem with the sensor that helps it control the way the vehicle shifts gears.
How much does a VSS cost?
The average cost for vehicle speed sensor replacement is between $256 and $301. Labor costs are estimated between $107 and $135 while parts are priced between $149 and $166. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How do you fix a speed sensor circuit malfunction?
How much does it cost to fix a P0720?
How much will it cost to fix the problem? Costs vary depending upon the cause of the P0720 code. For example, draining and replacing transmission fluid professionally generally costs between $240-290. On the other hand, replacing an output speed sensor will likely cost somewhere between $330-380.
