# Adjusting Parking Sensors
## How to adjust parking sensors for aftermarket compatibility on Sprinter Vans.
**Ladder + Tire Carrier Sensor Issue**
A few of our customers have reached out regarding pinging of the backup sensors when reversing after Ladder + Tire Carrier installation. While most vans should not have this issue, a small number of vans do. As best we can tell, this is due to the installation of the parking sensor being “aimed” differently. Most customers with the issue have been able to reach up behind the flexible plastic bumper, adjust (fiddle with) the sensor closest to the ladder, and aim it slightly away from the ladder. This solution has worked for most customers. Suppose you’re still having the problem; try unscrewing the bottom footpeg, and see if the issue goes away. If the issue goes away, we can try shortening the footpeg. Feel free to trim your footpeg down on your own (hacksaw or bandsaw). If you need us to ship you a shorter one, we can also do that.
**After installing a carrier my backup sensors are going off?**
While the vast majority of vans do not have any sensor pinging when reversing, some vans do experience issues. There are a couple of options. You can turn off the sensors from the media touch screen in the van (top left). If you prefer a more long term solution you can adjust the bumper cover or tilt the sensor. Tilting the sensor is quick and easy.
Each bumper sensor has a clip top and bottom holding it in. Work you hand up to one of the sensors. Unclip the bottom clip while pushing in on the bottom of the sensor face. The sensor should tilt slightly (see picture). You only need to tilt the sensor a VERY small amount. Our suggestion is tilt the sensor slightly, check to see if it pings. Repeat until it is tilted enough to stop pinging and you’re pretty much done. The snug fit of the sensor means it should stay put. If you want to secure it more you can put a drop of RTV (silicon gasket maker) joining the sensor to the housing. When the RTV drys it will hold the sensor securely but can be removed should you ever need to remove the sensor.
