How to Troubleshoot Issues With Your Turbo Accessories

If your vehicle isn't getting the boost you want, you may be having issues with the boost sensor or some other turbo accessories. You need to figure out what's happening and repair the issue. Let these tips help you with that process.  

Check the Vacuum Line

In some cases, the boost sensor may be fine, but the vacuum lines may not be working. Visually examine them. They should be flexible and intact. If they are brittle or broken, they need to be replaced. Also, look for leaks; that is another sign that the issue is with your vacuum tubes.

Look for Other Leaks

Leaks don't just appear in the vacuum lines. In some cases, there may be leaks in the other connectors running from your engine to your turbo accessories. Manually check that your connectors are sealed properly. To be on the safe side, you may want to take your vehicle in to a mechanic who has experience with turbo accessories. They can do a smoke test to look for leaks.

Check the Turbo Wheel

In some cases, the turbo itself may be the issue. If possible, remove the downpipe so that you can access the turbo. Then, try to spin it by hand. If it doesn't spin or if it's overly loose, it needs to be repaired or replaced.

Remove and Clean the Boost Sensor

The boost sensor is a small part, but if it's blocked, that may be impeding your system. To remove it, take off your engine cover first, and then, find the boost sensor. Luckily, this part is usually held on by just a single electrical connector and a bolt. Remove the bolt first. Then take off the electrical connector. You may need to use a screwdriver to pry it loose.

When you have removed the boost sensor, spray it with a cleaning product and wipe it dry. Use a white cloth and repeat until the cloth comes away from the boost sensor clean. Be careful of the little needle. You don't want to accidentally scrub so hard that you break that part. Once everything is clean, reattach the boost sensor. Typically, it works best to do it in the reverse order. Reconnect the electrical connector and tighten the bolt to hold it in place.

These steps should help you figure out what's happening with your turbo system. If you can't find the issue, bring your vehicle in to a specialist.
