Troubleshooting a Tire Pressure Gauge that Won’t Read and Hold Pressure

Manufacturers construct tire pressure gauges to withstand fall, especially if the device is for mechanical and professional use. Likewise, high-quality tire pressure gauges have a high level of accuracy and a long lifespan. And there are little chances that something might go wrong with the device, particularly if it is new.

Unfortunately, there are instances wherein a tire pressure gauge could no longer read and hold pressure. If your tire pressure gauge has this problem, worry not! Below are some tips to help you troubleshoot your tire pressure gauge.

When the Tire Pressure Gauge Won’t Read

If the device could no longer read, the problem is on the gauge’s stem. It means the stem won’t pop up or back in. This problem is only apparent in mechanical tire pressure gauges.

To fix a mechanical tire pressure gauge with a stem stuck out, the first thing you have to do is perform the manual repair. The stem is usually jammed against the side, which prevents it from popping back in and out. Gently wiggle the stem to move. If the stem won’t budge, try gently pulling the stem then releasing it. It will help the stem to slide back.

If the stem is still stuck and won’t release, apply a lubricant on the stem tube, like a WD-40. It will help to soften the rust or any debris that accumulated on the stem. After applying the lubricant, scrape out the dirt, rust, or grease to free the stem, and then, try wiggling it and pull the stem gently.

For cases wherein the stem won’t pop out, chances are the device’s spring is broken. If the spring is the issue, you can either replace the spring or buy a new one. It is easier to replace a tire pressure gauge rather than looking for the correct spring. Likewise, it is cheaper to buy a new gauge than purchasing a hard-to-find spring.

For digital tire gauges, it is best to buy a new one if the device no longer reads pressure.

When the Tire Pressure Gauge No Longer Holds Pressure

Occasionally, it can happen when there is dirt, dust, greases, or rust collected on the valve seat. To fix this, unscrew the tire gauge stem, and then pull out the brass plug. While doing this, check if the o-ring is aligned.

Tap the valve seat and spring, and gently blow down the stem while pressing the bleed button. Once fixed, reassemble the gauge.

If the problem remains, the bleed stem might be stuck or broken. Use lubricating oil and squirt it down the bleed button to solve the issue.
