RV tyre pressure monitor with four sensors

The WUQ M12-3 system monitors pressure from zero to 87 PSI across four wheels. A solar panel on the display unit keeps the internal battery topped up, with AC or DC charging as a backup. It is aimed at RV owners and trailer drivers who want continuous pressure data without frequent cable charging.

Upgrade from basic warning lights

Factory low-pressure lights only trigger after a large drop. This kit adds high-pressure, high-temperature, rapid-leak and sensor-battery alerts with user-set thresholds at plus 25 per cent and minus 15 per cent of the reference pressure. The jump is worth it when you need early warning on heavy loads or long highway stretches.

Fits a tow-vehicle dashboard

The display mounts on the dash and pairs with four external sensors that screw onto valve stems. Sensors swap positions in the menu without physical reinstallation when tyres are rotated. Auto sleep activates after 10 minutes of no motion and wakes on vibration, reducing battery drain during stops.

Questions about this item

What size valve stems do the four external sensors screw onto?

The sensors are standard external units that thread onto typical Schrader valve stems found on most car, trailer and RV wheels.

How do I pair each sensor to its wheel position on the M12-3 monitor, and what is the common mistake?

Install sensors one at a time; the monitor automatically sets the current pressure as the reference value. The common mistake is fitting all four sensors before pairing, which prevents the system from learning each position.

When will the four sensors need replacement, and what indicates a dying sensor battery?

Sensors have a maximum working life of 2 years. A dedicated low-battery alarm on the monitor warns when a sensor battery is running low.
