How Do You Reset the Volvo V40 TPMS?
If your Volvo V40 tire pressure warning light is on, check and adjust each tire’s inflation pressure before following the Volvo low tire pressure warning reset procedure.
2012-2019 Volvo V40 TPMS Reset Procedure
With the engine running, press the MY CAR button underneath the Volvo V40 dashboard display screen.
Press the MENU/OK button.
Scroll down and select TYRE MONITOR by pressing the OK button.
Select CALIBRATE TYRE PRESSURE.
A message will appear “Calibration initiated, may take several minutes of driving. OK to confirm. EXIT to cancel.”
Press the OK button.
Drive the Volvo V40 for 5-10 minutes at speed exceeding 25 Mph.
What Sets Off Your Volvo V40 Tire Pressure Monitoring System?
Major Pressure Changes: Deviating significantly from Volvo V40 recommended tire pressure reference values can activate the low tire warning light.
Temperature Fluctuations: Changes in external temperature may expand or contract tire air, triggering the TPMS warning.
Tire Damage: Punctures, cuts, or tread wear leading to air loss can set off the TPM alert.
Poor Maintenance: Neglecting regular tire pressure checks and adjustments can prompt a low tire warning.
Mismatched Tires: Using tires of different sizes or types than Volvo recommends for the V40 can cause TPMS inaccuracies and tire light activation.
Calibration Issues: The Volvo V40 TPMS needs recalibration after tire changes or rotations. Incorrect recalibration can lead to false tire pressure warnings.
How Does the Volvo V40 Tire Pressure Monitoring System Work?
Instead of tire pressure sensors, the Volvo V40 tire pressure monitoring system uses wheel speed sensors, part of its ABS, to measure and monitor tire pressure. This is called an indirect TPMS.
Wheel Speed Sensors: These are crucial components of the ABS, positioned behind each wheel or within the wheel hub, tasked with measuring the speed of each wheel.
Identifying Low Tire Pressure: When a tire’s air pressure is low, it rotates faster compared to tires that are correctly inflated. The Volvo V40 TPMS utilizes the variation in wheel speeds to deduce the inflation pressure of the tires.
Low Tire Pressure Warning Light: A significantly higher rotation speed of any tire, signaling reduced air pressure, prompts the tire pressure system to issue a low tire warning to the driver. The Volvo V40 dashboard display will read “tyre pressure low Check, adjust and calibrate” as well as the standard orange tire pressure light.
System Reset Post-Inflation: After adjusting the tire pressure to the appropriate level, the Volvo V40 TPMS requires a reset to ensure it continues to deliver precise readings.
Common Volvo V40 Tire Pressure System Problems
Inaccurate Alerts: Incorrect low pressure warnings due to wheel speed data errors or ABS sensor faults.
TPMS Calibration: Problems from not recalibrating the Volvo V40 TPMS after tire changes or adjustments.
Temperature Effects: Air pressure misreadings caused by significant temperature shifts affecting tire air density.
Wear and Damage Detection: The tire pressure system’s inability to detect issues in severely worn or damaged tires.
Mismatched Tires: Incorrect alerts from using tires of different sizes or types than Volvo requires.
Software Issues: Glitches requiring updates or resets for accurate functioning.
Driving Dynamics: Misinterpretations from rapid accelerations or high-speed driving.
Uneven Tire Changes: Misleading warnings after replacing or repairing only one tire.
Aftermarket Wheels: Compatibility issues affecting accuracy with non-original wheels.
Not Driving: For the Volvo V40 tire pressure monitoring system to function, the vehicle must be driven.
Why is My Volvo V40 Low Tire Pressure Light On When the Tires are Fine?
The Volvo V40 tire pressure light might turn on even when tires appear fine and match the door’s tire pressure reference pressures. This issue often stems from using different brands or sizes of tires or from uneven tire wear. The Volvo indirect TPMS can trigger a low tire pressure warning due to small differences in tire size or brand. To prevent this, ensure all four tires are uniform in size, brand, make, model, and tread wear.
What to Do if the Volvo Low Tire Pressure Warning Reset Does Not Work?
If the Volvo V40 TPMS warning stays on after setting the tire pressures correctly, recalibrate the system. Ensure air pressures match the exact driver’s door panel tire pressure reference values, then proceed with the Volvo V40 TPMS recalibration. If unsuccessful, deflate each tire by 10 psi, re-inflate, drive for 5-10 minutes, and retry the tire pressure reset. It may require multiple attempts.
A persistent TPMS light could indicate a wheel speed sensor or computer system malfunction.

Volvo V40 FAQ
Can the Volvo V40 TPMS Be Disabled?
The Volvo V40 tire pressure monitoring system cannot be disabled.
Is it Safe to drive with Low Tire Pressure Light On?
It’s advised not to drive if the low tire pressure warning light is on. If the Volvo V40 tire light activates, safely stop and use a digital tire pressure gauge to check the air pressure in each tire, while also visually examining the tires and wheels for any abnormalities.
Will a Change in Weather Trigger the Volvo Low Tire Pressure Warning?
Yes, changes in air temperature can activate the Volvo’s low tire pressure alert. To prevent this, make sure to regularly check and adjust the tire pressure when the tires are cold.
How Far Can You Drive With the TPMS Light On?
There is no safe duration or distance for driving the Volvo V40 when the low tire pressure light is illuminated. It’s advisable to address and rectify the reason for the alert before proceeding to drive.
What Happens If a Wheel Speed Sensor Stops Working?
If a Volvo V40 wheel speed sensor malfunctions, the dashboard will display warning lights for tire pressure, ABS, and traction control.
