Reset the Tyre Pressure Monitoring System

Last updated: May 17, 2026

The second-generation Ford Focus (C307 chassis, 2004–2012) was offered with a Tyre Pressure Monitoring System on Titanium, Ghia, and ST trims from the 2008 facelift onwards. The system is indirect — pressure is inferred from ABS wheel-speed asymmetry rather than measured by valve-stem sensors. After adjusting tyre pressures, rotating wheels, or replacing tyres, the system must be reset so it knows the new pressures are the new baseline. The reset uses the wiper-stalk-mounted information display navigation, with no scan tool required.

Before you start

The Mk2 Focus’s indirect TPMS reads each wheel’s rotational speed from the ABS sensor and compares them. A low-pressure tyre rolls slightly faster than its full-pressure neighbours; the algorithm catches a drop of around 25% (a 7 psi / 0.5 bar drop in standard summer tyres). The reset tells the system “treat the current pressures as the new correct baseline.”

• Check all four tyres cold. The car should have been stationary for 3+ hours or driven under 1 km. Warm tyres read higher than their cold value and skew the baseline.
• Use the door-jamb placard pressures. The Mk2 Focus placard is on the driver’s door pillar, typically showing 2.2 bar / 32 psi all round for standard tyres (195/65 R15, 205/55 R16, 215/45 R17 on ST). Higher loads may need 0.2 bar more in the rear.
• Use an accurate gauge. A £15 dial gauge or a £25 digital gauge is far more reliable than forecourt machines.
• Don’t reset before re-inflating — that would baseline the system on the under-inflated state and you’d never see the warning return.

Tools required

• Accurate tyre pressure gauge
• Air compressor (or forecourt with a checked gauge)

When to reset the TPMS

• After checking or adjusting any of the four tyres’ pressures.
• After replacing one or more tyres.
• After changing wheels (seasonal swap to winter rims, etc.).
• After a wheel alignment or rotation.

Reset procedure

1. Inflate all four tyres cold to the placard pressures, verified with your own gauge.
2. Switch the ignition ON without starting the engine (key to position II).
3. Use the wiper-stalk control to navigate the information display. The Mk2 Focus’s information display sits between the speedometer and tachometer. The wiper stalk’s lower button (sometimes labelled INFO or with arrow icons) cycles through menus.
4. Select the menu option labelled SET. Some trim variants display “SETTINGS”; the action is the same.
5. Scroll within the SET menu until “Tyre Pressure” (or “Tire Pressure” on some US-spec readouts) is shown.
6. Press and hold the SEL/RESET button on the wiper stalk. The button is usually marked with a checkmark or “OK” symbol.
7. Continue holding until the display shows “Tyre Pressure Set” (or “Tire Pressure Set”). This typically takes 2–3 seconds of held button.
8. Release the button. The TPMS baseline is now set to the current pressures.
9. Start the engine and drive normally for at least 10 minutes at over 30 km/h. The TPMS algorithm needs a baseline drive to confirm the new pressures across all four wheels.

How to verify it has worked

• The TPMS warning light (exclamation mark inside a horseshoe-shaped tyre cross-section) is no longer illuminated.
• No “Check tyre pressures” message in the message-centre display.
• The information-display sequence shows “Tyre Pressure Set” confirmation immediately after the SEL/RESET hold.
• A 10-minute drive after the reset doesn’t bring the warning back.

Troubleshooting

“Tyre Pressure” menu doesn’t appear under SET. Your trim variant may not have TPMS — only Titanium, Ghia, and ST cars from 2008 onwards had it as standard. Cars without the option don’t have the menu item. Conversely, some lower-trim cars from late 2010 production did include the menu but with the option deactivated; a scan-tool activation step (via Ford IDS or FORScan) enables it.

SEL/RESET button doesn’t trigger the reset. Most common cause on a 10+ year old car: the wiper stalk’s switch contacts are worn. Try pressing more firmly, slightly off-centre. If still no response, the stalk needs replacement (around £40 for the part, 15 minutes to fit).

Reset completes but light returns after 10 minutes of driving. One or more tyres is still under-inflated. Recheck all four with your own gauge, cold; even a small deviation can keep the warning active. Look for slow leaks at valves, beads, and tread.

“Tyre Pressure Sensor Fault” message appears. This is unusual on the Mk2 Focus’s indirect TPMS — it suggests one of the four ABS wheel-speed sensors is reporting inconsistent data, not that a valve-stem sensor has failed. Scan the ABS module with a Ford-aware tool (FORScan free version handles this).

Light flashes for 60 seconds at every start, then stays on. Different fault: the TPMS module has a stored “system fault” code. Indicates an internal module problem; needs Ford diagnostic equipment to clear, and possibly replacement of the module if the code persists.

Frequently asked questions

Does the Mk2 Focus have direct or indirect TPMS?
Almost all EU-spec Mk2 Focus cars have indirect TPMS (no valve-stem sensors). Some US-market 2008–2012 cars have direct TPMS with valve-stem transmitters; those use a different reset procedure (a dedicated TPMS button on the dashboard, hold for 3 seconds). If you can see per-wheel pressure values in the message-centre, you have direct; if you only see a single warning lamp and no values, you have indirect.

How long do indirect TPMS systems last?
Indirect TPMS uses the ABS wheel-speed sensors that the car already has — there’s no separate battery to fail. The system lasts the life of the ABS sensors themselves, typically 200,000+ km.

Will cold weather cause false warnings on the Mk2 Focus TPMS?
Yes. Tyre pressure drops about 0.1 bar per 10 °C cool-down. The first cold morning of autumn often triggers the warning on cars set to summer placard pressures. Top up to placard and reset.

Why does the Mk2 Focus ST have the same procedure as the standard Focus?
The ST uses the same body control module and TPMS algorithm as the standard Mk2 — only the ABS module differs (uprated for the ST’s higher performance). The TPMS reset is independent of the ABS module variant.

I have an aftermarket head unit — does it interfere?
No. The TPMS reset is owned by the cluster and the wiper stalk; the head unit is on a separate bus. Aftermarket head units don’t affect this reset.

Will the procedure work on the Mk2 Focus Estate (wagon)?
Yes — same procedure, same buttons. The Estate adds rear-load-sensing pressure suggestions (higher rear pressures recommended when carrying heavy loads), but the TPMS reset is identical.
