Parts for your 2019 Ford Mondeo-Throttle position sensors

2019 Ford Mondeo throttle-position-sensors

Based on Ford workshop literature (Ford ETIS/Motorcraft Service), Autodata/HaynesPro, and OEM parts catalogues for the 2015–2019 Mondeo (CD391), the 2019 Ford Mondeo uses an electronic throttle body on EcoBoost petrol engines with dual-track throttle position sensors integrated into the unit. Diesel variants employ an intake throttle/air doser with a position sensor for EGR control and smooth shutdown. So yes—this model absolutely relies on throttle-position-sensor feedback for engine and driveline management.

The throttle-position-sensor (TPS) tells the powertrain control module exactly how far the throttle plate is open. On the Mondeo’s drive-by-wire setup it’s a redundant, dual-signal arrangement designed for safety and accuracy. The PCM blends TPS data with the accelerator pedal position, mass airflow/boost data and engine speed to manage fuelling, spark timing, idle control, cruise, and even transmission shift behaviour. That’s why a healthy TPS is crucial for smooth take-offs, consistent power, good economy, and clean emissions.

There’s no fixed replacement interval for the TPS on a 2019 Mondeo, it’s serviced on condition. Because the sensor is built into the throttle body (and into the intake throttle on diesels), most faults are resolved by replacing the complete assembly rather than the sensor alone. During regular servicing, a technician should:

• Scan for relevant DTCs (common codes include P0120–P0124, P0220–P0229, and throttle actuator codes like P2100–P2112).
• Check live data for smooth, matching throttle and pedal position signals with no dead spots or spikes.
• Inspect the throttle body for carbon build-up, clean the bore and plate with appropriate throttle-body cleaner without soaking the electronics.
• Verify connector fitment and harness condition—look for corrosion or chafing near the throttle body.
• Perform a throttle adaptation/relearn after cleaning or replacement using a scan tool or the specified key-on/idle procedure from Ford service information.

Drivers might notice symptoms such as erratic idle, hesitation, poor fuel economy, cruise control dropping out, harsh shifts, or the wrench/engine light and limp-home mode if the TPS signal isn’t right. If tests confirm a faulty sensor, fitting a genuine or quality OE-equivalent throttle body, replacing any gaskets, and completing the PCM relearn usually restores proper operation. It’s a tidy, sub-1-hour job for most workshops. A quick road test with live data afterwards ensures the readings are linear and the engine responds crisply across the rev range—exactly how a well-sorted Mondeo should feel across Aussie and Kiwi roads.

Popular questions about 2019 Ford Mondeo throttle-position-sensors

Does the 2019 Mondeo have a separate TPS, or is it built into the throttle body?
On the 2019 Mondeo the TPS is integrated into the electronic throttle body on petrol models and into the intake throttle/air doser on diesel variants. It uses dual tracks for redundancy. If the TPS fails, the fix is typically to replace the complete throttle unit rather than the sensor alone.

What are the common signs the TPS is playing up on a 2019 Mondeo?
Typical clues include an unstable idle, hesitation, flat spots, cruise control cutting out, unexpected limp-home, and fault codes like P0121 or P0220. A scan-tool check of live throttle and pedal data will show if the signal is noisy or inconsistent.

Do you need to recalibrate the throttle after cleaning or replacing it?
Yes. After cleaning carbon build-up or fitting a new throttle body, a throttle adaptation/relearn should be done. A proper scan-tool routine is best, though some workshops follow the Ford-specified key-on/idle procedure. Skipping this step can leave the idle and tip-in feel a bit off.
