Parts for your 2019 Mitsubishi Outlander-Throttle position sensors

2019 Mitsubishi Outlander Throttle Position Sensors

Technical sources confirm the 2019 Mitsubishi Outlander uses throttle position sensors (TPS) as part of its electronic throttle control. Mitsubishi workshop manuals for 2016–2020 Outlander models describe dual TPS units integrated into the throttle body (often labelled TPS1/TPS2) working with a throttle control motor. Factory wiring diagrams and OBD-II sections list TPS-related fault codes (such as P0120–P0124), and Mitsubishi parts catalogues show the TPS as part of the throttle body assembly rather than a stand-alone, serviceable sensor. This applies to the 2.0L/2.4L petrol engines and the PHEV variant.

The throttle position sensors on a 2019 Outlander tell the engine control unit exactly how far the throttle plate is open. Because the car runs drive-by-wire, there’s no physical cable from pedal to throttle—so the ECU compares the accelerator pedal position with the TPS signals and moves the throttle motor accordingly. The dual-sensor setup adds redundancy and accuracy, helping with smooth take-offs, steady idle, and clean gear changes, while keeping emissions and fuel use in check.

There isn’t a scheduled replacement interval for the TPS on this model, and the sensors aren’t generally serviced separately—the whole throttle body is replaced if a sensor fails. During regular servicing, good workshops:

• Scan for fault codes and check live data for TPS1/TPS2 agreement and smooth signal sweep.
• Inspect and, if needed, carefully clean the throttle body bore and plate using throttle-body-safe cleaner (ignition off, no forcing the plate).
• Perform an idle/throttle relearn with a scan tool after cleaning or battery work to keep the ECU’s adaptations tidy.

Common signs of TPS issues include erratic idle, hesitation, poor response, sudden limp mode, higher fuel use, and the check engine light. If testing shows a faulty sensor or mismatched TPS signals, replacement of the throttle body assembly is the go. A new gasket should be fitted, connectors checked for corrosion, and the harness secured properly. After installation, an electronic relearn is recommended so the ECU knows the new throttle’s closed and open positions.

As a preventive step, keeping the air filter fresh and the intake sealed helps reduce oil mist and grime on the throttle plate. Many techs like to inspect and, if needed, clean the throttle body around 60,000–100,000 kilometres, especially if the Outlander does lots of short trips or idles frequently. Look after the intake, and the TPS usually looks after itself.

Popular questions about 2019 Mitsubishi Outlander throttle position sensors

Does the 2019 Outlander have a separate, replaceable TPS?

No. On this model the TPS is built into the electronic throttle body. If the TPS fails testing, the typical repair is to replace the entire throttle body assembly, fit a new gasket, and carry out an idle/throttle relearn with a scan tool.

What fault codes point to a TPS problem on a 2019 Outlander?

Common TPS-related codes include P0120, P0121, P0122, P0123, and P0124. Workshops will also watch live data to see whether TPS1 and TPS2 track smoothly and agree with each other. If they don’t, the ECU may trigger limp mode to protect the engine.

Can cleaning the throttle body fix rough idle or hesitation?

Often, yes. Carbon and oil vapour can build up on the throttle plate, causing unstable airflow. A careful clean with throttle-body-safe cleaner (ignition off) followed by an idle relearn can restore a smooth idle and improve response, provided the sensors themselves are healthy.
