Parts for your 2013 Mitsubishi Outlander-Throttle position sensors

2013 Mitsubishi Outlander throttle position sensor (TPS): what it does and how to look after it

Referencing technical sources such as the Mitsubishi Motors service manual for the 2013 Outlander (GF/GM platform) and common workshop databases (e.g., Autodata/Mitchell/ALLDATA), this model uses electronic throttle control with a throttle body that contains dual throttle position sensors (TPS). It’s monitored by the ECU with OBD-II fault coverage (typical codes include P0120, P0122, P0123, P2135), so a throttle-position-sensor is relevant and fitted to the 2013 Outlander. On most petrol variants, the TPS is integrated into the throttle body and not sold separately.

The TPS tells the engine computer exactly how far the throttle plate is open, helping it manage fuelling, ignition timing, idle speed, gearbox shift strategy, cruise control and stability systems. Paired with the accelerator pedal position sensor, the TPS ensures snappy throttle response and smooth drivability. If the signals don’t align, the ECU can limit power to protect the engine and transmission, which is why a dodgy TPS often shows up as limp mode or a check engine light.

As part of routine servicing, the TPS itself isn’t a scheduled replacement item, but the throttle body deserves periodic attention. A light clean of the throttle bore and plate with throttle-body-safe cleaner every 60,000–90,000 kilometres helps prevent sticky operation that can confuse sensor readings. Don’t force the plate open with the ignition on, and avoid harsh solvents that can damage the sensor tracks or coating.

Diagnosis before parts: confirm fault codes and use live data to compare throttle command, TPS 1/TPS 2 agreement and accelerator pedal signals. Check the 5 V reference, earth and connector pins for corrosion under the bonnet—wiring faults are common. If the sensor has failed internally, replacement of the complete throttle body is usually required on the 2013 Outlander. Fit a new gasket, reconnect carefully, and carry out throttle/idle relearn using a scan tool. Many workshops also complete an idle stabilisation routine after battery disconnect.

Handy pointers for owners and techs:

• Typical symptoms: erratic idle, hesitation off the line, poor fuel economy, cruise control drop-out, or limp mode with a warning lamp.
• Aftermarket units vary—OE or reputable brands tend to calibrate more consistently.
• Good battery voltage and clean grounds help keep throttle control stable.

Popular questions about 2013 Mitsubishi Outlander throttle-position-sensors

Does the 2013 Outlander have a separate TPS I can replace?
On most petrol models, the TPS is built into the electronic throttle body as dual tracks, so it’s not sold as a stand-alone sensor. If the TPS fails, the usual fix is replacing the entire throttle body assembly and performing a throttle/idle relearn.

Is programming needed after replacing the throttle body?
Yes. The ECU needs to learn the new throttle plate positions. A proper adaptation or idle relearn via a scan tool is best practice. Many workshops also complete an idle stabilisation routine so it idles smoothly with and without A/C load.

What fault codes point to a TPS problem on a 2013 Outlander?
Common codes include P0120, P0122, P0123 and P2135. You might also see accelerator pedal codes (e.g., P2122/P2127). Always compare TPS 1 and TPS 2 agreement and inspect wiring before condemning the throttle body.
