Parts for your 2016 Mitsubishi Asx-Throttle position sensors

Throttle Position Sensor on the 2016 Mitsubishi ASX

Technical sources confirm the 2016 Mitsubishi ASX does use a throttle position sensor, and it’s built into the electronic throttle body. Mitsubishi’s ASX/RVR/Outlander Sport service manual (2015–2017, Group 13A – Multiport Fuel Injection) describes the throttle body assembly as including the throttle control motor and dual throttle position sensors. Mitsubishi OBD references also list TPS-related diagnostic trouble codes for this model (e.g., P0120, P0220, P2135), and the Mitsubishi ASA parts catalogue shows throttle body assemblies with integrated TPS for the 4B11 2.0 petrol and 4N14 2.2 diesel engines.

On the 2016 ASX, the throttle position sensors tell the engine control unit exactly how far the throttle plate is open, so fuelling and ignition can be tweaked on the fly. Working alongside the accelerator pedal position sensor, the TPS is central to smooth throttle response, decent fuel economy, and clean emissions. Because the sensors are part of a drive-by-wire system, they’re built with redundancy (two tracks) for safety and accuracy.

There’s no scheduled replacement for the TPS on this model, it’s effectively maintenance-free. However, keeping the throttle body clean and the air filter fresh helps protect the sensors from contamination. If drivability goes off—think erratic idle, hesitation, flat spots, sudden limp mode, or the MIL lighting up—fault codes may point to the TPS circuit. In practice, the TPS isn’t a separate service item on most 2016 ASX variants, replacement typically means swapping the complete throttle body assembly.

• Common symptoms of TPS issues:
  • Check engine light with TPS codes (P0120/P0220/P2135)
  • Idle hunting or stalling when coming to a stop
  • Poor throttle response or harsh kick-down
  • Reduced power mode
• Good servicing habits:
  • Inspect the throttle body and connector at major services (30–40,000 km)
  • Clean the throttle plate using approved throttle cleaner, avoid forcing the plate by hand
  • Check loom routing and grounds under the bonnet for corrosion or chafing
  • After cleaning or replacement, carry out a throttle/idle relearn with a scan tool, where a scan tool isn’t available, follow the OEM warm-up and idle stabilisation procedure

When replacement is necessary, owners should opt for quality OEM-equivalent throttle body assemblies, fit a new gasket, torque fasteners correctly, and complete the adaptation procedure so idle and tip-in feel are spot on. Done right, the ASX’s throttle position sensors will keep things smooth and economical across Kiwi and Aussie roads.

Popular questions about 2016 Mitsubishi ASX throttle position sensors

Does the 2016 ASX actually have a throttle position sensor?
The 2016 ASX does have throttle position sensors, integrated into the electronic throttle body. Both the 2.0 petrol and the 2.2 diesel use this drive-by-wire setup with dual TPS tracks for redundancy and accuracy.

Can the TPS be replaced on its own, or is it part of the throttle body?
On most 2016 ASX models the TPS isn’t sold separately, it’s part of the throttle body assembly. If the sensor fails or the tracks go out of range, technicians usually replace the complete throttle body, then perform a throttle/idle relearn.

How is the throttle relearn done after cleaning or replacement?
The best method is using a capable scan tool to run the throttle/idle initialisation routine as specified by Mitsubishi. Without a scan tool, a basic relearn can be attempted by warming the engine fully, cycling ignition on for around 30 seconds, then idling with all loads off for several minutes. Following the factory procedure is recommended for stable results.
