Parts for your 2013 Mitsubishi Lancer-Throttle position sensors

2013 Mitsubishi Lancer throttle-position-sensors (TPS)

Technical sources confirm the 2013 Mitsubishi Lancer does use throttle-position sensors. The model’s electronic throttle body houses dual TPS elements (main and sub) that the engine control module (ECM) reads to manage throttle plate angle. This configuration is documented in: Mitsubishi Lancer (CY/CX) 2008–2015 Factory Service Manual – Engine Control (Electronic Throttle Control/Throttle Body), Mitsubishi ASA/OEM parts catalogues describing the throttle body assembly with integrated position sensors and actuator, and the vehicle’s diagnostic coverage, which includes OBD-II DTCs P0121–P0123 and P2135 for throttle/pedal position sensor circuits. Together, these sources show the TPS is integral to the Lancer’s drive-by-wire system and not a separate, stand-alone part.

On a 2013 Lancer, the throttle-position-sensors live inside the throttle body and constantly report how far the throttle plate is open. The ECM compares the twin sensor signals for accuracy, then decides how much to open the plate via the built-in throttle motor. That’s how the car delivers smooth response, stable idle and decent fuel economy without a traditional cable. Because the sensors are built in, most genuine repairs involve the complete throttle body rather than a separate TPS, and a throttle relearn is needed after any replacement or battery disconnect.

As part of regular servicing, it’s smart to keep an eye on the throttle body and its connectors. A gentle clean of the throttle bore (engine off, battery disconnected) with the correct throttle-safe cleaner can help prevent sticky operation. Don’t force the throttle plate open by hand and avoid soaking the electronics. After cleaning or replacement, a throttle/idle relearn using a scan tool (or the specified warm-up/idle procedure from the factory manual) helps the ECM settle into the correct baseline.

If the TPS signals disagree or drift, the car may drop into limp mode and log fault codes. Common clues include erratic idle, hesitation, poor fuel economy, cruise control dropping out, or the check engine light with codes like P0121, P0122, P0123 or P2135. Wiring and connector issues are just as common as a worn sensor track, so a proper diagnosis is worth the effort before parts are swapped.

• Typical TPS-related symptoms: unstable idle, flat spots on acceleration, harsh shifts (auto), and reduced power mode.
• Service tips: inspect the harness at the throttle body, check for oil ingress or corrosion at the connector, verify grounds and battery health, then perform a relearn after any work.

While some aftermarket vendors offer separate sensors, the Lancer’s OEM design treats the TPS as part of the throttle body assembly. Using quality parts and following the relearn procedure keeps the throttle happy and the kilometres rolling without dramas.

FAQs

Does a 2013 Mitsubishi Lancer have a throttle position sensor?
Yes. It uses dual throttle-position-sensors integrated into the electronic throttle body. The ECM reads both for accuracy and failsafe operation.

Can the TPS be replaced separately from the throttle body?
From the factory, it’s supplied as part of the throttle body assembly. Some aftermarket options claim stand-alone TPS replacements, but correct fitment, calibration and reliability can vary, and a throttle relearn will still be needed.

What are the signs the TPS is failing, and is it safe to drive?
Look for erratic idle, hesitation, poor fuel use, or limp mode with DTCs like P0121–P0123/P2135. It may be driveable, but reduced power can be unsafe, get it checked and repaired promptly.
