Parts for your 2024 Mitsubishi Eclipse cross-Throttle position sensors

2024 Mitsubishi Eclipse Cross throttle-position-sensors: what’s fitted and how they’re serviced

Based on technical sources, the 2024 Mitsubishi Eclipse Cross does use throttle position sensing, but it’s built into the electronic throttle body rather than a separate bolt-on sensor. Mitsubishi’s Eclipse Cross service information for the GK/GL series (covering the current shape) describes an Electronic Throttle Control system with a throttle control motor and dual throttle position sensors inside the throttle body, providing redundant signals to the engine ECU. The Mitsubishi parts catalogue lists a complete “throttle body assembly” (motor and sensors together) with no standalone TPS part. The factory DTC list also includes throttle-position-related codes (such as P0121–P0123, P2135), confirming the system’s presence and how it’s monitored.

On the 2024 Eclipse Cross, the throttle-position-sensors tell the ECU exactly how far the throttle plate is open. With two independent sensor tracks, the ECU cross-checks the readings to keep the engine smooth, the idle tidy, and the turbo’d 1.5-litre happily responsive. Because it’s a sealed electronic throttle body, there’s no routine TPS replacement on the service schedule. Instead, good servicing focuses on keeping the air path clean and ensuring the electronics see stable voltage.

Practical care under the bonnet looks like this:

• Air filtration and cleanliness: Fit quality air filters on time and keep the intake plumbing sealed so dust doesn’t chew out the throttle shaft area.
• Throttle body cleaning: If idle gets rough or gummy deposits are visible, a careful clean of the throttle bore can help. Don’t flood the unit or force the butterfly by hand, use throttle-safe cleaner in light bursts and a lint-free cloth.
• Battery health: Low voltage causes erratic throttle readings. A strong battery and clean terminals keep the sensors happy.
• Relearns and diagnostics: After cleaning, battery disconnection, or throttle body replacement, a scan-tool idle/throttle relearn is recommended. If the check engine light pops with TPS codes (P0121–P0123, P2135), proper diagnosis is key before parts are swapped.

Replacement is straightforward but typically involves swapping the complete throttle body assembly, fitting a new gasket, torquing to spec from the service manual, and performing a relearn procedure. Symptoms that suggest attention include hesitant acceleration, hunting idle, sudden limp-home, or higher-than-usual fuel use across the kilometres. For most owners, the unit should last many years, regular servicing and clean air are the big helpers.

Popular questions

Does the 2024 Eclipse Cross have a separate throttle position sensor I can replace?
No. It uses an electronic throttle body with the TPS built in. If the sensor fails, the fix is usually to replace the complete throttle body assembly and carry out a throttle/idle relearn with a scan tool.

How long should the throttle body and its sensors last?
With clean air and stable battery voltage, many will run well past 150,000 km. Issues tend to show up as fault codes, limp mode, or erratic idle—signs it’s time for testing and, if needed, replacement.

Will cleaning the throttle body clear TPS-related fault codes?
If deposits were the problem, a careful clean can help drivability. But sensor circuit or correlation faults often need proper diagnosis and sometimes a new throttle body plus a relearn. Don’t skip the scan-tool steps.
