Parts for your 2016 Mitsubishi Lancer-Throttle position sensors

2016 Mitsubishi Lancer throttle position sensors (TPS) – what they do and how to look after them

Based on the factory Mitsubishi Lancer (2016 MY) Service Manual (Engine – Multiport Fuel Injection: Electronic Throttle Control) and common repair databases such as Mitchell 1/ProDemand and ALLDATA, the 2016 Mitsubishi Lancer does use throttle position sensors. They’re built into the electronic throttle body as dual TPS tracks alongside the throttle control motor, and they’re not serviced separately. The manuals also list related DTCs (e.g., P0120–P0124, P0220–P0223), confirming the ECU monitors TPS signals. In parts catalogues (e.g., Mitsubishi ASA), the TPS isn’t listed as a standalone part—replacement is via the complete throttle body assembly.

On a 2016 Lancer, the throttle position sensors tell the ECU exactly how far the throttle plate is open. The ECU cross-checks these signals against the accelerator pedal position sensors and other inputs to deliver smooth throttle response, stable idle, and proper fuel and spark. With modern drive-by-wire, accuracy is everything—so Mitsubishi uses two TPS signals for redundancy and safety.

What owners typically notice when the TPS inside the throttle body goes out of whack: erratic idle, hesitation off the line, poor fuel economy, the MIL on, or limp-home mode. Fault codes for TPS correlation or range/performance are common clues. Because the sensors are integrated, the usual remedy is replacing the throttle body assembly rather than just the sensor.

Good servicing habits help. Under the bonnet, a gentle throttle body clean (using proper throttle-safe cleaner) can clear sticky deposits that mimic TPS issues. Don’t flood the unit—short bursts and a lint-free cloth are the go. Check the throttle body electrical connector for moisture or green crusties, and make sure the loom isn’t chafed near the intake. After cleaning or replacement, an idle/throttle relearn may be needed. Many scan tools offer a throttle relearn function, otherwise follow the factory warm-up and idle stabilisation procedure so the ECU can re-adapt. If the throttle body is replaced, fit a new gasket, torque fasteners correctly, and clear codes before road-testing.

If a TPS-related code pops up, it’s worth doing a proper diagnosis first: battery/charging health, intake air leaks, connector pin tension, and pedal sensor signals. Replacing the whole throttle body is straightforward with the right tools, but if in doubt, a qualified tech will save a lot of head-scratching and keep the Lancer running sweet for many more kilometres.

• Typical symptoms: rough idle, surge/hesitation, MIL on, limp mode.
• Typical fixes: clean throttle body, repair wiring, throttle body replacement, ECU relearn.

FAQs

Does a 2016 Mitsubishi Lancer have a throttle position sensor?
Yes. The 2016 Lancer uses an electronic throttle body with two built-in throttle position sensors. They feed the ECU with throttle plate angle data for accurate drive-by-wire control.

Can the TPS be replaced separately on a 2016 Lancer?
No. The TPS is integrated into the throttle body with the throttle control motor. If the sensor fails, the service procedure is to replace the complete throttle body assembly and perform a throttle/idle relearn.

What are the signs the TPS/throttle body is playing up?
Look for unstable idle, hesitation, higher fuel use, the check engine light, and limp mode. Codes like P0120–P0124 or P0220–P0223 are common. Always check for intake leaks and wiring issues before fitting a new throttle body.
