Parts for your 2022 Mitsubishi Eclipse cross-Throttle position sensors

2022 Mitsubishi Eclipse Cross Throttle Position Sensor (TPS)

Technical references confirm the 2022 Mitsubishi Eclipse Cross does use a throttle position sensor. The Mitsubishi Motors Workshop Manual for the Eclipse Cross (GK) electronic throttle control system notes an electronic throttle body with a DC motor and dual throttle position sensors, alongside a dual-channel accelerator pedal position sensor. Trade databases such as Autodata and ALLDATA likewise list the MY22 throttle body as an assembly with integrated TPS. So, a TPS is absolutely relevant on this model.

This Eclipse Cross runs a drive-by-wire setup, and the TPS is the eyes of the ECU for what the throttle blade is actually doing. It reports throttle plate angle in real time so the engine computer can juggle air, fuel, spark and idle speed, keep boost under control, and deliver smooth response through the CVT. The unit in the throttle body is typically dual-channel for redundancy, constantly cross-checked against the accelerator pedal sensors—handy for safety and for keeping the throttle feel consistent on Aussie and Kiwi roads.

There’s no scheduled replacement interval for the TPS, it’s more about condition and data. As part of regular servicing, it’s smart to scan for fault codes and look at live data—both pedal and throttle angle should track smoothly and agree. Under the bonnet, check the throttle body connector for moisture or green fuzz, make sure the loom isn’t chafing, and keep the throttle bore clean with proper throttle-body cleaner. Don’t force the blade open by hand, that can upset the motor gears or sensor alignment. If the battery’s been weak, sort that too—low system voltage can throw the throttle system into a tizz.

When the TPS plays up, the car may light the MIL, drop into limp mode, surge at idle, or feel dead off the line. Common codes include P0120–P0123, P2135, P2101 and P2119. On the 1.5T Eclipse Cross, the TPS is integrated, you replace the complete throttle body rather than the sensor alone. Best practice:

• Confirm with a scan tool: check correlation between pedal and throttle angles, and for clean, linear signals.
• Inspect wiring and grounds before condemning the unit.
• Replace the throttle body with a new gasket, torque to spec.
• Perform throttle/idle relearn with a capable scan tool, update ECM software if available.
• Road test for stable idle, crisp response and no new codes.

FAQs

Does the 2022 Eclipse Cross have a TPS or only a pedal sensor?
It’s got both. The accelerator pedal uses dual sensors to tell the ECU what the driver wants, and the electronic throttle body houses dual throttle position sensors to report what the blade is actually doing. The ECU cross-checks the two for accuracy and safety.

What are common TPS fault codes and symptoms on the Eclipse Cross?
Typical codes include P0120–P0123 (TPS circuit range/performance), P2135 (pedal/throttle correlation), and P2101/P2119 (throttle actuator performance). Symptoms can be a check engine light, limp mode, erratic idle, flat throttle response, and increased fuel use.

Can the TPS be cleaned or replaced on its own?
On this model the sensor is integrated into the throttle body, so it’s normally a complete throttle body replacement. Cleaning the throttle bore can help sticky response, but if the sensor tracks poorly or sets correlation faults, replacement and a proper throttle/idle relearn with a scan tool are the go.
