Parts for your 2012 Nissan Tiida-Throttle position sensors

2012 Nissan Tiida Throttle Position Sensor (TPS)

Based on the Nissan C11 Tiida/Versa Factory Service Manual (EC section, Electronic Throttle Control) for model years around 2011–2012, and common diagnostic data (DTCs P0120–P0123, P2135) listed in Nissan technical literature and Autodata, the 2012 Nissan Tiida is equipped with an electronic throttle control (drive-by-wire) throttle body that contains dual throttle position sensors. So yes, a TPS is fitted and relevant on this model—it's integrated into the throttle body assembly rather than being a separate bolt-on sensor.

On a 2012 Tiida, the TPS’s job is to tell the engine computer exactly how far the throttle plate is open. That info helps the ECU manage fuel, ignition timing, idle speed, cruise control and even gearbox behaviour. Because it’s a drive-by-wire setup, the throttle body combines a DC motor with two throttle angle sensors for redundancy. If the readings disagree, the ECU can put the car into limp mode to protect the engine and occupants.

Servicing-wise, the TPS isn’t a standalone part you can replace by itself—it’s built into the throttle body. If the sensor fails, the fix is typically a complete throttle body replacement. Use a new gasket, don’t overtighten the bolts, and avoid forcing the butterfly by hand. Cheap pattern parts can cause flaky signals, many workshops prefer genuine or reputable-brand units.

Plenty of Tiidas benefit from periodic throttle body cleaning, especially if there’s oil vapour from the PCV system. Every 20,000–30,000 km, a careful clean with throttle-safe cleaner can smooth out a hunting idle or hesitant tip-in. Keep solvents out of the electronics, and don’t soak the unit.

Very important for this Nissan: after cleaning or replacing the throttle body, carry out Throttle Valve Closed Position Learning and Idle Air Volume Learning. Skipping these can leave the idle too high or unstable. A decent scan tool makes it straightforward, there’s also a manual procedure in the FSM if needed. Under the bonnet, look out for symptoms like erratic idle, flat spots on acceleration, higher fuel use, or the MIL on with codes like P0120–P0123 or P2135. If those pop up, get the signals graphed on a scan tool before ordering parts.

• Common signs: stalling or surging, sluggish response, limp mode, poor economy.
• Good practice: clean the throttle body periodically, relearn settings, and use quality parts.

FAQs

Does the 2012 Nissan Tiida have a separate TPS or is it built into the throttle body?
It’s built in. The Tiida’s electronic throttle body houses dual throttle position sensors and a motor. If the sensor plays up, the usual remedy is replacing the entire throttle body rather than a standalone sensor.

Do I need to recalibrate the throttle after cleaning or replacing it?
Yes. Perform Throttle Valve Closed Position Learning and Idle Air Volume Learning. Without this, the idle can be unstable or too high. A capable scan tool is the easiest way, though the factory manual outlines a pedal/ignition sequence that also works.

What fault codes or symptoms point to a TPS issue on a Tiida?
Look for P0120–P0123 or P2135, along with rough idle, hesitation, and limp mode. If these appear, verify wiring and connector condition, then test the throttle body signals before committing to replacement.
