Parts for your 2007 Nissan Tiida-Throttle position sensors

2007 Nissan Tiida Throttle Position Sensor (TPS)

Per Nissan’s Tiida C11 Factory Service Manual (Engine Control section), the 2007 Tiida uses Electronic Throttle Control. That means the throttle position sensor is absolutely fitted and relevant on this model. It’s built into the throttle body alongside the throttle control motor, using dual sensor tracks for redundancy. On these HR15DE/HR16DE/MR18DE engines, the TPS isn’t a separate bolt-on part, if the sensor fails, the throttle body assembly is typically replaced. Nissan’s service procedures (CONSULT-based) also call for throttle and idle learning after any work on the assembly.

What does the TPS do? It constantly reports the exact angle of the throttle plate to the engine computer, so fuelling, ignition timing and gearbox behaviour stay on song. With drive-by-wire, the ECU cross-checks the accelerator pedal position against the TPS to deliver smooth response, stable idle and decent economy. If the readings don’t stack up, the car can drop into fail-safe, limit power, or light the check engine lamp.

There’s no scheduled replacement for the TPS on a 2007 Tiida, but good servicing includes keeping the throttle body clean and checking for fault codes. If the sensor goes out of range or tracks disagree, you’ll usually see a CEL and codes like P0121–P0123 or P0221–P0223. Because the TPS is integrated, the practical fix is a quality throttle body assembly with a new gasket. Don’t force the throttle plate by hand, use proper throttle body cleaner and a soft cloth with the battery disconnected.

• Common symptoms: erratic idle, flat spots, poor acceleration, high idle, stalling, limp mode, increased fuel use, and a check engine light.
• Helpful maintenance: clean the throttle body every 40–60,000 kilometres, inspect the harness/connector for corrosion or broken wiring, and confirm ECU grounds are sound.

After replacement or cleaning, follow Nissan’s learning procedures (FSM EC: Electronic Throttle Control):

• Throttle Valve Closed Position Learning
• Accelerator Pedal Released Position Learning
• Idle Air Volume Learning (ideally with a scan tool/CONSULT)

A workshop can complete diagnosis, fitment and relearns quickly, and it’s worth it to avoid rough idle or hunting. If DIY, budget for a new gasket, throttle body cleaner and time for the relearn sequence. Genuine or high-quality aftermarket throttle bodies tend to give the best long-term results.

Popular questions about 2007 Nissan Tiida throttle position sensors

Does a 2007 Nissan Tiida have a separate throttle position sensor I can replace?
No. On the 2007 Tiida (C11), the TPS is integrated into the electronic throttle body with the throttle control motor. If the sensor fails, the recommended repair is to replace the complete throttle body assembly and perform the learning procedures.

What are the signs my Tiida’s TPS is on the way out?
Expect unstable idle, hesitation off the mark, flat spots, higher than normal idle, stalling, a check engine light, and sometimes limp-home mode. Diagnostic trouble codes commonly include P0121–P0123 and P0221–P0223. A technician will also check wiring and grounds before condemning the throttle body.

Do I need to do any resets after throttle body/TPS work?
Yes. Nissan specifies Throttle Valve Closed Position Learning, Accelerator Pedal Released Position Learning, and Idle Air Volume Learning. These can be done with a scan tool (CONSULT) or via the manual pedal/ignition sequence outlined in the factory manual. Skipping them can leave the idle unstable.
