Parts for your 2009 Nissan Tiida-Throttle position sensors

2009 Nissan Tiida throttle position sensor (TPS): what it does and how to look after it

Yes, the 2009 Nissan Tiida does use a throttle position sensor. On the C11 Tiida (HR16DE/MR18DE engines) the TPS is built into the electronic throttle body and isn’t a separate, adjustable part. This is documented in Nissan’s C11 Factory Service Manual (EC section) and reflected in trade data used by workshops, where throttle angle is read via dual tracks and the unit is replaced as an assembly. Common ECM diagnostics like P0120–P0124, P0222/P0223 and P2135 also reference this sensor arrangement.

The TPS tells the engine computer exactly how far the throttle plate is open, so it can match fuel, spark and idle control to what the driver’s asking for. It works alongside the accelerator pedal position sensor (on the pedal) to deliver smooth take-off, stable idle, cruise control accuracy and decent fuel economy. Because it’s drive-by-wire, the ECM constantly cross-checks both sensors for safety and will drop into limp mode if it sees a mismatch.

While the TPS isn’t a scheduled replacement item, it benefits from sensible servicing. The big one is keeping the throttle body clean. Carbon build-up around the blade can make the sensor’s readings look erratic and cause hunting idle or stalling under the bonnet at the lights. Use a proper throttle-body cleaner, ignition off, and don’t force the blade open by hand. Avoid soaking the actuator area.

If the throttle body is removed or replaced, fit a new gasket, check the wiring plug for corrosion, and torque clamps evenly to prevent air leaks. After any cleaning, battery disconnect, or throttle-body replacement, carry out the throttle closed-position and idle air volume learn. A proper scan tool (CONSULT or equivalent) is the tidy way, the pedal dance method can work but is fussy on timing.

Watch for signs that point to TPS/throttle-body trouble:

• Check Engine Light with codes like P0121, P0122, P0123, P0222, P2135
• Rough or high idle, stalling, or sudden limp mode
• Flat spots on take-off or jumpy throttle response

If faults persist after cleaning and relearn, replacement of the throttle body assembly is the go. It’s not an adjustable sensor on this Tiida, so there’s no mechanical tweak—just correct installation and the relearn procedure. Most workshops will knock this over in about an hour plus the ECM relearn.

• Does a 2009 Nissan Tiida have a separate TPS?
  It’s fitted, but not separate. The TPS is integrated into the electronic throttle body. There’s also an accelerator pedal position sensor at the pedal, which is a different part.
• Can the TPS on a Tiida be adjusted?
  No. There’s no manual adjustment. The ECM handles calibration via throttle closed-position and idle learn routines after cleaning or replacement.
• What does replacement typically cost?
  Because the TPS is part of the throttle body, you’re replacing the whole unit. Expect parts to vary widely—aftermarket through to genuine—plus around an hour of labour and a relearn. Ask your local workshop for an on-the-day quote.

FAQs

Does a 2009 Nissan Tiida have a throttle position sensor?

Yes. The Tiida’s TPS is built into the electronic throttle body assembly. It works with the accelerator pedal position sensor to give the ECM accurate throttle information. If it fails, the whole throttle body is typically replaced.

Can the TPS on a Tiida be calibrated at home?

There’s no screw to adjust. Calibration is done electronically with a throttle closed-position and idle air volume learn. A scan tool makes it straightforward, though the manual pedal procedure can work if timed precisely.

What are the common symptoms of a failing TPS/throttle body?

Check Engine Light, erratic or high idle, stalling, limp mode, and sluggish or jumpy throttle response. Fault codes like P0121, P0122, P0123, P0222 or P2135 are typical clues.
