Parts for your 2013 Honda Elysion-Throttle position sensors

2013 Honda Elysion throttle-position-sensor: purpose, fitment and service tips

Yes — the 2013 Honda Elysion uses a throttle-position sensor (TPS). It’s built into the electronic throttle body as part of Honda’s drive-by-wire system. Technical sources that back this up include Honda’s workshop manuals for the Elysion RR-series (RR1–RR4) which illustrate the electronic throttle body with dual TPS circuits (often labelled TP Sensor A/B) and a throttle actuator motor, and Honda’s Electronic Parts Catalogue entries for the Elysion that list the throttle body as an assembly with the sensors integrated rather than supplied separately. Honda service information for the K24A and J-series engines used in this model range (as seen in contemporary Accord/CR‑V manuals) shows the same DBW layout with dual TPS feedback to the PCM.

On the Elysion, the TPS tells the engine computer exactly how far the throttle plate is open. That info is used to meter fuel, manage ignition timing, coordinate automatic transmission shift strategy, run cruise control and traction control, and keep idle smooth. Because it’s a safety‑critical feedback device, Honda uses two TPS tracks inside the throttle body so the PCM can constantly cross‑check them.

Typical signs the TPS/throttle body is playing up include an erratic idle, sudden loss of power, “limp” mode, poor kickdown, delayed shifts, or a glowing check‑engine light with codes like P0121/P0122/P0123 or P2135. On this model, the TPS is not a separate bolt-on piece — if the sensor fails, the fix is usually a replacement throttle body assembly.

As part of routine servicing on a 2013 Honda Elysion, it’s smart to:

• Inspect the intake ducting for splits or loose clamps that can skew TPS/airflow readings.
• Clean the throttle bore and plate with a throttle-body safe cleaner (no harsh solvents, don’t flood the motor housing, and don’t force the plate by hand).
• Check electrical connectors for corrosion, moisture ingress or damaged pins, ensure solid grounds.
• If the throttle body is replaced, fit a new gasket, follow the workshop manual torque specs, and perform the idle learn/throttle relearn with a scan tool or the Honda key-on procedure so the PCM re‑adapts.

Quality parts and correct setup go a long way. A healthy TPS signal helps the Elysion feel crisp off the line, shift cleanly, and run efficiently on Aussie and Kiwi roads.

Popular questions about 2013 Honda Elysion throttle-position-sensors

Where is the TPS on a 2013 Honda Elysion?
The TPS is inside the electronic throttle body on the intake manifold. It’s not a separate sensor on the shaft, Honda integrates two TPS tracks and the actuator motor into the throttle body housing. Access is from the engine bay by removing the intake duct.

Does it need calibration after replacement?
Yes. After replacing or disconnecting the throttle body, perform the throttle/idle learn so the PCM relearns the fully closed and fully open positions. This can be done with a compatible scan tool or by following the Honda idle learn procedure detailed in the service manual.

What are the common failure symptoms?
Drivers often notice unstable idle, hesitation or surging on light throttle, poor fuel economy, and a check‑engine light with codes like P0121–P0123 or P2135. If wiring checks out, the usual cure is a new throttle body assembly because the TPS isn’t serviced separately.
