Parts for your 2007 Honda Elysion-Throttle position sensors

2007 Honda Elysion throttle position sensor (TPS) — what it does and how to look after it

Technical documentation for Honda’s mid‑2000s K24A and J30A engines confirms the 2007 Honda Elysion does use throttle position sensing. On this model it’s part of Honda’s electronic throttle control (drive‑by‑wire), which integrates dual throttle position sensors (often labelled TP Sensor A/B) inside the throttle body. Honda’s service manuals for contemporary models using the same powertrains, along with Honda’s technical training on PGM‑FI, note the TPS is not serviced separately, if the sensor fails, the complete throttle body assembly is replaced. Honda’s Electronic Parts Catalogue for Elysion (RR series) also lists the TPS as built into the throttle body.

On a 2007 Elysion, the throttle position sensor’s job is to tell the ECU exactly where the throttle plate sits. Alongside the accelerator pedal sensors, it keeps fuelling, ignition timing, idle speed and even auto‑shift behaviour smooth and responsive. Because it’s a drive‑by‑wire setup, the ECU constantly cross‑checks TPS A/B signals, if they disagree or go erratic, it can drop into limp mode to protect the engine and transmission.

As part of routine servicing, it pays to keep the throttle body clean. Over time, carbon builds up around the plate, causing a sticky feel off‑idle, hunting at idle or sluggish tip‑in. Under the bonnet, remove the intake duct, then carefully clean only the bore and plate with throttle‑body‑safe cleaner and a lint‑free cloth. Don’t drown the external electronics and don’t force the plate open by hand, use the key‑on pedal to open it if needed. After battery disconnection or cleaning, perform an idle learn so the ECU re‑calibrates—let it idle with all accessories off until the cooling fans cycle twice. A scan tool can also run the throttle and idle relearn on many Hondas.

If faults persist—think hesitation, surging, stalling, poor economy, or codes like P0121, P0122, P0123, P0222 or P2135—the fix on this Elysion is replacement of the throttle body assembly rather than the TPS alone. Use a new gasket, torque the mounting bolts to spec (about 22 N·m is typical for Honda throttle bodies), and top up/bleed coolant if your model routes coolant through the body. After fitting, complete the idle learn. Quality OEM or reputable aftermarket throttle bodies tend to give the best results. For Kiwi and Aussie owners, a quick scan of live data is handy—the TP% should sweep smoothly from closed to wide open with no dead spots. Checking and cleaning every 60,000–100,000 kilometres keeps things sweet between bigger services.

FAQ

Does a 2007 Honda Elysion have a throttle position sensor?
Yes. It uses dual throttle position sensors built into the electronic throttle body. They feed the ECU precise throttle‑plate angle so fuelling and idle control stay on point. Unlike older cable‑throttle Hondas, the sensors aren’t a separate bolt‑on piece.

Can the TPS be replaced separately on this model?
No. On the 2007 Elysion, the TPS is integrated with the throttle body and isn’t serviced on its own. If the TPS fails or goes out of calibration, the remedy is to replace the complete throttle body assembly, fit a new gasket and carry out an idle relearn.

What are common signs of a failing TPS/throttle body on an Elysion?
Owners may notice a hesitant launch, surging cruise, unstable idle, worse fuel use, and the MIL on. Scan tools often show codes like P0121–P0123, P0222 or P2135. Before replacement, try a careful throttle‑body clean and then an idle relearn, if data still looks jumpy or the codes return, the throttle body assembly is likely due.
