Parts for your 2007 Honda Accord-Throttle position sensors

2007 Honda Accord throttle position sensors

Based on Honda factory service information for the 2003–2007 Accord range (PGM‑FI/ETCS chapters), Honda technical training on Electronic Throttle Control, and OEM parts catalogues used by dealerships and independent workshops, the 2007 Honda Accord is fitted with throttle position sensors. Drive‑by‑wire models use dual TP sensors (Sensor A and B) integrated into the electronic throttle body, while some cable‑throttle variants in certain markets use a separate, replaceable TPS mounted on the throttle shaft. Diagnostic manuals for this model list TP‑related DTCs (such as P0121–P0123, P0221–P0223), further confirming their presence and function.

On a 2007 Accord, the throttle position sensors tell the engine computer exactly how far and how quickly the throttle plate is opening. That info is used to fine‑tune fuel delivery, ignition timing and, on drive‑by‑wire cars, to command the throttle motor itself. It also feeds into cruise control, A/C load compensation, traction/VSA, and auto transmission shift logic. In short, the TP sensors help keep the car smooth, responsive and economical.

They’re not a routine “replace at X km” item, but they do benefit from some attention during servicing. When the throttle body is cleaned, the technician should check the TPS connector for corrosion, damaged pins or a loose fit, and confirm the harness isn’t under tension. On DBW cars, the TP sensors are part of the throttle body assembly and not serviced separately, if a sensor fails tests, the usual fix is a replacement throttle body followed by an idle/throttle learn. On cable‑throttle variants, a standalone TPS can be replaced and set to spec with a scan tool or following the alignment procedure in service data.

Common clues of a TP sensor issue include a check engine light with codes like P0121/P0122/P0123 or P0221/P0222/P0223, erratic idle, flat spots on take‑off, poor fuel economy, unexpected “limp” behaviour, or odd shift timing on autos. Because these symptoms can overlap with vacuum leaks or throttle body grime, a proper diagnosis (voltage sweep test and live‑data checks) is the smart move before ordering parts.

Handy tips for owners and techs:

• Don’t pry open a DBW throttle body, the sensor module is sealed.
• After battery disconnection, throttle body replacement or TPS work, perform an idle/throttle relearn. A capable scan tool makes it easy, but Honda’s no‑load warm‑up and idle learn procedure also does the trick.
• If replacing the throttle body, use a new gasket, torque evenly, and verify there are no intake leaks before relearn.

With quality parts and correct setup, the Accord’s TP sensors are generally set‑and‑forget, keeping the daily drive drama‑free.

Popular questions about 2007 Honda Accord throttle position sensors

Does a 2007 Accord actually have a throttle position sensor?
Yes. Technical manuals for the 2007 Accord specify throttle position sensing on all engines. Drive‑by‑wire versions house dual sensors inside the electronic throttle body, while some cable‑throttle variants use a separate TPS on the throttle shaft. The ECU monitors these signals for precise control and safety redundancy.

What are the signs the TPS is on the way out?
Typical signs include a check engine light with TP codes (P0121–P0123/P0221–P0223), hesitation, surging, rough or hunting idle, higher fuel use, and on autos, unusual shift timing. Because other faults can mimic these, a scan of live data and a sensor sweep test are recommended before replacement.

Can the TPS be reset without a scan tool?
A scan tool is ideal, but many workshops successfully perform Honda’s idle/throttle learn after battery reset or throttle body work without one. This involves warming the engine fully with no electrical loads, then letting it idle undisturbed so the ECU relearns target positions. A capable scanner speeds the job and confirms the result.
