2007 Honda Odyssey throttle position sensor: what it does and how to look after it

Yes, the 2007 Honda Odyssey uses a throttle position sensor (TPS). Honda’s own 2007 Odyssey Service Manual (PGM‑FI, Electronic Throttle Control System) specifies an electronic throttle body that contains an actuator motor and two internal throttle position sensors (TP Sensor A and TP Sensor B). These sensors aren’t serviced separately, if a TPS fault is confirmed, Honda directs replacement of the complete throttle body assembly. Independent service databases like Mitchell 1 and ALLDATA echo the same guidance and list related DTCs such as P0121, P0122, P0123, and P2135.

On this model, the TPS tells the engine computer exactly how far the throttle plate is open, so fuelling and ignition can be dialled in smoothly. Because the Odyssey runs drive‑by‑wire, there’s no cable from the pedal to the throttle. Instead, the pedal has its own accelerator position sensor, while the throttle body houses the twin TPS sensors to cross‑check position and keep things safe and responsive.

If the Odyssey’s TPS goes out of whack, drivers may notice a rough or hunting idle, flat spots on take‑off, cruise control dropouts, sudden limp‑home behaviour, or the MIL lighting up. The ECM will usually log a code and may compare Sensor A and B for correlation to catch intermittent faults.

• Servicing tips: if there are no TPS‑specific faults, keep the throttle body clean. Use throttle‑body‑safe cleaner, don’t soak the electronics, and don’t force the plate open under the bonnet.
• If replacement is needed: order a complete throttle body (new gasket recommended). The TPS isn’t adjustable, it comes calibrated in the assembly.
• After any throttle body work: perform the Honda idle learn procedure so the ECM relearns airflow at idle. Clear codes with a scan tool and verify warm idle and throttle response.

Home tinkerers can check basics first: battery health, clean air filter, and secure connectors at the throttle body and pedal. If a TPS‑related DTC returns, professional diagnosis is smart—technicians will confirm power/ground, signal integrity for both TP sensors, and rule out wiring faults before condemning the assembly. Using genuine‑spec parts and following the idle learn helps avoid annoying surges and keeps the Odyssey running sweet across Aussie and Kiwi kilometres.

Popular questions

Does a 2007 Honda Odyssey have a throttle position sensor?
It does. The TPS is built into the electronic throttle body along with the actuator motor, and there are two TPS circuits (A and B) for redundancy. It isn’t a separate bolt‑on sensor on this model.

What are common signs of a failing TPS on a 2007 Odyssey?
Expect an illuminated check‑engine light, erratic idle, hesitation on acceleration, or limp‑mode behaviour. Scan tools often show codes like P0121–P0123 or P2135 if the ECM sees out‑of‑range or mismatched TPS signals.

Can the TPS be cleaned or adjusted on this Odyssey?
No adjustment is provided. The TPS is sealed inside the throttle body. You can clean the throttle bore and plate carefully, but if the TPS itself is faulty, replace the throttle body assembly and carry out the idle learn procedure.
