Parts for your 2006 Honda Odyssey-Throttle position sensors

2006 Honda Odyssey throttle-position-sensors: what they do and how to look after them

Yes, the 2006 Honda Odyssey is fitted with throttle-position-sensors (TPS). Honda’s own Factory Service Manual for the 2005–2010 Odyssey (Electronic Throttle Control System section) and OEM wiring diagrams confirm the J35 V6 uses drive‑by‑wire with two throttle position tracks (often labelled TP Sensor A and TP Sensor B) built into the electronic throttle body. Technical databases such as ALLDATA and Mitchell1 also note the TPS is integral to the throttle body and not serviced separately.

On this model, the TPS tells the engine computer exactly how far the throttle plate is open. That data is paired with the accelerator pedal position sensor under the dash, letting the ECU command smooth, precise throttle movement without a physical cable. The result is better drivability, emissions control and fuel economy over thousands of kilometres.

Because the TPS is part of the throttle body, replacement typically means swapping the complete throttle body assembly rather than a stand‑alone sensor. It isn’t adjustable, and trying to tweak it will only cause dramas. Common warning signs include erratic idle, hesitation, a “limp” mode feel, higher fuel use, harsh shifting, or a Check Engine Light with codes like P0121–P0123, P0221–P0223 or P2135 (TP correlation).

Good servicing habits help keep the Odyssey happy under the bonnet:

1. Scan first. Confirm any TPS‑related fault codes and view live data for TP Sensor A/B agreement.
2. Check the basics. Inspect the throttle body connector and loom for corrosion, moisture or damage.
3. Clean correctly. If the throttle plate is gummed up, remove the intake duct and gently clean with throttle‑safe cleaner. Don’t force the plate by hand.
4. Replace when required. If the sensors fail or correlation persists, fit a new genuine or high‑quality throttle body. Use a new gasket and torque fasteners to factory spec.
5. Perform an idle learn. After cleaning or replacement, carry out the Honda idle/ETCS relearn with a scan tool, or follow the manual procedure (battery/ECU reset, then idle with all loads off until warm and stable). Avoid A/C, steering input and electrical loads during the relearn.

Looked after properly, the throttle body and its twin TPS tracks deliver years of reliable service, keeping the family hauler smooth and responsive on Aussie and Kiwi roads.

Popular questions about 2006 Honda Odyssey throttle-position-sensors

Can the TPS be replaced separately on a 2006 Odyssey?
No. On this model the TPS is integrated into the electronic throttle body as dual sensors. If testing confirms a TPS fault, the proper fix is to replace the complete throttle body assembly and then perform an idle/ETCS relearn.

What are the common symptoms of a failing TPS on this vehicle?
Drivers may notice erratic idle, stumbling on take‑off, sudden loss of power or “limp” mode, harsh gear changes, poorer fuel economy and a Check Engine Light. Diagnostic trouble codes often include P0121–P0123 or P2135 indicating throttle position performance or correlation issues.

Do I need a relearn after cleaning or replacing the throttle body?
Yes. A throttle/idle learn is required so the ECU can relearn the throttle plate position. Use a capable scan tool to run the ETCS reset, or follow the factory procedure: reset the ECU, start the engine with all accessories off, and allow it to idle undisturbed until warm and stable.
