Parts for your 2006 Honda Cr-v-Throttle position sensors

2006 Honda CR‑V throttle position sensor (TPS)

Yes, the 2006 Honda CR‑V is fitted with a throttle position sensor. Factory technical sources confirm this: the Honda CR‑V 2002–2006 Service Manual (PGM‑FI section) details diagnostics for the Throttle Position (TP) Sensor including DTCs P0121, P0122 and P0123, and the Honda electronic parts catalogue shows the TP sensor mounted on the throttle body of the K24A cable‑operated throttle. Industry repair information platforms (e.g., Alldata/Mitchell1) also list TP sensor testing and replacement procedures for this model.

On a 2006 CR‑V, the TPS sits on the side of the throttle body and tells the engine control module exactly how far the throttle plate is open. That signal helps the ECU manage fuelling, ignition timing, idle control and even the way the auto shifts under load. When it’s healthy, throttle response feels clean and predictable, when it’s crook, you’ll often feel flat spots, hunting idle or a stubborn check engine light.

Honda’s service literature treats the TPS as part of the throttle body assembly on this model, so genuine parts are typically supplied with the body rather than as a separate sensor. Aftermarket stand‑alone sensors do exist, but fitting them usually involves removing the factory shear screws, installing the new unit and calibrating the closed‑throttle voltage.

• Common symptoms of a dodgy TPS: hesitation on take‑off, erratic idle, surging, harsh or odd shifts (auto), poor fuel economy and codes P0121/P0122/P0123.
• Basic checks: inspect the 3‑pin connector for corrosion, ensure a solid 5 V reference and ground, and verify smooth signal sweep with a scan tool.

Servicing tips for Aussie and Kiwi owners: if you’re cleaning the throttle body, avoid soaking the TPS in solvent—keep sprays away from the sensor and its seal. If replacement is needed and you fit a complete throttle body, it’s largely bolt‑off, bolt‑on with a fresh gasket. If installing an aftermarket TPS, take the time to set the closed‑throttle signal to roughly 0.5 V (about 0.45–0.55 V is common Honda spec) and check for around 4.5 V at wide open. After any work, carry out the idle learn: warm the engine, then let it idle with all loads off for a few minutes so the ECU can settle. A short road test across a range of speeds and a few kilometres will confirm the lot’s behaving as it should.

Popular questions

Does the 2006 CR‑V actually have a TPS or is it drive‑by‑wire?
It has a cable‑operated throttle with a TP sensor on the throttle body. Drive‑by‑wire arrived on later Hondas. The service manual for the 2002–2006 CR‑V outlines TPS diagnostics and codes, which is the giveaway that the sensor is present and monitored by the ECU.

Can the TPS be replaced on its own, or do I need a new throttle body?
Factory guidance generally replaces the throttle body as an assembly. However, quality aftermarket TPS units are available. If going that route, expect to remove the factory shear screws, fit the new sensor and perform a careful voltage calibration before an idle learn.

What OBD‑II codes point to a TPS issue on a 2006 CR‑V?
The usual suspects are P0121 (range/performance), P0122 (low input) and P0123 (high input). If one of these is logged, confirm wiring integrity, 5 V reference and ground before condemning the sensor. A scan tool graph should show a smooth, linear throttle angle signal from closed to wide open.
