Parts for your 2023 Honda Cr-v-Throttle position sensors

2023 Honda CR‑V throttle position sensors

Technical sources confirm the 2023 Honda CR‑V is fitted with throttle position sensors (TPS). Honda Service Information for the 2023 CR‑V (PGM‑FI, Electronic Throttle Control System) details dual Throttle Position Sensors A/B integrated into the electronic throttle body, with related DTCs P0121–P0123, P0221–P0223 and P2135 listed in the factory DTC index. Honda’s genuine parts catalogue for the 2023 CR‑V also shows the TPS as part of the throttle body assembly, not typically sold separately. That makes TPS relevant on both petrol and hybrid variants.

On the 2023 CR‑V, the throttle position sensors let the ECU know exactly how far the throttle plate is opened. Working alongside the accelerator pedal position sensors and the throttle actuator motor, they keep the engine smooth, responsive, and efficient. When the sensors agree with each other, the ECU can fine‑tune air, fuel, and ignition for easy take‑offs, tidy overtakes, and tidy fuel economy around town and on long Kiwi and Aussie stretches.

Because Honda integrates the TPS inside the throttle body, it’s not usually a standalone replacement. If a TPS track goes out of range or the pair of sensors disagree, expect a Check Engine light, limp‑home mode, rough idle, or surging under steady throttle. The ECU will often log codes such as P0121/P0122/P0123 (TP Sensor A) or P0221/P0222/P0223 (TP Sensor B), and sometimes P2135 (correlation) — all flagged in Honda’s DTC documentation.

Servicing-wise, the smart play is prevention. During routine servicing, a careful clean of the throttle bore and plate with sensor‑safe throttle cleaner can help maintain stable idle and sensor readings. Avoid soaking the shaft area and never force the plate — the drive‑by‑wire gears and position tracks are delicate. If faults persist after cleaning and wiring checks, replacement of the throttle body assembly with a genuine unit is the reliable fix.

After any throttle body work or battery disconnect, an idle/throttle learn is required. Honda’s service procedures outline an ETC/idle learn using a scan tool or a prescribed idle sequence so the ECU relearns the plate positions. Skipping this step can leave the CR‑V idling high, stalling at stops, or feeling a bit doughy off the mark. With the right parts and procedures, the 2023 CR‑V’s TPS setup delivers years of drama‑free motoring across Aussie highways and New Zealand backroads.

• Signs of TPS trouble: warning light, limp mode, irregular idle, flat spots, poor economy.
• Best practice: inspect connectors and wiring, clean throttle body, follow Honda relearn steps.
• Replacement: throttle body assembly (TPS integrated), use genuine components for correct calibration.

FAQs

Where is the throttle position sensor on a 2023 Honda CR‑V?
The TPS is built into the electronic throttle body on the intake manifold. Honda supplies it as part of the throttle body assembly rather than as a separate bolt‑on sensor.

Does the 2023 CR‑V need a relearn after throttle body or battery work?
Yes. Honda specifies an ETC/idle learn after throttle body replacement, cleaning that alters plate position, or battery disconnect. Without it, idle quality and throttle response can be off until the ECU relearns the stops.

What fault codes point to TPS issues on the 2023 CR‑V?
Common TPS‑related codes include P0121–P0123 (TP Sensor A), P0221–P0223 (TP Sensor B), and P2135 (A/B correlation). These are documented in Honda’s factory DTC list for the 2023 model.
