Parts for your 2010 Honda Cr-v-Throttle position sensors

2010 Honda CR‑V throttle position sensor (TPS): what it does and how to look after it

Based on Honda’s technical literature for the 2007–2011 CR‑V (Service Manual: Fuel & Emissions and Electronic Throttle Control sections), the model uses electronic throttle control with dual throttle position sensors (Sensor A/B) built into the throttle body. Honda’s OBD‑II DTC list for this vehicle also includes throttle position–related faults (e.g., P0121, P0122, P0221, P0222), and the Honda parts catalogue shows the TPS integrated with the throttle body assembly rather than as a separate, serviceable part. So yes—the 2010 Honda CR‑V does have TPS functionality, and it’s integral to the electronic throttle body.

On a 2010 CR‑V, the throttle position sensors tell the engine control unit exactly how far the throttle plate is open. Working alongside the accelerator pedal position sensor, the dual TPS tracks provide a precise, redundant signal so the ECU can manage air intake, spark timing, and fuel delivery smoothly. That’s why the car feels crisp off the mark and settles into a steady idle—when the TPS is healthy, the ECU always knows what the throttle’s doing.

Because Honda uses a drive‑by‑wire setup on this model, the TPS isn’t a bolt‑on, standalone sensor like older cable‑throttle cars. It’s part of the throttle body assembly with the throttle motor. If the TPS goes out of spec or becomes unreliable, the fix is typically to replace the entire throttle body. After replacement—or if the battery has been disconnected—an idle/throttle relearn with a scan tool (or by following Honda’s manual procedure) is needed so the ECU can recalibrate the throttle angle and idle control.

There’s no scheduled replacement interval for the TPS. Instead, keep an eye out for tell‑tale signs and maintain the throttle body sensibly:

• Symptoms to watch: unstable idle, hesitation, sudden loss of power, limp‑home behaviour, or the MIL on with throttle‑related DTCs (P0121/P0122/P0221/P0222).
• Good habits: avoid forcing the throttle plate by hand, when cleaning the throttle body, use sensor‑safe cleaner, don’t flood the electronics, and let it dry thoroughly.
• After any cleaning or battery reset: perform the Honda idle learn so the ECU re‑adapts to the clean throttle plate position.

If diagnostics point to a TPS fault, a technician will confirm by checking live data for TPS A/B agreement, performing sweep tests for dead spots, and verifying wiring integrity. If the sensor is faulty, replacing the throttle body assembly with a quality unit and completing the relearn generally restores clean, consistent throttle response and reliable cruising—too easy.

FAQs

Does the 2010 Honda CR‑V actually have a throttle position sensor?

It does. The TPS function is built into the electronic throttle body as dual sensors (A/B). It isn’t a separate bolt‑on part like older cable‑throttle setups.

Can the TPS be replaced on its own on a 2010 CR‑V?

No. On this model, the TPS is integrated with the throttle body and isn’t serviced separately. If the TPS fails, the standard repair is replacing the throttle body assembly and then performing a throttle/idle relearn.

What are common signs of a failing TPS on a 2010 CR‑V?

Drivers may notice erratic idle, flat spots on acceleration, sudden power loss or limp‑home behaviour, and the check‑engine light. Scan results often show throttle position–related DTCs (like P0121 or P0222) and disagreeing or jumpy TPS A/B signals.
