2013 Honda CR‑V throttle position sensors: what they do and how to look after them

Based on Honda’s 2012–2014 CR‑V Service Manual (PGM‑FI, Electronic Throttle Control System) and Honda parts catalogues for the RM‑series CR‑V, the 2013 Honda CR‑V uses an electronic throttle body with built‑in throttle position sensors (TP Sensor A and B). These sensors are integral to the throttle body and not serviced separately. Diagnostic references for this model also list DTCs such as P0121–P0123 and P2135 for TP sensor range/correlation, confirming that throttle position sensing is present and relevant on this vehicle.

On a 2013 CR‑V, the throttle position sensors constantly report the exact angle of the throttle plate to the engine computer. Paired with the accelerator pedal position sensor, they’re the brains behind the drive‑by‑wire setup—delivering smooth throttle response, stable idle, decent fuel economy, and proper operation of cruise control and stability systems. Because Honda packages TP Sensor A/B inside the electronic throttle body, it’s a precise, redundant arrangement designed to keep the car safe if one channel goes out of whack.

There’s no scheduled replacement interval for the throttle position sensors, they’re a “replace on fault” component. Common clues they’re unhappy include erratic idle, hesitation, limp mode, or the check engine light with codes like P0121, P0122, P0123, or P2135. Before throwing parts at it, it’s worth checking the throttle body connector for corrosion, verifying battery and charging health, and ruling out intake leaks.

If the sensor fails, the fix on this model is typically a complete throttle body replacement rather than swapping a stand‑alone TPS. That means removing the intake ducting, unplugging the throttle body, and dealing with the coolant hoses that warm the housing—be ready to catch and top up coolant. Always fit a new gasket, torque the fasteners evenly, and never force the throttle plate by hand. After cleaning or replacement, perform an idle/throttle relearn: clear ECM adaptations with a scan tool (or disconnect the battery if appropriate), start the engine from cold, let it idle with all accessories off until the radiator fan cycles, then allow a few more minutes of idle. A short, gentle drive cycle helps the ECU fine‑tune.

Good practice between services is simple: keep the intake air filter fresh, avoid spraying harsh cleaners past the mass airflow area, and if cleaning the throttle bore, use sensor‑safe throttle cleaner sparingly. Done right, the CR‑V’s throttle position sensors will deliver reliable kilometres across Aussie and Kiwi roads.

• Typical TPS‑related DTCs on this model: P0121, P0122, P0123, P2135
• Component is integrated, replacement is the throttle body assembly
• Idle/throttle relearn is essential after cleaning or replacement

Popular questions

Does the 2013 Honda CR‑V have a separate TPS I can replace?
Not on this model. Honda integrated Throttle Position Sensor A and B inside the electronic throttle body. If the sensor circuitry fails or readings don’t correlate, the usual remedy is to replace the entire throttle body assembly and carry out an idle/throttle relearn.

What’s the idle relearn after throttle body work?
Clear learned values with a scan tool if available. Start the engine cold, all accessories off, and let it idle until the radiator fan runs. Keep idling for a few more minutes, then take a short, gentle drive. This helps the ECU settle the new baseline so throttle response and idle are smooth.

Which fault codes point to TPS issues on a 2013 CR‑V?
Look for P0121 (TPS range/performance), P0122 (TPS low), P0123 (TPS high), and P2135 (TPS A/B correlation). These indicate the ECU isn’t happy with throttle plate feedback and may trigger reduced‑power mode to protect the engine and driveline.
