Parts for your 2015 Honda Cr-v-Throttle position sensors

2015 Honda CR‑V Throttle Position Sensors (TPS)

Based on Honda’s 2015 CR‑V service information for the K24W “Earth Dreams” engine and common OBD‑II diagnostics for this model (DTCs such as P0121–P0123, P2135), a throttle position sensor set is absolutely used. The vehicle runs Electronic Throttle Control (drive‑by‑wire), with dual throttle position sensors (Sensor A/B) built into the throttle body assembly, plus dual accelerator pedal position sensors. Honda technical literature notes the TPS is integral to the throttle body and typically not serviced separately.

On the 2015 CR‑V, the throttle position sensors tell the engine computer exactly how far the throttle plate is open. That info gets blended with inputs from the pedal sensor, airflow and oxygen sensors to manage fuel, spark and idle. In everyday terms, the TPS helps the CR‑V feel smooth off the line, keeps idle steady with the air con on, and makes throttle response feel natural whether cruising the motorway or inching through traffic.

Because the TPS is part of the electronic throttle body, any issues are treated as throttle body faults rather than a simple bolt‑on sensor swap. When the sensors drift out of spec or their signals disagree, the car can go into limp mode, throw the check engine light, or feel hesitant on acceleration. Codes like P0121, P0122, P0123 or P2135 are common flags.

As part of regular servicing, a shop will usually:

• Scan for stored or pending TPS‑related fault codes and view live data for TP Sensor A/B agreement.
• Visually inspect the throttle body for contamination and check the harness/connector for corrosion or damaged pins.
• Clean light carbon on the throttle bore using throttle‑body‑safe cleaner, taking care not to force the plate by hand.
• Perform an idle learn/reset after cleaning, battery disconnect, or throttle body replacement so the ECU relearns the correct throttle angles.

If replacement is needed, the fix is usually a complete throttle body assembly. After fitting, an idle learn is required, and it’s good practice to clear codes and verify that TP Sensor A/B tracks evenly on a scan tool. Genuine‑quality parts and proper torque on the mounting bolts help prevent vacuum leaks and repeat faults. With clean connectors, a healthy battery/charging system, and the odd throttle clean when drivability gets a bit doughy, the CR‑V’s TPS setup generally soldiers on for many kilometres without drama.

FAQs

Does the 2015 CR‑V actually have a throttle position sensor?
Yes. It uses dual throttle position sensors inside the electronic throttle body, and dual sensors on the accelerator pedal. Honda treats the TPS as part of the throttle body assembly rather than a standalone part.

What are common symptoms of a dodgy TPS on a 2015 CR‑V?
Drivers may notice a check engine light, sluggish or jumpy throttle response, unstable idle, or the car dropping into limp mode. Scan tools often show codes like P0121–P0123 or P2135 when the two TPS signals don’t agree.

Can the TPS be replaced on its own, or is it the whole throttle body?
On this model, the TPS is integrated into the throttle body and isn’t normally serviced separately. Replacement is typically the complete throttle body assembly, followed by an idle learn procedure and verification with a scan tool.
