Parts for your 2016 Honda Cr-v-Throttle position sensors

2016 Honda CR‑V throttle-position-sensors — what they do and how to look after them

Based on Honda’s service information (Electronic Throttle Control System section of the CR‑V Service Manual) and factory OBD‑II diagnostics for the 2016 model year (which list DTCs such as P0121–P0123, P0222–P0223 and P2135 for throttle position faults), the 2016 Honda CR‑V absolutely uses throttle-position-sensors. They’re built into the electronic throttle body as dual, non‑adjustable sensors (often called TP Sensor A and B) and work alongside the accelerator pedal position sensor.

On this CR‑V, the throttle-position-sensors report the precise angle of the throttle plate to the engine computer. That signal is critical for fuelling, ignition timing, idle speed control, emissions, and smooth take‑off and shift behaviour. With drive‑by‑wire, the ECU compares the accelerator pedal request to the throttle body’s position via the two TPS channels to keep everything safe and responsive. If they don’t agree, it’ll flag a code and may limit power to protect the drivetrain.

There’s no routine replacement interval for throttle-position-sensors on a 2016 Honda CR‑V. They’re designed to last the life of the throttle body, and on this model they’re not serviced or adjusted separately. Practical care is simple: keep the throttle body clean and the connectors dry and tight. In dusty or stop‑start city use, a gentle throttle body clean every 40–60,000 kilometres helps prevent sticky plates and erratic idle. Use a throttle‑body‑safe cleaner, avoid flooding the electronics, and don’t force the plate by hand.

Common clues that the TPS circuit isn’t happy include a check engine light, hunting or high idle, flat spots on acceleration, cruise control dropping out, or the vehicle going into a reduced‑power “limp” mode. Codes like P0121/P0122/P0123 or P2135 are the usual suspects. Always rule out intake air leaks, carbon build‑up and connector issues before condemning the throttle-position-sensors.

If diagnostics point squarely at the TPS, the fix on a 2016 CR‑V is typically a complete throttle body replacement (new gasket recommended). After fitting, perform the idle/throttle learn procedure with a compatible scan tool or follow Honda’s battery‑reset and warm‑idle process so the ECU can relearn the new position values. Use quality parts, torque fasteners to spec per Honda data, and check for any applicable ECU updates. Done right, the CR‑V will idle smoothly, pull cleanly and keep fuel economy on song.

• Best practice: inspect the wiring connector, clean the throttle body sensibly, and run a proper scan with live data before replacing parts.
• Relevant DTCs: P0121–P0123, P0222–P0223, P2135 (throttle-position-sensor correlation).

FAQs

Does a 2016 Honda CR‑V have a throttle-position-sensor?
Yes. The 2016 CR‑V uses an electronic throttle body with dual throttle-position-sensors (TP Sensor A and B). They’re integral to the throttle body and are monitored by the ECU for accuracy and redundancy.

Can the TPS be replaced separately on a 2016 CR‑V?
No. On this model the TPS is not a standalone service part. If testing confirms a TPS fault, the usual repair is to replace the complete throttle body assembly, then carry out the idle/throttle learn.

What are the signs of a failing TPS on a 2016 CR‑V?
Typical signs include a check engine light, irregular idle, hesitation on tip‑in, poor fuel economy, or reduced‑power mode. Scan tools often show codes such as P0121–P0123, P0222–P0223, or P2135 when the TPS signals are out of range or don’t agree with each other.
