2022 Honda CR‑V throttle-position-sensors (TPS): usage, purpose and service tips

Based on Honda factory service information for the 2017–2022 CR‑V (Electronic Throttle Control section), the 2022 model does use throttle-position sensors. The throttle body houses dual TP sensors (often labelled TP Sensor A and TP Sensor B) that report throttle plate angle to the powertrain control module. This is backed by Honda’s OBD‑II diagnostics, which include TP‑related DTCs such as P0121, P0122, P0123, P0221, P0222, P0223 and P2135 for this platform, and live data items “TP Sensor A/B” visible on Honda’s HDS scan tool. Most professional parts catalogues list the TPS as integral to the electronic throttle body on this model rather than a separate replaceable sensor.

What the TPS does on a 2022 CR‑V is simple but critical. As part of the drive‑by‑wire system, those twin sensors continuously tell the ECU exactly how far the throttle plate is open. That information is used to meter fuel, control ignition timing, manage turbo boost on the 1.5‑litre petrol, coordinate transmission shift behaviour, and keep cruise control, stability and traction systems happy. Using two sensors provides redundancy and cross‑checks for accuracy—if their signals don’t agree, the ECU throws a fault and may drop the car into a reduced‑power “limp” mode to protect the driveline.

For servicing, the TPS on a 2022 CR‑V isn’t a scheduled replacement item, but it does benefit from good housekeeping around the throttle body. If the car shows a rough idle, hesitant take‑off, surging, poor fuel economy, or a glowing MIL with the TP‑related codes above, it’s time for a proper check. A tech will usually:

• Inspect the throttle body and ducting for oil vapour build‑up and clean the bore and plate with throttle‑safe cleaner.
• Scan live data for smooth, linear TP Sensor A/B tracking from closed to wide‑open throttle, and check the A/B correlation.
• Verify connector condition and harness routing—any green corrosion or pin tension issues can mimic a failed sensor.

If a sensor fails or the correlation is out, Honda supplies the TPS as part of the electronic throttle body assembly on this generation, so replacement is typically the whole unit with a new gasket. After refit (and often after a battery change), an idle/throttle position learn should be carried out with a capable scan tool to stabilise idle and tip‑in. Use quality parts, follow factory torque specs and procedures, and avoid spraying solvents directly into the sensor housing. For most Aussie and Kiwi conditions, a throttle body inspection/clean every 50,000–60,000 km as part of a major service helps keep the TPS readings crisp and the drive silky.

Popular questions

How can someone tell the TPS is playing up on a 2022 CR‑V?
They’ll usually notice a check‑engine light, uneven idle, flat spots on acceleration, or the car going into reduced power mode. A scan will show TP‑related fault codes or jumpy TP Sensor A/B readings. Cleaning the throttle body and checking wiring comes first, if A/B signals still disagree, the throttle body assembly may need replacing.

Can the TPS be replaced on its own, or is it part of the throttle body?
On the 2022 CR‑V, the TPS is integrated into the electronic throttle body and isn’t serviced separately. If the sensor is faulty, the practical repair is to replace the complete throttle body, then perform an idle/throttle learn so the ECU recalibrates to the new unit.

Is a relearn needed after battery replacement or throttle body work?
Yes, it’s good practice. After battery disconnection or throttle body cleaning/replacement, doing an idle/throttle position learn with a suitable scan tool helps stabilise idle speed and ensures accurate TPS tracking. Skipping this can leave the engine idling high or hunting until it adapts.
