2022 Honda Civic throttle position sensors (TPS): what they do and how to look after them

Based on Honda’s factory service information for the 2022 Civic (Electronic Throttle Control System section) and standard OBD‑II documentation used by Honda diagnostic tooling, the 2022 Honda Civic is fitted with throttle position sensors. They’re integrated into the electronic throttle body as dual TP sensors (for redundancy) and work alongside dual accelerator pedal position (APP) sensors. On this model the TP sensors are not serviced separately—Honda supplies the throttle body as an assembly if a TP sensor fault is confirmed.

On a modern drive‑by‑wire Civic, the TPS tells the engine control module exactly where the throttle plate sits, so the car can match the driver’s request, manage idle, and keep emissions in check. Two TP sensors report plate angle, the ECU constantly cross‑checks them with the APP sensors at the pedal. If the numbers don’t line up, it’ll throw a code and may drop into limp mode to protect the engine and occupants.

There’s no scheduled replacement for TPS on the 2022 Civic. As part of routine servicing, a sensible plan is:

• Scan for fault codes and look at live data for TP1/TP2 and APP1/APP2 agreement. Common TP‑related codes include P0121–P0123 and P2135.
• Visually inspect the throttle body connector and loom for corrosion, moisture ingress, or chafing—common culprits before the sensor itself.
• If idle is rough or throttle response is sticky, clean the throttle body bore and blade with a suitable throttle‑body cleaner. Don’t force the blade by hand and don’t soak the electronics.
• If a TP sensor is out of range or correlation fails, replace the throttle body assembly with a quality unit and a new gasket. Torque fasteners to spec and use a scan tool to run the ETCS/idle learn procedure so it idles properly afterwards.

Owners may notice symptoms like an illuminated check engine light, uneven idle, poor fuel economy, lazy throttle response, or the CVT behaving oddly. A workshop with a capable scan tool (Honda HDS or equivalent) can confirm in minutes whether the TP sensors are behaving. When replacement is required, it’s typically a straightforward job under the bonnet, and a relearn procedure seals the deal. Sticking with genuine or OE‑quality parts, keeping connectors clean and dry, and giving the throttle body an occasional tidy‑up around the 60,000–100,000 km mark will keep the Civic happy for the long haul.

Popular questions

Does the 2022 Honda Civic have a throttle position sensor?
Yes. The 2022 Civic uses an electronic throttle body with dual built‑in throttle position sensors. They report the actual throttle plate angle to the ECU and are part of the throttle body assembly, not a separate bolt‑on sensor.

What are the signs a TPS is playing up on a 2022 Civic?
Common clues include a check engine light with codes like P0121–P0123 or P2135, rough or high idle, limp‑home behaviour, poor throttle response, and higher fuel use. A quick live‑data check for TP/APP agreement will usually pinpoint it.

Can the TPS be replaced on its own, or does the whole throttle body need changing?
On this model the TPS is integrated, so the fix is to replace the throttle body assembly. After fitting, a throttle/idle learn with a scan tool helps it settle into a smooth idle and proper response.
