Parts for your 2007 Honda Civic-Throttle position sensors

2007 Honda Civic throttle-position-sensors (TPS)

Based on the Honda Civic (2006–2011) Service Manual sections on the Electronic Throttle Control System, Honda’s parts catalogues listing dual “TP Sensor A/B” within the throttle body assembly, and common OBD-II diagnostics (DTCs P0121–P0123, P2135) used by Alldata/Mitchell, the 2007 Honda Civic is fitted with throttle-position-sensors. They’re integrated into the electronic (drive-by-wire) throttle body and are not a separate, adjustable unit.

On a 2007 Honda Civic, the throttle-position-sensors tell the engine computer exactly how far the throttle plate is open. This model runs a drive-by-wire setup, so there’s no cable under the bonnet, instead, the ECU uses the accelerator pedal position and the dual TPS signals to command the throttle motor. Two sensors (TP Sensor A and B) provide redundant, cross-checked signals for safety and smooth drivability. The ECU uses these readings to manage fuel delivery, ignition timing, idle stability, and even transmission behaviour on autos—so accurate TPS data makes the car feel crisp and consistent on the road.

There’s no scheduled replacement interval for throttle-position-sensors on this Civic. During regular servicing, it’s smart to:

• Inspect the throttle body for carbon build-up and clean it with throttle-body-safe cleaner (avoid flooding the sensor area).
• Check the TPS connector and loom for corrosion, damaged pins, or rubbed wiring.
• Verify battery health and grounds—low voltage can trigger TPS correlation faults.

Common clues that the throttle-position-sensors are playing up include a check engine light, poor throttle response, hunting idle, sudden limp mode, or uneven acceleration. Typical codes include P0121–P0123 (range/performance or circuit) and P2135 (TP Sensor A/B correlation).

If replacement is required, note that on most 2007 Civic variants the TPS is part of the throttle body assembly. That means swapping the complete unit, fitting a new gasket, reconnecting coolant hoses if fitted, and torquing fasteners correctly. After any throttle body work, perform an idle/throttle relearn—ideally with a scan tool, or by warming the engine to operating temperature and letting it idle with all loads off so the ECU can settle the new values. Clear fault codes and confirm the live data for both TP sensors tracks smoothly from closed to wide open with no drop-outs. With clean hardware, tight electrics, and a proper relearn, the Civic’s throttle response will be back to its best for thousands of kilometres.

Does the 2007 Honda Civic have a throttle-position-sensor?

Yes. It actually uses two throttle-position-sensors (TP Sensor A and B) built into the electronic throttle body. They work together to provide accurate, redundant feedback to the ECU.

Can the TPS be replaced separately on this model?

On most 2007 Civic trims, the TPS isn’t sold as a separate adjustable part. If the sensor fails, the usual fix is replacing the complete throttle body assembly, then carrying out a throttle/idle relearn.

What are the signs the TPS needs attention?

Drivers may notice a check engine light, sluggish or jumpy throttle response, unstable idle, or limp mode. Scanning may reveal codes like P0121–P0123 or P2135. Before replacement, always check for carbon build-up, wiring issues, and correct battery voltage.
