Parts for your 2007 Honda Fit-Throttle position sensors

2007 Honda Fit throttle position sensors

Based on technical references, the 2007 Honda Fit (GD platform, L15A engine) does use throttle position sensors—two of them, in fact—but they’re built into the electronic throttle body as part of the drive‑by‑wire system. Honda’s 2007 Fit Service Manual (PGM‑FI, Electronic Throttle Control System) details “TP Sensor A/B” and corresponding DTCs (P0121–P0123, P0221–P0223). The Honda parts catalogue for the 2007 Fit/Jazz shows the sensors as non‑serviceable components of the throttle body assembly, and repair information services such as Mitchell1/ProDemand and ALLDATA describe the same integrated setup. That means there’s no separate, bolt‑on TPS to replace on its own.

• Technical sources: 2007 Honda Fit Service Manual (PGM‑FI ETCS: TP Sensor A/B, DTCs P0121–P0123, P0221–P0223)
• Honda EPC/parts catalogue for 2007 Fit/Jazz (GD): throttle body with integrated TP sensors
• Industry repair databases (Mitchell1/ProDemand, ALLDATA): drive‑by‑wire throttle body with dual TP sensors, not serviced separately

The throttle position sensors on a 2007 Honda Fit (Jazz) tell the ECU exactly how far the throttle plate is open. Because this model runs an electronic throttle (no cable), Honda uses dual, redundant TP sensors inside the throttle body to keep things accurate and safe. The ECU constantly compares Sensor A and Sensor B to manage airflow, fuel delivery, and ignition timing, which is why a dodgy reading can cause rough idle, hesitation, or limp‑home behaviour.

There’s no scheduled replacement for the TPS on this car. As part of regular servicing, it’s smart to keep the throttle body clean and the connector healthy. During a 20–30,000 km service, a technician will typically:

• Scan for fault codes (look for TP‑related DTCs like P0121–P0123, P0221–P0223)
• Inspect the throttle body connector and loom for corrosion, water ingress, or chafing
• Clean the throttle bore and plate with the correct cleaner (don’t flood the electronics, and don’t force the plate open)
• Check battery and charging voltage—low voltage can upset sensor readings

If the sensors fail, the fix is to replace the entire throttle body assembly, fit a new gasket, and then carry out an idle/throttle learn with a scan tool or Honda’s specified procedure. After any throttle body work or battery disconnect, an idle learn helps the ECU relearn target airflow. Many drivability complaints clear up once the body is clean, connectors are sorted, and the learn is done properly.

Typical signs it’s time to act include a surging or high idle, poor tip‑in response, sudden loss of power, or the MIL lighting up with the codes above. Because the sensors are integral, guessing and swapping single parts isn’t on, proper scan data, basic electrical checks, and methodical cleaning save time and money.

Does a 2007 Honda Fit actually have a TPS?

Yes. It has dual throttle position sensors built into the electronic throttle body. They aren’t serviced separately, if they fail, the throttle body assembly is replaced. This setup is documented in the Honda service manual and parts catalogue.

What symptoms point to a TPS/throttle body issue on a 2007 Fit?

Common clues are erratic or high idle, hesitation off the line, limp mode, and the check‑engine light with codes like P0121–P0123 or P0221–P0223. Before replacing anything, check the connector and wiring, clean the throttle body correctly, and perform an idle learn.

Can the TPS be calibrated after battery disconnection or cleaning?

The sensors themselves aren’t adjustable, but the ECU needs an idle/throttle learn. With a scan tool or by following Honda’s procedure (warm engine, all loads off, stable idle), the ECU relearns the correct airflow and throttle position values.
