Parts for your 2014 Honda Stream-Throttle position sensors

2014 Honda Stream throttle position sensors

Based on Honda factory service information for the second‑generation Stream (RN6–RN9, including the 2014 model year), the vehicle uses an electronic throttle control system with dual throttle position sensors (often called TP Sensor A and TP Sensor B) integrated into the throttle body assembly. This setup is documented in Honda technical literature covering the ETCS/DBW system and related DTCs (e.g., P0121–P0123, P0221–P0223, P2135). The accelerator pedal also carries an APP (accelerator pedal position) sensor. So yes—the 2014 Honda Stream is fitted with throttle position sensing, but it’s built into the electronic throttle body rather than being a stand‑alone, cable‑type sensor.

On a 2014 Honda Stream, the throttle position sensors tell the ECU exactly how far the throttle plate is open. Working alongside the accelerator pedal sensor and the throttle actuator motor, they help the ECU manage air intake, fuel delivery, ignition timing and idle control. The dual‑sensor design provides redundancy and cross‑checks, if their signals don’t agree, the ECU can drop the car into limp mode to protect the engine and maintain basic driveability.

When servicing, most owners won’t “maintain” the TPS individually because Honda supplies it as part of the electronic throttle body. Instead, good practice is to keep the throttle body clean, connectors sound, and wiring free of chafes. If idle is a bit rough, there’s a hesitation off the mark, the Check Engine lamp’s on, or fuel economy slides, it’s worth scanning live data for TP Sensor A/B agreement and checking for codes like P0121 or P2135. A dirty throttle bore can mimic sensor issues, so a careful clean can save unnecessary parts.

Replacement is typically the entire throttle body assembly rather than just the sensor. Genuine and quality aftermarket units come pre‑calibrated, once fitted, perform the Honda idle learn/throttle relearn so the ECU can adapt. Don’t force the throttle plate open by hand—use the pedal or a scan tool. Always disconnect the battery before unplugging the throttle body, and use a fresh gasket on refit to avoid air leaks.

Handy tips during service:

• Use a scan tool to compare TP Sensor A vs B, they should track smoothly with no dropouts.
• After cleaning or replacement, do an idle learn with all loads off and the engine at operating temp.
• If corrosion is found in the connector, fix that first—voltage reference and ground issues can trigger false TPS faults.

FAQs

Does the 2014 Honda Stream have a throttle position sensor?
Yes. It uses dual throttle position sensors integrated into the electronic throttle body. They work with the pedal sensor and throttle motor to control airflow and engine response.

Can the throttle position sensor be replaced on its own?
On this model it’s generally part of the throttle body assembly. In most cases, technicians replace the complete electronic throttle body rather than the sensor alone, then carry out an idle learn.

Do you need a relearn after cleaning or replacing the throttle body?
It’s recommended. An idle/throttle relearn helps the ECU recalibrate the throttle opening for stable idle and smooth take‑off. Many workshops use a scan tool, a basic manual procedure can also be followed if specified in the service info.
