Parts for your 2010 Honda Stream-Crank angle sensor

2010 Honda Stream crank angle sensor: purpose, care, and replacement

Technical sources confirm the 2010 Honda Stream is fitted with a crank angle sensor (Honda typically calls it a crankshaft position sensor, CKP). The Honda Stream RN6–RN9 service/workshop manuals for the R18A and R20A i‑VTEC engines describe the CKP sensor and related diagnostics (DTCs P0335–P0339), and Honda’s electronic parts catalog lists a dedicated crankshaft position sensor for 2010 models. So yes, the part is relevant and used on this vehicle.

On the 2010 Honda Stream, the crank angle sensor sits at the heart of how the engine runs. It monitors crankshaft speed and exact position, feeding that data to the ECU so it can fire the coils and injectors at the right moment. Without a clean, accurate signal, timing goes out the window—leading to hard starting, misfires, rough idle, stalling, or a complete no‑start. It also supports functions like variable valve timing control, so it’s essential for smooth power and decent fuel economy.

There’s no scheduled maintenance for the sensor itself—it’s a sealed, solid‑state unit—but a bit of care goes a long way. Keeping the connector dry and the wiring loom intact helps prevent intermittent faults. During routine servicing, it’s worth a quick look under the bonnet for oil or coolant leaks that could contaminate the sensor area. If the check engine light is on with codes like P0335 or P0336, proper diagnosis with a scan tool and a live‑data check should be done before replacing parts.

Replacement is straightforward for a competent tech. On the R18A/R20A engines, the sensor is typically mounted low on the front of the block near the crank pulley. Access is easiest from the right‑hand wheel arch with the splash guard loosened. The job involves disconnecting the battery, unplugging the connector, removing the retaining bolt, swapping the sensor and O‑ring, and refitting to the factory torque spec from the service manual. After installation, clear the codes, warm the engine fully, and perform an idle learn if needed. No coding is usually required on these Hondas.

• Common signs it’s on the way out: long cranking, sudden stalling, erratic tacho, poor idle, and DTCs P0335–P0339.
• Use quality OEM or reputable aftermarket parts to avoid signal issues.
• If the plug shows green corrosion, clean it and check the loom before condemning the sensor.

For owners in Australia and New Zealand, parts typically run in the ballpark of AUD/NZD $80–$250, with about 0.5–1.0 hour of labour depending on access and workshop rates.

Popular questions

Where is the crank angle sensor on a 2010 Honda Stream?
On R18A and R20A engines, it’s usually bolted low on the front of the engine block near the crank pulley, reading a toothed reluctor on the crank. Access is commonly via the right‑hand wheel arch after removing or loosening the splash guard.

What are the symptoms of a failing sensor, and can it just be cleaned?
Tell‑tales include long cranking or no‑start, sudden stalls, rough idle, the tacho dropping out, and fault codes P0335–P0339. If corrosion is only at the connector, cleaning the terminals can help. If the sensor itself has gone electrically open/short or has a weak signal, replacement is the fix.

Does it need regular replacement, and what does it cost?
There’s no scheduled change interval, many last the life of the vehicle. Expect roughly AUD/NZD $80–$250 for the part and about 0.5–1.0 hour of labour. No special programming is generally required—at most, an idle relearn after battery disconnection.
