Parts for your 2010 Honda Stream-Camshaft sensor

2010 Honda Stream camshaft-sensor — what it does and when to replace it

Based on technical references including the Honda Stream RN6–RN9 Service Manual (PGM-FI section: Camshaft Position [CMP] Sensor), Honda’s R18A/R20A i‑VTEC engine technical overview, and workshop data providers such as Autodata, the 2010 Honda Stream (1.8 R18A and 2.0 R20A) is fitted with a camshaft position sensor. It’s an essential input for the engine control unit.

The camshaft-sensor on a 2010 Honda Stream tells the ECU exactly where the camshaft is in relation to the crankshaft. That lets the car run true sequential fuel injection, time the spark properly, and command i‑VTEC/VTC cam phasing for smooth idle, decent grunt, and tidy fuel economy. When the sensor signal goes missing or messy, the ECU can’t trust cam timing, so it may revert to a safe map, stretch cranking times, and flip the check engine light on.

Typical hints the camshaft-sensor is on the way out include hard starting (especially warm), a lumpy idle, flat spots on acceleration, poor economy, and fault codes like P0340 or P0341. Sometimes it’ll feel like the top end has gone on holiday because VTC won’t advance as it should.

There’s no scheduled replacement for the camshaft-sensor on the Stream, it’s a fit-and-forget item until it fails. Preventative care is mostly about clean oil and tidy wiring. Fresh oil at the proper interval keeps the VTC system happy and reduces varnish that can creep into connectors. Under the bonnet, give the sensor plug and loom a quick visual during services — look for brittle conduit, oil wicking into the connector, or a loose retainer.

Replacement is straightforward for a competent DIYer or any workshop. Usual steps:

• Disconnect the battery negative.
• Locate the sensor at the timing-chain end of the cylinder head and unplug it.
• Remove the single retaining bolt, withdraw the sensor, and mind the O‑ring.
• Lightly oil the new O‑ring, install the new sensor, and tighten the bolt to workshop-spec (around 9–10 N·m is typical for small Honda sensor bolts).
• Reconnect, clear codes, and perform an idle relearn/short drive cycle.

Use an OE-quality part so the signal is clean and durable. If the light returns, check the crank sensor, timing-chain condition, and wiring before condemning anything else. For the 2010-honda-stream camshaft-sensor, a tidy install and clean oil usually sees it right for many more kilometres.

FAQs

Where is the camshaft-sensor on a 2010 Honda Stream?
It sits on the end of the cylinder head at the timing-chain side, under the bonnet near the upper engine mount area. You’ll spot a small sensor with a single bolt and a two- or three‑pin connector.

What fault codes point to a bad camshaft-sensor on the Stream?
Common codes include P0340 (Camshaft Position Sensor Circuit) and P0341 (Camshaft Position Sensor Range/Performance). Depending on symptoms, you might also see misfire codes. Always check wiring and oil contamination at the connector as part of diagnosis.

Does a new camshaft-sensor need programming?
No special programming is normally required. Clear the codes, then do a brief idle relearn and road test so the ECU can see stable signals again. If faults persist, check timing, the crank sensor, and the harness.
