Parts for your 2002 Honda Stream-Camshaft sensor

2002 Honda Stream camshaft sensor — what it does and when to service it

Based on technical sources, the camshaft position (CMP) sensor is absolutely used on the 2002 Honda Stream. The Honda Stream 2001–2005 Service Manual (PGM-FI section) describes the CMP sensor as an input for fuel and ignition timing. Honda’s Electronic Parts Catalogue lists dedicated CMP sensors for both engines fitted to this model year: 37510‑PLC‑015 for the 1.7‑litre D17A and 37510‑PNB‑003 (intake/exhaust variants on some trims) for the 2.0‑litre K20A i‑VTEC. Common OBD‑II diagnostics for this vehicle include CMP-related DTCs (e.g., P0340/P0341) noted in Honda service literature and diagnostic databases. That confirms the camshaft sensor is relevant and fitted on the 2002 Stream.

The camshaft sensor on a 2002 Honda Stream feeds the ECU precise cam angle so it can sync fuel injection and ignition with the crank signal. On K‑series i‑VTEC engines, it also helps the ECU track variable cam timing events. The result is smooth starting, clean idle, decent fuel economy and proper power delivery across Aussie and Kiwi roads.

It’s not a scheduled replacement item, but it does deserve some love during servicing. A quick inspection of the plug and harness for oil wicking or brittle insulation goes a long way, especially on higher‑kilometre cars. If the check engine light pops with codes like P0340/P0341, or the Stream cranks longer than usual, misfires, surges, or drops into limp mode, the CMP sensor or its wiring is a prime suspect.

• D17A (1.7 SOHC, timing belt): one CMP sensor mounted at the cylinder head. Incorrect belt timing or a tired belt can trigger CMP correlation faults — rule that out before blaming the sensor.
• K20A (2.0 DOHC i‑VTEC, timing chain): typically an intake (and on some variants, exhaust) CMP sensor at the chain end. Chain wear or a sluggish VTC can mimic sensor issues.

When replacement is needed, choose an OE‑quality sensor with a fresh O‑ring. Disconnect the battery, unplug the connector, remove the hold‑down bolt, swap the sensor, lightly oil the new O‑ring, and refit. Tighten the retaining bolt to the service‑manual spec (about 12 N·m). Clear codes and verify with a warm idle and a short road test.

Good oil matters here. Regular changes with the correct viscosity help keep cam phasers (K20A) happy and reduce sludge that can contaminate sensor faces. If faults persist after replacing the sensor, check harness continuity, ECU grounds, and — for the K‑series — cam timing data to rule out mechanical correlation problems.

Popular questions

Does the 2002 Honda Stream definitely have a camshaft sensor?
Yes. Both factory engines use a camshaft position sensor. The D17A 1.7 has a single CMP at the head, while many K20A 2.0 i‑VTEC variants use an intake (and sometimes an exhaust) CMP sensor. It’s a core input for fuel, spark and cam timing control.

Where is the camshaft sensor located on a 2002 Stream?
On the D17A, it’s mounted on the cylinder head near the cam gear end. On K‑series engines, look at the timing chain end of the head — the intake CMP is near the top, some trims also have an exhaust CMP on the opposite cam.

Is it safe to drive with a faulty camshaft sensor?
It might still run, but expect hard starting, rough idle and poor economy. Extended driving can stress the catalyst and leave the car in limp mode. It’s best to diagnose and fix it promptly.
