2001 Honda Accord camshaft sensor — what it does and when to replace it

Based on technical references, the 2001 Honda Accord does use a camshaft position signal. The 1998–2002 Accord Factory Service Manual (Helm Inc.) identifies that the 4‑cylinder F23 engine’s cam timing signal comes from the TDC/CYP sensors integrated within the camshaft‑driven distributor, while the J30 V6 uses an external Camshaft Position (CMP) sensor on the cylinder head. Honda’s electronic parts catalogue lists the 4‑cyl “Sensor, Cylinder (CYP)” as part of the distributor assembly and a separate “Camshaft Position Sensor” for the V6. Common OBD‑II diagnostics in these manuals and service databases (e.g., P0341 for V6 CMP, P1381/P1382 for 4‑cyl CYP/TDC) further confirm the system’s presence and role.

For the 2001 Accord, the camshaft sensor helps the engine computer figure out which stroke each cylinder is on so it can time fuel injection and spark precisely. That means smoother starts, better fuel economy, lower emissions, and clean drivability around town and out on the open road. On the F23 four‑cylinder, that signal lives inside the distributor (it’s effectively the cam sensor, just packaged differently). On the J30 V6, it’s a stand‑alone sensor mounted on the head.

When these sensors age, owners may notice extended cranking, random misfires, a rough idle, sudden stalls at the lights, or limp‑home behaviour. The check‑engine light often chimes in with codes like P0341 on V6 cars, or P1381/P1382 on four‑cyl models.

As part of regular servicing, it’s smart to:

• Inspect the sensor connector and harness under the bonnet for oil contamination, brittle insulation, or loose terminals.
• For the four‑cyl, check the distributor shaft for play and oil leaks, internal sensors hate heat and oil mist.
• For the V6, look for oil seepage around the CMP sensor’s O‑ring and ensure the retaining bolt is snug to spec.
• Keep up with timing‑belt and rocker cover gasket intervals, tidy sealing keeps sensors clean and happy.

Replacement isn’t a routine interval item, but if faults persist after basic checks, swapping the sensor (or the distributor assembly on the 4‑cyl if the internal pickups are failing) is straightforward with hand tools. Use quality parts, fit a fresh O‑ring where applicable, clear codes, and verify with a short road test. A quick relearn via scan tool may help some ECUs stabilise idle sooner. Done right, the Accord is back to crisp starts and smooth kilometres without fuss.

Popular questions about the 2001 Honda Accord camshaft sensor

Where is the camshaft sensor on a 2001 Accord?
On the 4‑cylinder F23, it’s built into the cam‑driven distributor as the CYP/TDC pickup assembly. On the J30 V6, it’s a separate sensor mounted on the cylinder head (rear bank), accessible from the top under the bonnet.

What symptoms point to a bad camshaft sensor on this model?
Hard starting, intermittent stalling, uneven idle, flat spots on acceleration, and increased fuel use are typical. The dash may show a check‑engine light with codes like P0341 (V6) or P1381/P1382 (4‑cyl). Wiring or oil contamination at the connector can mimic sensor failure, so inspect that first.

Should it be replaced as preventative maintenance?
It’s not a scheduled replacement item. Instead, include the connector, wiring, and (for 4‑cyl) distributor health in regular inspections. Replace the sensor if faults are confirmed by diagnostics, or the distributor if internal pickups fail. Always refit seals and torque fasteners correctly to prevent future issues.
