Parts for your 2011 Honda Accord-Crank angle sensor

2011 Honda Accord crank angle sensor (CKP) — what it does and how to look after it

Technical sources confirm the 2011 Honda Accord does use a crank angle sensor, formally called the crankshaft position (CKP) sensor. The Honda Accord 2008–2012 Service Manual details CKP operation and testing, Honda’s electronic parts catalog lists “Sensor, Crankshaft Position” for both the 2.4‑litre K24Z engines (e.g., 37500‑R40‑A01) and the 3.5‑litre J35Z V6 (e.g., 37500‑R70‑A01), and Honda’s OBD‑II documentation references DTCs such as P0335/P0336 for CKP faults. So yes—on a 2011 Accord, a crank angle sensor is very much fitted and relevant.

On this Accord, the CKP is the ECU’s timekeeper. It reads the toothed wheel on the crank and tells the ECU exactly where the pistons sit, so fuel and spark land bang on. Without a clean CKP signal, the engine won’t start, may misfire, or can stall under load. The four‑cylinder’s sensor is usually mounted low at the front of the engine near the oil pump/timing cover, while the V6 locates it at the front timing area as well—easy enough to reach with the right access.

There’s no scheduled replacement interval, but the sensor and its connector appreciate a bit of preventative care during servicing. A tech will typically:

• Scan for pending codes and erratic CKP rpm signals.
• Inspect the connector and loom for heat-hardening, oil wicking, or green crust on terminals.
• Check for oil leaks around the front cover that can contaminate the sensor O‑ring.

Common clues it’s on the way out include extended crank or no‑start when hot, random stalling at idle, uneven idle, loss of power under acceleration, and the MIL with codes like P0335 or P0336. If replacement’s needed, go genuine or a top‑tier aftermarket unit—cheapies can cause phantom faults. Fit a fresh O‑ring, lightly lube it with clean engine oil, seat the sensor squarely, and tighten the retaining bolt to factory spec. Avoid yanking on the harness, route it exactly as Honda intended so it doesn’t rub through. After installation, clear codes and perform an idle learn if required for your engine: bring the engine to operating temp, ensure all loads off, and let it idle for several minutes. Most 2011 Accords don’t need a special CKP relearn procedure, but following the service manual process keeps the ECU happy.

For owners keen to keep their Accord chirpy, pairing regular scans with simple visual checks under the bonnet goes a long way. Stop oil leaks early, keep the connector dry, and the CKP will usually carry on for many kilometres without a fuss.

Where is the crank angle sensor on a 2011 Honda Accord?

On the 2.4‑litre K24Z, it’s mounted low on the front of the engine near the timing cover/oil pump area. On the 3.5‑litre J35 V6, it’s also at the front timing region. Access is from under the front of the car, removing splash shields makes life easier.

What are the usual symptoms and fault codes of a failing CKP on this model?

Expect long crank or hot no‑start, sudden stalling, rough idle, and poor acceleration. The check engine light may show P0335 (Crankshaft Position Sensor A Circuit) or P0336 (Range/Performance). Intermittent wiring faults can mimic a bad sensor, so test the harness and connector too.

Do they need to perform a relearn after replacing the sensor?

Generally, the 2011 Accord doesn’t require a dedicated CKP pattern relearn. Clear fault codes, ensure battery voltage is healthy, warm the engine fully, and complete an idle learn procedure per the service manual. A short road test with varied load helps the ECU stabilise fuelling and timing.
