Parts for your 2017 Honda Accord-Crank angle sensor

2017 Honda Accord crank angle sensor (crankshaft position sensor) — purpose, servicing and replacement

Yes, the 2017 Honda Accord is fitted with a crank angle sensor, commonly listed by Honda as the Crankshaft Position (CKP) Sensor. Honda’s factory workshop manual for the 2017 Accord PGM‑FI section details CKP operation and diagnostics, and the 2017 Accord DTC list includes CKP‑related fault codes P0335–P0339. Honda’s genuine parts catalogues for the 2.4L four‑cylinder, 3.5L V6, and Hybrid variants also enumerate a CKP sensor. So the part is relevant to every 2017 Accord powertrain.

On this Accord, the crank angle sensor keeps the engine management on song by telling the ECU exactly where the crankshaft is and how fast it’s spinning. Paired with the cam sensor, it lets the ECU time fuel injection and spark with pinpoint accuracy, manage variable valve timing, and stabilise idle. It reads a toothed wheel on the crank — when the pattern passes the sensor tip, the ECU counts teeth and gaps to calculate position and speed in real time. If it drops out, expect hard starts, intermittent stalling, a dead‑as‑a‑dodo no‑start, rough running at low revs, and the MIL lighting up with P0335–P0339.

The CKP isn’t a scheduled service item on a 2017 Accord, but it benefits from a quick look during routine servicing. Check the wiring for rub‑through, oil soaking, or brittle clips. Keep the area free of sludge and don’t blast the sensor with a pressure washer. If the engine has had metal debris from a past failure, the magnetic tip can pick up fines, a careful clean can help if readings are erratic, but if the sensor’s internal resistance or signal is out of spec, replacement is the go.

Location varies a touch by engine: on the 2.4L it’s mounted low near the crank pulley at the front of the block, on the 3.5L V6 it sits near the bellhousing, the Hybrid still uses a CKP on the engine block. Before swapping parts, a scan tool that shows live RPM while cranking will confirm the sensor’s alive. When replacing, disconnect the battery, use an OEM‑quality sensor with a new O‑ring, lightly oil the seal, and snug the retaining bolt to the workshop manual spec. Clear DTCs and perform an idle learn if the manual calls for it, a CKP “relearn” is typically not required on Hondas of this era. Most jobs run under an hour with basic hand tools under the bonnet. If faults persist, check the harness, connector pin fit, and the crank reluctor wheel for damage.

• Common signs: long crank/no‑start, stalling, misfires, erratic tacho, MIL with P0335–P0339
• Good practice: inspect wiring, avoid water ingress, verify with scan data before replacing
• Parts tip: stick with genuine or reputable aftermarket to avoid false triggers

Popular questions about the 2017 Honda Accord crank angle sensor

Where is the crank angle sensor on a 2017 Accord?

On the 2.4L four‑cylinder it’s mounted low on the front of the engine near the crank pulley and lower timing cover. On the 3.5L V6 it’s typically at the rear of the engine near the bellhousing. The Hybrid also has a CKP on the engine block. A quick peek from under the car with a torch usually spots it by the single retaining bolt and a two‑pin or three‑pin connector.

Do I need to program a new crank angle sensor?

Generally, no programming is needed on the 2017 Accord. Fit the new sensor, clear any fault codes, and perform an idle learn procedure if specified by the workshop manual. If codes return immediately, check wiring integrity and connector pin fit before assuming the new sensor is faulty.

What fault codes point to a bad CKP on this model?

The common ones are P0335 (Crankshaft Position Sensor A circuit) through to P0339 (intermittent). A no‑RPM reading while cranking on live data is another strong clue. Bear in mind wiring faults, a damaged reluctor wheel, or poor grounds can set the same codes, so testing beats guessing.
