Parts for your 2015 Honda Civic-Crank angle sensor

2015 Honda Civic crank-angle sensor (crankshaft position sensor) — purpose, servicing and replacement

Yes — the 2015 Honda Civic is fitted with a crank-angle sensor, more commonly called the Crankshaft Position (CKP) sensor in Honda documentation. Technical references including Honda’s service information for the 2015 Civic engine controls, the OEM parts catalogue for both the 1.8L R-series and 2.4L K-series engines, and standard OBD-II diagnostics (DTCs P0335–P0339 for CKP circuit/performance) all confirm its presence and role.

This sensor keeps the engine management system in the loop on crank angle and speed, so it knows exactly when to fire the spark and inject fuel. It also helps the ECU coordinate with the cam sensors for proper variable valve timing and to detect misfires. Without a clean signal from the CKP, the engine can be hard to start, run rough, or not run at all.

Mounted near a toothed reluctor wheel on the crank, the sensor reads the passing teeth to generate a precise pulse train the ECU can interpret. Because timing is everything, even minor signal drop-outs can cause big drivability headaches.

• Common symptoms of a failing CKP: longer cranking or no-start, intermittent stalling when hot, sudden loss of power, erratic tachometer, and the check engine light with codes like P0335–P0339.

It’s not a scheduled replacement item, but it’s smart to inspect the connector and loom during routine servicing — especially if there are oil leaks at the front of the engine that could wick into the plug. Keep connectors clean and clipped in place, damaged wiring is a common culprit.

1. Disconnect the battery and let the car sit a few minutes under the bonnet.
2. Access the sensor (location varies: on the 1.8L it’s typically at the front of the block near the crank pulley, on the 2.4L it may be down by the oil pump/bellhousing area).
3. Unplug the connector, remove the retaining bolt, and withdraw the sensor. Expect an O-ring seal.
4. Lightly oil the new O-ring, seat the new sensor squarely, and tighten the bolt to the workshop spec.
5. Reconnect, clear any fault codes, and perform an idle learn or short drive cycle so the ECU settles in.

Use a quality OEM-equivalent sensor and don’t ignore accompanying issues like a damaged reluctor ring or oil contamination. The good news: on most Civics it’s a straightforward job and a reliable fix for start-and-stall gremlins. If fault codes persist, check harness integrity and engine grounds before chasing bigger problems.

FAQs — 2015 Honda Civic crank-angle sensor

Does the 2015 Civic actually have a crank-angle sensor?

It does. Honda labels it the Crankshaft Position (CKP) sensor, but it serves the same role as a crank-angle sensor. Location varies slightly between the 1.8L and 2.4L engines, yet both use a CKP to manage ignition timing, fuel delivery, and misfire detection.

What are the tell-tale signs mine is failing?

Hard starting, random stalling (often when hot), uneven idle, a dead tach needle during crank, and the check engine light with codes like P0335 are typical. If it won’t start at all but has spark and fuel pressure is OK, a CKP signal fault is a prime suspect.

Do I need to program anything after replacing it?

No coding is usually required. Clear any codes, then complete an idle learn or brief drive cycle so the ECU stabilises trims. Some scan tools offer an idle learn routine, otherwise a gentle 10–20 km mixed drive usually does the trick.
