Parts for your 2018 Honda Cr-v-Crank angle sensor

2018 Honda CR‑V crank angle sensor — what it does and how to look after it

Yes, the 2018 Honda CR‑V is fitted with a crank angle sensor (more commonly called the crankshaft position sensor, or CKP). Technical references back this up: Honda’s Service Information for the 2017–2019 CR‑V PGM‑FI section details the CKP sensor’s role and diagnostics (including DTCs P0335–P0339), and Honda’s electronic parts catalogue lists a crankshaft position sensor for both the L15B‑series 1.5‑litre turbo and the K24‑series 2.4‑litre engines used in this model year. OBD‑II standards also define P0335 as the CKP circuit fault, which appears in CR‑V diagnostic workflows.

On the 2018 CR‑V, the crank angle sensor tracks the exact position and speed of the crankshaft so the ECU knows when to fire the spark and inject fuel. It teams up with the camshaft sensor for precise timing, smooth starts, steady idle, solid acceleration, and accurate knock and misfire monitoring. Without a clean signal from this sensor, the engine can struggle to start, run roughly, or stall, and it’ll likely switch on the check engine light.

There’s no scheduled replacement interval for the CKP on this Honda, it’s a “fit and forget” item that’s replaced on condition. Good servicing practice is to keep an eye out for oil leaks around the front of the engine, ensure the sensor connector is clean and clipped firmly, and avoid letting metallic debris build up around the sensor tip. If faults crop up, scan for codes like P0335–P0339 and view live CKP RPM while cranking.

• Common symptoms: hard starting or no‑start when hot, intermittent stalling, rough idle, uneven power, poor fuel economy, and an engine light.
• Location: typically mounted near the crank pulley or transmission bellhousing on the engine block, depending on engine variant.
• Replacement tips: use an OEM‑quality sensor, replace the O‑ring if fitted, route the harness exactly as factory, torque the retaining bolt to spec, clear codes, and road‑test. Most jobs take about an hour.

Many ECUs will relearn the signal automatically, but using a scan tool to confirm stable RPM and no pending codes is smart. If faults persist, check for wiring damage, poor grounds, or reluctor wheel issues before blaming the new sensor. For owners clocking big kilometres or seeing coastal conditions, periodic connector inspection during routine servicing can save a stranded afternoon under the bonnet.

Popular questions

What are the signs a 2018 CR‑V crank angle sensor is failing?
Expect intermittent no‑start, random stalling at lights, rough idle, hesitant acceleration, and the check engine light. A scan tool often shows P0335–P0339 and an erratic or zero RPM reading during crank. Heat‑soak failures are common, where it restarts after cooling down.

Can it be driven with a bad crank angle sensor?
It’s risky. The engine may stall without warning, and fuel use can spike. Short trips to a workshop might be possible if it still starts, but towing is the safer bet if it’s cutting out or won’t restart hot.

Does a new sensor need calibration?
Usually no manual calibration is needed, the CR‑V’s ECU adapts automatically. After fitting, clear codes, verify clean RPM on live data, and complete a short drive cycle to confirm no returning faults.
